Our focus is on adapting encryption technology to make it easy to use and widely available. Like free speech, the right to whisper is an necessary precondition for a free society. Without it, civil society and political freedom become impossible. As the importance of digital communication for civic participation increases, so does the importance of the ability to digitally whisper. LEAP is devoted to making the ability to whisper available to all internet users. + +LEAP is a non-profit organization registered in the state of Washington, USA. THe people who create LEAP live around the world, including: Bahía Blanca (Argentina), Berlin (Germany), Hamburg (Germany), La Paz (Bolivia), London (UK), Madrid (Spain), Montreal (Quebec, Canada), New York City (NY, USA), Paris (France), Seattle (WA, USA), São Paulo (Brazil), Santiago (Chile). + +# About LEAP technology + +LEAP's approach is unique: we are making it possible for any service provider to easily deploy secure services and for people to use these services without needing to learn new software or change their behavior. These services are based on open, federated standards, but done right: the provider does not have access to the user's data, and we use open protocols in the most secure way possible. + +On the server side we have created the LEAP Platform, a "provider in a box" set of complementary packages and server recipes automated to lower the barriers of entry for aspiring secure service providers. On the client side, we have created a cross-platform application called Bitmask that automatically configures itself once a user has selected a provider and which services to enable. Bitmask provides a local proxy that a standard email client can connect to, and allows for easy one-click Virtual Private Network (VPN) service. + +Email continues to be a vital communication tool, but is difficult to use securely. Unfortunately, when people to use secure email they often use it in ways that compromise their confidentiality and the confidentiality of the people they communicate with. Even worse, current technology for secure email is vulnerable to numerous methods of association-mapping--information that can be highly sensitive in its own right. + +The LEAP email system has several security advantages over typical encryption applications: if not already encrypted, incoming email is encrypted so that only the recipient can read it; email is always stored client-encrypted, both locally and when synchronized with the server; all message relay among service providers is required to be encrypted when possible; and public keys are automatically discovered and validated. In short, the Bitmask app offers full end-to-end encryption, quietly handling the complexities of public key encryption and allowing for backward compatibility with legacy email when necessary. Because the LEAP system is based on open, federated protocols, the user is able to change providers at will, preventing provider dependency and lock-in. + +In addition to encrypted email, Bitmask offers automatically self-configuring encrypted internet proxy (aka VPN). Most VPN technology can be a pain to configure correctly without introducing vulnerabilities of DNS leakage, IPv6 leakage, and failing into an open, unencrypted state. The goals for LEAP’s VPN service are to make it so easy to use that people will want to keep it on all the time, and to make it more secure than most other VPN services. + +For more information, see our [[documentation => docs]], [[talk slides => https://leap.se/slides/]], or [[email overview => email]]. diff --git a/pages/about-us/grantwriter.md b/pages/about-us/grantwriter.md new file mode 100644 index 0000000..394a1b4 --- /dev/null +++ b/pages/about-us/grantwriter.md @@ -0,0 +1,65 @@ +@title = "Job posting for grant writer" + +Overview +======================== + +LEAP Encryption Access Project (https://leap.se) is looking for a grant writer with a high-level understanding of the grant writing process, extensive experience writing successful proposals for highly competitive grants, excellent time management, and project management skills along with excellent communication skills.

We released 0.5.1 three weeks ago and have made public our 0.5.2 release candidate. 0.5.1 and 0.5.2rc improvements include: + +1. Autostart - If you have EIP on and shutdown your phone, Bitmask will autostart EIP once the phone is running again. +2. Gradle support - This only matters to developers, and they'll know what this means, so no more words +3. Signup support - You can register a new account with a LEAP provider from the android client. + +Autostart still has some glitches due to some problems with ics-openvpn. Next weeks we'll address these issues by cleaning and updating our ics-openvpn codebase. So hold your breath for the next 3 weeks, you'll hopefully see a very good 0.5.2 (or even 0.6!) release. + +Download: + +* https://play.google.com/store/apps/details?id=se.leap.bitmaskclient +* https://downloads.leap.se/client/android/Bitmask-Android-0.5.2-RC1.apk + +Changelog: + +* https://raw.githubusercontent.com/leapcode/bitmask_android/master/CHANGELOG + +Client +================== + +The client focus was towards fixing a security problem that exists in every VPN client to this date, which is: if VPN fails in any way, your traffic gets leaked out of the secure network. + +We leverage the Linux firewall to block all traffic outside of the computer except for the VPN gateways.

It contains a couple of security improvements that inaugurate a series of small but important features that will try to satisfy security minded people. + +The most important security feature added in this release is the openvpn persistent tun integration with our client. Once your device establishes a vpn tunnel, and as long as you keep EIP switch ON, you'll not route any traffic outside the vpn tunnel while the vpn is being established. Other features include earlier autostart launch, prompt to log in if necessary, and man in the middle prevention. + +Regarding bug fixes, we've finally removed the second notification that was annoying some users. The reason of its removal will be soon documented.

This separation paves the way for starting Bitmask during the boot process, and attach the current graphical client afterwards. And maybe even having cli or html5 clients in the near future, the possibilities that it opens are many! + +It also allows us to finally close an annoying bug that was causing high CPU usage when using the client. + +While we were at it, we gave a little face lift to the UI: the provider selection is in a more prominent place now, and some other little interface tweaks made their way into this last release.

If you install everything into +`/usr/lib/python2.7/site-packages` (or whatever your platform's standard +location is), it's easy to end up in a situation where you +unintentionally upgrade an application that shouldn't be upgraded. + +Read more about it in the [project documentation +page](http://www.virtualenv.org/en/latest/virtualenv.html). + +### Create and activate your dev environment + +You first create a virtualenv in any directory that you like: + + $ mkdir ~/Virtualenvs + $ virtualenv ~/Virtualenvs/bitmask + $ source ~/Virtualenvs/bitmask/bin/activate + (bitmask)$ + +Note the change in the prompt. + +### Avoid compiling PySide inside a virtualenv + +If you attempt to install PySide inside a virtualenv as part of the rest +of the dependencies using pip, basically it will take ages to compile. + +As a workaround, you can run the following script after creating your +virtualenv. It will symlink to your global PySide installation (*this is +the recommended way if you are running a debian-based system*): + + $ pkg/postmkvenv.sh + +A second option if that does not work for you would be to install PySide +globally and pass the `--system-site-packages` option when you are creating +your virtualenv: + + $ apt-get install python-pyside + $ virtualenv --system-site-packages . + +After that, you must export `LEAP_VENV_SKIP_PYSIDE` to skip the +installation: + + $ export LEAP_VENV_SKIP_PYSIDE=1 + +And now you are ready to proceed with the next section. + +### Install python dependencies + +You can install python dependencies with `pip`. If you do it inside your +working environment, they will be installed avoiding the need for +administrative permissions: + + $ pip install -r pkg/requirements.pip + +This step is not strictly needed, since the `setup.py develop` in the next +paragraph with also fetch the needed dependencies. But you need to know abou it: +when you or any person in the development team will be adding a new dependency, +you will have to repeat this command so that the new dependencies are installed +inside your virtualenv. + +Install Bitmask +--------------- + +Normally we would install the `leap.bitmask` package as any other package +inside the virtualenv. +But, instead, we will be using setuptools **development mode**. The difference +is that, instead of installing the package in a permanent location in your +regular installed packages path, it will create a link from the local +site-packages to your working directory. In this way, your changes will always +be in the installation path without need to install the package you are working +on.:: + + (bitmask)$ python2 setup.py develop --always-unzip + +After this step, your Bitmask launcher will be located at +`~/Virtualenvs/bitmask/bin/bitmask`, and it will be in the path as long as you +have sourced your virtualenv. + +Note: the `--always-unzip` option prevents some dependencies to be installed in +a zip/egg, which causes some issues with libraries like 'scrypt' that needs to +access to the files directly from the filesystem. + +Compile Qt resources +-------------------- + +We also need to compile the resource files: + + (bitmask)$ make + +Note: you need to repeat this step each time you change a `.ui` file. + +Running openvpn without root privileges +--------------------------------------- + +In linux, we are using `policykit` to be able to run openvpn without root +privileges, and a policy file is needed to be installed for that to be +possible. +The setup script tries to install the policy file when installing bitmask +system-wide, so if you have installed bitmask in your global site-packages at +least once it should have copied this file for you. + +If you *only* are running bitmask from inside a virtualenv, you will need to +copy this file by hand: + + $ sudo cp pkg/linux/polkit/se.leap.bitmask.policy /usr/share/polkit-1/actions/ + +Installing the bitmask EIP helper +--------------------------------- + +In linux, we have a `openvpn` and `firewall` helper that is needed to run EIP. +You need to manually copy it from `bitmask_client/pkg/linux/bitmask-root`. +Use the following command to do so: + + $ sudo cp bitmask_client/pkg/linux/bitmask-root /usr/sbin/ + + +Running! +-------- + +If everything went well, you should be able to run your client by invoking +`bitmask`.

We are engaged in a three-week release cycle with minor +releases that are as stable as possible. + +However, if you want to test that some issue has *really* been fixed +before the next release is out (if you are testing a new provider, for +instance), you are encouraged to try out the latest in the development +branch. If you do not know how to do that, or you prefer an automated +script, keep reading for a way to painlessly fetch the latest +development code. + +We have put together a script to allow rapid testing in different +platforms for the brave souls like you. Check it out in the +*Using automagic helper script* section of the +[Hacking](client/dev-environment) page only that in a more compact +way suitable (ahem) also for non developers. + +> **note** +> +> At some point in the near future, we will be using standalone bundles +> \<standalone-bundle\> with the ability to self-update. + +### Local config files + +If you want to start fresh without config files, just move them. In +linux: + + mv ~/.config/leap ~/.config/leap.old + +### Testing the packages + +When we have a release candidate for the supported platforms, we will +announce also the URI where you can download the rc for testing in your +system.

With Nicknym, the user is able to think solely in terms of nickname, while still being able to communicate with a high degree of security (confidentiality, integrity, and authenticity). Essentially, Nicknym is a system for binding human-memorable nicknames to a cryptographic key via automatic discovery and automatic validation. + +Nicknym is a federated protocol: a Nicknym address is in the form `username@domain` just alike an email address and Nicknym includes both a client and a server component. Although the client can fall back to legacy methods of key discovery when needed, domains that run the Nicknym server component enjoy much stronger identity guarentees. + +Nicknym is key agnostic, and supports whatever public key information is available for an address (OpenPGP, OTR, X.509, RSA, etc). + +**Why is Nicknym needed?** + +Existing forms of secure identity are deeply flawed. These systems rely on either a single trusted entity (e.g. Skype), a vulnerable Certificate Authority system (e.g. S/MIME), or key identifiers that are not human memorable (e.g. fingerprints used in OpenPGP, OTR, etc). When an identity system is hard to use, it is effectively compromised because too few people take the time to use it properly. + +The broken nature of existing identities systems (either in security or in usability) is especially troubling because identity remains a bedrock precondition for any message security: you cannot ensure confidentiality or integrity without confirming the authenticity of the other party. Nicknym is a protocol to solve this problem in a way that is backward compatible, easy for the user, and includes very strong authenticity. + +Goals +========================================== + +**High level goals** + +* Pseudo-anonymous and human friendly addresses in the form `username@domain`. +* Automatic discovery and validation of public keys associated with an address. +* The user should be able to use Nicknym without understanding anything about public/private keys or signatures. + +**Technical goals** + +* Wide utility: nicknym should be a general purpose protocol that can be used in wide variety of contexts. +* Prevent dangerous actions: Nicknym should fail hard when there is a possibility of an attack. +* Minimize false positives: because Nicknym fails hard, we should minimize false positives where it fails incorrectly. +* Resistant to malicious actors: Nicknym should be externally auditable in order to assure service providers are not compromised or advertising bogus keys. +* Resistant to association analysis: Nicknym should not reveal to any actor or network observer a map of a user's associations. + +**Non-goals** + +* Nicknym does not try to create a decentralized peer-to-peer identity system.

Nicknym Key Auditing Protocol () + + +Nicknym attempts to solve the binding problem using several strategies: + +1. **TOFU**: +1. **Provider Endorsement**: +1. **Network Perspective**: + +Related work +=================================== + +**The Binding Problem** + +Nicknym attempts to solve the problem of binding a human memorable identifier to a cryptographic key. If you have the identifier, you should be able to get the key with a high level of confidence, and vice versa. The goal is to have federated, human memorable, globally unique public keys. + +There are a number of established methods for binding identifier to key: + +* [X.509 Certificate Authority System](https://en.wikipedia.org/wiki/X.509) +* Trust on First Use (TOFU) +* Mail-back Verification +* [Web of Trust (WOT)](http://en.wikipedia.org/wiki/Web_of_trust) +* [DNSSEC](https://en.wikipedia.org/wiki/Dnssec) +* [Shared Secret](https://en.wikipedia.org/wiki/Socialist_millionaire) +* [Network Perspective](http://convergence.io/) +* Nonverbal Feedback (a la ZRTP) +* Global Append-only Log +* Key fingerprint as unique identifiers + +The methods differ widely, but they all try to solve the same general problem of proving that a person or organization is in control of a particular key. + +**Nyms** + +http://nyms.io + +**DANE** + +[DANE](https://datatracker.ietf.org/wg/dane/), and the specific proposal for [OpenPGP user keys using DANE](https://datatracker.ietf.org/doc/draft-wouters-dane-openpgp/), offer a standardized method for securely publishing and locating OpenPGP public keys in DNS. + +As noted above, DANE will be very cool if ever adopted widely, but user keys are probably not a good fit for DNSSEC, because of issues of observability of DNS queries and complexity on the server and client end. + +By relying on the central authority of the root DNS zone, and the authority of TLDs (many of which are of doubtful trustworthiness), DANE potentially suffers from problems of compromised or nefarious authorities. Because DNS queries are not secure, a single user is particularly vulnerable to MiTM attacks that rewrite all their DNS queries. Adopting an alternate DNS query system, like [DNSCurve](http://dnscurve.org/), [DNSCrypt](https://www.opendns.com/technology/dnscrypt/), an alternate HTTPS based API, or restricting DNS queries to a VPN, would go a long way to fix this problem, and would effectively turn any supporting DNS server into a network perspectives notary. Regardless, the other problems with using DANE for user keys remain. + +**DIME** + +DIME, formerly DarkMail, uses DNSSEC for provider endorsement, in a manner similar to DANE. Each key endorsement includes the fingerprint of the previously endorsed key, allowing for some limited form of eventual consistency auditing. + +**End-To-End** + +https://code.google.com/p/end-to-end/wiki/KeyDistribution + +Certificate Transparency, but applied to email addresses. + +**Prism Proof Email** + +http://prismproof.org/ + +* S/MIME +* TOFU for legacy clients. Most mail user agents already support S/MIME, and will TOFU the key when they get a new message. + +**STEED** + +[STEED](http://g10code.com/steed.html) is a proposal with very similar goals to Nicknym. In a nutshell, Nicknym basically looks very similar to STEED when the domain owner does not support Nicknym. STEED includes four main ideas: + +* trust upon first contact: Nicknym uses this as well, although this is the fallback mechanism when others fail. +* automatic key distribution and retrieval: Nicknym uses this as well, although we used HTTP for this instead of DNS. +* automatic key generation: Nicknym is designed specifically to support automatic key generation, but this is outside the scope of the Nicknym protocol and it is not required. +* opportunistic encryption: Again, Nicknym is designed to support opportunistic encryption, but does not require it. + +Additional differences include: + +* Nicknym is key agnostic: Nicknym does not make an assumption about what types of public keys a user wants to associate with their address. +* Nicknym is protocol agnostic: Nicknym can be used with SMTP, XMPP, SIP, etc. +* Nicknym relies on service provider adoption: With Nicknym, the strength of verification of public keys rests the degree to which a service provider adopts Nicknym. If a service provider does not support Nicknym, then effectively Nicknym opperates like STEED for that domain. + +**The Simple Thing** + +"The Simple Thing" (TST) is not really a protocol, but it could be. The idea is to just do the simple thing, which is to ignored any type of key endorsement and just TOFU all keys and allow people who care to manually verify fingerprints of the keys they hold. + +In all the other proposals, the burden of key validation is on the person who owns the key. TST works in the opposite way: all the burden for key validation is placed on the person using the public key, not on the key's owner. + +If written as a rule, TST might look like this: + +1. The client should use whatever latest key is advertised inline via headers in email it receives. Ideally, this would be validated by the +provider via a very simple mechanism (such as grab user Bob's key from this well-known https URL or DNSSEC/DANE). +2. To cold start, sender can grab recipient's key via this well-known method. +3. Sender should confirm before sending a message that they have the most up to date key. Messages received that are encrypted to unsupported keys should be bounced. + +For a long discussion of the simple thing, see [messaging list](https://moderncrypto.org/mail-archive/messaging/2014/000855.html) + +**WebID and Mozilla Persona** + +What about [WebID](http://www.w3.org/wiki/WebID) or [Mozilla Persona](https://www.mozilla.org/en-US/persona/)? These are both interesting standards for cryptographically proving identify, so why do we need something new? + +These protocols, and the poorly conceived OpenID Connect, are designed to address a fundamentally different problem: authenticating a user to a website. The problem of authenticating users to one another requires a different architecture entirely. There are some similarities, however, and in the long run a Nicknym provider could also be a WebID and Mozilla Persona provider. + + +Nicknym protocol +============================== + +Definitions +------------------------- + +General terms: + +* **address**: A globally unique handle in the form username@domain (i.e. an email, SIP, or XMPP address) that we attempt to bind to a particular key. + +Actors: + +* **user**: the person with an email account through a service provider. +* **provider**: A service provider that offers end-user services on a particular domain. +* **key manager**: The key manager is a trusted user agent that is responsible for storing a database of all the keys for the user, updating these keys, and auditing the endorsements of the user's own keys. Typically, the key manager will run on the user's device, but might be running on any device the user chooses to trust. +* **key directory**: An online service that stores public keys and allows clients to search for keys by address or fingerprint. A key directory does not make any assertions regarding the validity of an address + key binding. Existing OpenPGP keyservers are a type of key directory in this context, but several of the key validation proposals include new protocols for key directories. +* **key endorser**: A key endorser is an organization that makes assertions regarding the binding of username@domain address to public key, typically by signing public keys. When supported, all such endorsement signatures must apply only to the uid corresponding to the address being endorsed. +* **nickagent**: A key manager that supports nicknym. +* **nickserver**: A daemon that acts as a key directory and key endorser for nicknym. + +Keys: + +* **user key**: A public/private key pair associated with a user address. If not specified, "user key" refers to the public key. +* **endorsement key**: The public/private key pair that a service provider or third party endorser uses to sign user keys. +* **provider key**: A public/private key pair owned by the provider used as an endorsement key. +* **validated key**: A key is "validated" if the nickagent has bound the user address to a public key. + +Key actions: + +* **key discovery**: The act of encountering a new key, either inline the message, via URL, or via a key directory. +* **verified key transition**: A process where a key owner generates a new public/private key pair and signs the new key with a prior key. Someone verifying this new key then must check to see if there is a signature on the new key from a key previously validated for that particular email address. In effect, "verified key transition" is a process where verifiers treat all keys as name-constrained signing authorities, with the ability to sign any new key matching the same email address. In the case of a system that supports signing particular uids, like OpenPGP, the signatures for key transition must apply only to the relevant uid. +* **key registration**: the key has been stored by the key manager, and assigned a validation level. The user agent always uses registered keys. This is analogous to adding a key to a user's keyring, although implementations may differ. + +Key information: + +* **binding information**: evidence that the key manager uses to make an educated guess regarding what key to associate with what email address. This information could come from the headers in an email, a DNS lookup, a key endorser, etc. +* **key validation level**: the level of confidence the key manager has that we have the right key for a particular address. For automatic key management, we don't say that a key is ever "trusted" unless the user has manually verified the fingerprint. + + +Nickserver requests +----------------------- + +A nickagent will attempt to discover the public key for a particular user address by contacting a nickserver. The nickserver returns JSON encoded key information in response to a simple HTTP request with a user's address. For example: + + curl -X POST -d address=alice@domain.org https://nicknym.domain.org:6425 + +* The port is always 6425. +* The HTTP verb may be POST or GET. +* The request must use TLS (see [Query security](#Query.security)). +* The query data should have a single field 'address'. +* For POST requests to nicknym.domain.org, the query data may be encrypted to the the public OpenPGP key nicknym@domain.org (see [Query security](#Query.security)). +* The request may include an "If-Modified-Since" header. In this case, the response might be "304 Not Modified". + +Requests may be local or foreign, and for user keys or for provider keys. + +* **local** requests are for information that the nickserver is authoritative. In other words, when the requested address is for the same domain that the nickserver is running on. +* **foreign** request are for information about other domains. +* **user key** requests are for addresses in the form "username@domain". +* **provider key** requests are for addresses in the form "domain". + +**Local, Provider Key request** + +For example: + + https://nicknym.domain.org:6425/?address=domain.org + +The response is the authoritative provider key for that domain. + +**Local, User Key request** + +For example: + + https://nicknym.domain.org:6425/?address=alice@domain.org + +The nickserver returns authoritative key information from the provider's own user database. Every public key returned for local requests must be signed by the provider's key. + +**Foreign, Provider Key request** + +For example: + + https://nicknym.domain.org:6425/?address=otherdomain.org + +1. First, check the nickserver's cache database of discovered keys. If the cache is not old, return this key. This step is skipped if the request is encrypted to the foreign provider's key. +2. Otherwise, fetch provider key from the provider's nickserver, cache the result, and return it. + +**Foreign, User Key request** + +For example: + + https://nicknym.domain.org:6425/?address=bob@otherdomain.org + +* First, check the nickserver's database cache of nicknyms. If the cache is not old, return the key information found in the cache. This step is skipped if the request is encrypted to a foreign provider key. +* Otherwise, attempt to contact a nickserver run by the provider of the requested address. If the nickserver exists, query that nickserver, cache the result, and return it in the response. +* Otherwise, fall back to querying existing SKS keyservers, cache the result and return it. +* Otherwise, return a 404 error. + +If the key returned for a foreign request contains multiple user addresses, they are all ignored by nicknym except for the user address specified in the request. + +Nickserver response +--------------------------------- + +The nickserver will respond with one of the following status codes: + +* "200 Success": found keys for this address, and the result is in the body of the response encoded as JSON. +* "304 Not Modified": if the request included an "If-Modified-Since" header and the keys in question have not been modified, the response will have status code 304. +* "404 Not Found": no keys were found for this address. +* "500 Error": An unknown error occurred. Details may be included in the body. + +Responses with status code 200 include a body text that is a JSON encoded map with a field "address" plus one or more of the following fields: "openpgp", "otr", "rsa", "ecc", "x509-client", "x509-server", "x509-ca". For example: + + { + "address": "alice@example.org", + "openpgp": "6VtcDgEKaHF64uk1c/crFhRHuFW9kTvgxAWAK01rXXjrxEa/aMOyXnVQuQINBEof...." + } + +Responses with status codes other than 200 include a body text that is a JSON encoded map with the following fields: "address", "status", and "message". For example: + + { + "address": "bob@otherdomain.org", + "status": 404, + "message": "Not Found" + } + +A nickserver response is always signed with a OpenPGP public signing key associated with the provider. Both successful AND unsuccessful responses are signed. Responses to successful local requests must be signed by the key associated with the address "nicknym@domain.org".

Using a commercial CA certificate distributed with the host operating system. +2. Using DANE TLSA record to discover and validate the server certificate. +3. Using a seeded CA certificate (see [Discovering nickservers](#Discovering.nickservers)). +4. Using a custom self-signed CA certificate discovered for the domain, so long as the CA certificate was discovered via #1 or #2 or #3. Custom CA certificates may be discovered for a domain by making a provider key request of a nickserver (e.g. https://nicknym.known-domain.org/?address=new-domain.org). + +Optionally, a nickagent may make an encrypted query like so: + +0. Suppose the nickagent wants to make an encrypted query regarding the address alice@domain-x.org. +1. Nickagent discovers the public key for nicknym@domain-y.org. +2. The nickagent makes a POST request to a nickserver with two fields: address and ciphertext. +3. The address only contains the domain part of the address (unlike an unencrypted request). +4. The ciphertext field is encrypted to the public key for nicknym@domain-y.org. The corresponding cleartext contains the full address on the first line followed by randomly generated symmetric key on the second line. +5. If the request was local, the nickserver handles the request. If the request for foreign, the nickserver proxies the request to the domain specified in the address field. +6. When the request gets to the right nickserver, the body of the nickserver response is encrypted using using the symmetric key. The first line of the response specifies the cipher and mode used (allowed ciphers TBD). + +Comment: although it may seem excessive to encrypt both the request via TLS and the request body via OpenPGP, the reason for this is that many requests will not use OpenPGP. + +Automatic key validation +---------------------------------- + +A key is "validated" if the nickagent has bound the user address to a public key. + +Nicknym supports three different levels of key validation: + +* Level 3 - **path trusted**: A path of cryptographic signatures can be traced from a trusted key to the key under evaluation. By default, only the provider key from the user's provider is a "trusted key". +* Level 2 - **provider signed**: The key has been signed by a provider key for the same domain, but the provider key is not validated using a trust path (i.e. it is only registered) +* Level 1 - **registered**: The key has been encountered and saved, it has no signatures (that are meaningful to the nickagent). + +A nickagent will try to validate using the highest level possible. + +Automatic renewal +----------------------------- + +A validated public key is replaced with a new key when: + +* The new key is **path trusted** +* The new key is **provider signed**, but the old key is only **registered**. +* The new key has a later expiration, and the old key is only **registered** and will expire "soon" (exact time TBD). +* The agent discovers a new subkey, but the master signing key is unchanged. + +In all other cases, the new key is rejected. + +The nickagent will attempt to refresh a key by making request to a nickserver of its choice when a key is past 3/4 of its lifespan and again when it is about to expire. + +Nicknym encourages, but does not require, the use of short lived public keys, in the range of X to Y days. It is recommended that short lived keys are not uploaded to OpenPGP keyservers. + +Automatic invalidation +---------------------------- + +A key is invalidated if: + +* The old key has expired, and no new key can be discovered with equal or greater validation level. + +This means validation is a one way street: once a certain level of validation is established for a user address, no client should accept any future keys for that address with a lower level of validation. + +Discovering nickservers +-------------------------------- + +It is entirely up to the nickagent to decide what nickservers to query. If it wanted to, a nickagent could send all its requests to a single nickserver. + +However, nickagents should discover new nickservers and balance their queries to these nickservers for the purposes of availability, load balancing, network perspective, and hiding the user's association map. + +Whenever the nickagent is asked by a locally running application for a public key corresponding to an address on the domain `domain.org`, it may check to see if the host `nicknym.domain.org` exists. If the domain resolves, then the nickagent may add it to the pool of known nickservers. A nickagent should only perform this DNS check if it is able to do so over an encrypted tunnel. + +Additionally, a nickagent may be distributed with an initial list of "seed" nickservers. In this case, the nickagent is distributed with a copy of the CA certificate used to validate the TLS connection with each respective seed nickserver. + +Cross-provider signatures +---------------------------------- + +Nicknym does not support user signatures on user keys. There is no trust path from user to user. However, a service provider may sign the provider key of another provider. + +To be written. + +Auditing +---------------------------- + +In order to keep the user's provider from handing out bogus public keys, a nickagent should occasionally make foreign queries of the user's own address against nickservers run by third parties. The recommended frequency of these queries is once per day, at a random time during local waking hours. + +In order to prevent a nickserver from handing out bogus provider keys, a nickagent should query multiple nickservers before a provider key is registered or path trusted. + +Possible attacks: + +**Attack 1 - Intercept Outgoing:** + +* Attack: provider `A` signs an impostor key for provider `B` and distributes it to users of `A` (in order to intercept outgoing messages sent to `B`). +* Countermeasure: By querying multiple nickservers for the provider key of `B`, the nickagent can detect if provider `A` is attempting to distribute impostor keys. + +**Attack 2 - Intercept Incoming:** + +* Attack: provider `A` signs an impostor key for one of its own users, and distributes to users of provider `B` (in order to intercept incoming messages). +* Countermeasure: By querying for its own keys, a nickagent can detect if a provider is given out bogus keys for their addresses. + +**Attack 3 - Association Mapping:** + +* Attack: A provider tracks all the requests for key discovery in order to build a map of association. +* Countermeasure: By performing foreign key queries via third party nickservers, an agent can prevent any particular entity from tracking their queries. + +Known vulnerabilities +------------------------------------------ + +The nicknym protocol does not yet have a good solution for dealing with the following problems: + +* Enumeration attack: an attacker can enumerate the list of all users for a provider by simply querying every possible username combination. We have no defense against this, although it would surely take a while. +* DDoS attack: by their very nature, nickservers perform a bit of work for every request. Because of this, they are vulnerable to be overloaded by a a flood of bogus requests. +* Besmirch attack: a MitM attacker can sully the reputation of a provider by generating many bad responses (responses signed with the wrong key), thus leading other nickservers and nicknym agents to consider the provider compromised. + +Future enhancements +--------------------- + +**Additional discovery mechanisms** + +In addition to nickservers and SKS keyservers, there are two other potential methods for discovering public keys: + +* **Webfinger** includes a standard mechanism for distributing a user's public key via a simple HTTP request. This is very easy to implement on the server, and very easy to consume on the client side, but there are not many webfinger servers with public keys in the wild. +* **DNS** is used by multiple competing standards for key discovery. When and if one of these emerges predominate, Nicknym should attempt to use this method when available. + +Discussion +---------------------- + +*Why not use WoT?* Most users are empirically unable to properly maintain a web of trust. The concepts are hard, it is easy to mess up the signing practice, most people default to TOFU anyway, and very few users use revocation properly. Most importantly, the WOT exposes a user's social network, potentially highly sensitive information in its own right. When first proposed, WOT was a clever innovation, but contemporary threats have greatly reduced its usefulness. + +*Why not use DANE/DNSSEC?* DANE is great for discovery and validation of server keys, but there are many reasons why it is not so good for user keys: DNS records are slow to update; DNS queries are observable, unlike HTTP over TLS; it is difficult for a provider to publish thousands of keys in DNS; it is much easier for a client to do a simple HTTP fetch (and more possible for HTML5 clients). Also, RSA Public keys will soon be too big for UDP packets (though this is not true of ECC), so putting keys in DNS will mean putting a URL to a key in DNS, so you might as well just use HTTP anyway. + +*Why not use Shared Secret?* Shared secrets, like with the Socialist Millionaire protocol, are cool in theory but prone to user error and frustration in practice. A typical user is not in a position to have established a prior secret with most of the people they need to make first contact with. Shared secrets also cannot be scaled to a group setting. Finally, shared secrets are often typed incorrectly (e.g. was the secret "Invisible Zebra" or "invisibleZebra"? This could be fixed with rules for secret normalization, but this is tricky and language specific). For the special case of advanced users with special security needs, however, a shared secret provides a much stronger validation than other methods of key binding (so long as the validation window is small). + +*Why not use Mail-back Verification?* If the provider distributes user keys, there is not any benefit to mail-back verification. The nicknym protocol could potentially benefit from a future enhancement to support mail-back for users on a non-cooperating legacy provider. However, at its best, mail-back is a very weak form of key validation. + +*Why not use Global Append-only Log?* Maybe we should, they are neat. However, current implementations are slow, resource intensive, and experimental (e.g. namecoin). + +*Why not use Nonverbal Feedback?* ZRTP can use non-verbal clues to establish secure identity because of the nature of a live phone call. This doesn't work for text only messaging. + +*Why not use the key fingerprint as the unique identifier?* This is the strategy taken by all systems for peer-to-peer messaging (e.g. retroshare, bitmessage, etc). Depending on the length of the fingerprint, this method is very secure. Essentially, this approach neatly solves the binding problem by collapsing the key and the identifier together as one. The problem, of course, is that this is not very user friendly. Users must either have pre-arranged some way to exchange fingerprints, or they must fall back to one of the other methods for verification (shared secret, WoT, etc). The friction associated with pre-arranged sharing of fingerprints can be reduced with technology, using QR-codes and hand held devices, for example. In the best case scenario, however, fingerprints as identifiers will always be much less user friendly than simple username@domain.org addresses. The motivating premise behind Nicknym is that when an identity system is hard to use, it is effectively compromised because too few people take the time to use it properly. + +Reference nickagent implementation +==================================================== + +https://github.com/leapcode/keymanager + +There is a reference nickagent implementation called "key manager" written in Python and integrated into the LEAP client. It uses Soledad to store its data. + +Public API +---------------------------- + +**refresh_keys()** + +updates the keys with fresh ones, as needed. + +**get_key(address, type)** + +returns a single public key for address. type is one of 'openpgp', 'otr', 'x509', or 'rsa'. + +**send_key(address, public_key, type)** + +authenticates with the appropriate provider and saves the public_key in the user database. + +Storage +-------------------------- + +Key manager uses Soledad for storage. GPGME, however, requires keys to be stored in keyrings, which are read from disk. + +For now, Key Manager deals with this by storing each key in its own keyring. In other words, every key is in a keyring with exactly 1 key, and this keyring is stored in a Soledad document.

Alice's Key Manager copies to disk her private key and bob's public key. The key manager gets these from Soledad, in the form of unitary Keyrings. +2.

With Nicknym, the user is able to think solely in terms of nickname, while still being able to communicate with a high degree of security (confidentiality, integrity, and authenticity). Essentially, Nicknym is a system for binding human-memorable nicknames to a cryptographic key via automatic discovery and automatic validation. + +Nicknym is a federated protocol: a Nicknym address is in the form `username@domain` just alike an email address and Nicknym includes both a client and a server component. Although the client can fall back to legacy methods of key discovery when needed, domains that run the Nicknym server component enjoy much stronger identity guarentees. + +Nicknym is key agnostic, and supports whatever public key information is available for an address (OpenPGP, OTR, X.509, RSA, etc). However, Nicknym enforces a strict one-to-one mapping of address to public key. + +**Why is Nicknym needed?** + +Existing forms of secure identity are deeply flawed. These systems rely on either a single trusted entity (e.g. Skype), a vulnerable Certificate Authority system (e.g. S/MIME), or key identifiers that are not human memorable (e.g. fingerprints used in OpenPGP, OTR, etc). When an identity system is hard to use, it is effectively compromised because too few people take the time to use it properly. + +The broken nature of existing identities systems (either in security or in usability) is especially troubling because identity remains a bedrock precondition for any message security: you cannot ensure confidentiality or integrity without confirming the authenticity of the other party. Nicknym is a protocol to solve this problem in a way that is backward compatible, easy for the user, and includes very strong authenticity. + +Goals +========================================== + +**High level goals** + +* Pseudo-anonymous and human friendly addresses in the form `username@domain`. +* Automatic discovery and validation of public keys associated with an address. +* The user should be able to use Nicknym without understanding anything about public/private keys or signatures. + +**Technical goals** + +* Wide utility: nicknym should be a general purpose protocol that can be used in wide variety of contexts. +* No revocation: instead of key revocation, support short lived keys that frequently and automatically refresh. +* Prevent dangerous actions: Nicknym should fail hard when there is a possibility of an attack. +* Minimize false positives: because Nicknym fails hard, we should minimize false positives where it fails incorrectly. +* Resistant to malicious actors: Nicknym should be externally auditable in order to assure service providers are not compromised or advertising bogus keys. +* Resistant to association analysis: Nicknym should not reveal to any actor or network observer a map of a user's associations. + +**Non-goals** + +* Nicknym does not try to create a decentralized peer-to-peer identity system. Nicknym is federated, akin to the way email is federated. + +The binding problem +============================================= + +Nicknym attempts to solve the problem of binding a human memorable identifier to a cryptographic key. If you have the identifier, you should be able to get the key with a high level of confidence, and vice versa. The goal is to have federated, human memorable, globally unique public keys. + +There are a number of established methods for binding identifier to key: + +* [X.509 Certificate Authority System](https://en.wikipedia.org/wiki/X.509) +* Trust on First Use (TOFU) +* Mail-back Verification +* [Web of Trust (WOT)](http://en.wikipedia.org/wiki/Web_of_trust) +* [DNSSEC](https://en.wikipedia.org/wiki/Dnssec) +* [Shared Secret](https://en.wikipedia.org/wiki/Socialist_millionaire) +* [Network Perspective](http://convergence.io/) +* Nonverbal Feedback (a la ZRTP) +* Global Append-only Log +* Key fingerprint as unique identifiers + +The methods differ widely, but they all try to solve the same general problem of proving that a person or organization is in control of a particular key. + +**Nicknym overview** + +Nicknym solves the binding problem by using a combination of methods, utilizing TOFU, X.509, Network Perspective, and additional methods we call "Provider Keys" and "Federated Web of Trust" (FWOT). + +1. Nicknym starts with TOFU of user keys, because it is easy to do and backward compatible with legacy providers. In TOFU, your client naively accept the key of another user when it first encounters it. When you accept a key via TOFU, you are making a bet that possible attackers against you did not have the foresight to specifically target you with a false key during discovery. +2. Next, we add X.509. For those providers that publish the public keys of their users, we require that these keys be fetched over validated TLS. This makes third party attacks against TOFU more difficult, but also places a lot of trust in the providers (and the Certificate Authorities). +3. Next, we add a simple form of Network Perspective where the client can ask one provider what key another provider is distributing. This allows a user's client to be able to audit their provider and keep them honest in an automated manner. If a service provider distributes bogus keys, their users and other providers will be quickly alerted to the problem. +4. Next, we add Provider Keys. If a service provider supports nicknym, the public keys of its users are additionally signed by a "provider key". If your client has the correct provider key, you no longer need to TOFU the keys of the provider's users. This has the benefit making it possible for a user to issue new keys, and to add support for very short-lived keys rather than trying to use key revocation. A service provider is much less likely to lose their private key or have it compromised, a significant problem with TOFU of user keys. +5. Finally, we add a Federated Web of Trust. The system works like this: each service provider is responsible for the due diligence of properly signing the keys of a few other providers, akin to the distributed web of trust model of OpenPGP, but with all the hard work of proper signature validation placed upon the service provider. When a user communicates with another party who happens to use a service provider that participates in the FWOT, the user's software will automatically trace a chain of signature from the other party's key, to their service provider, to the user's own service provider (with some possible intermediary signatures). This allows for identity that is verified through an end-to-end trust path from any user to any other user in a way that can be automated and is human memorable. Support for a FWOT allows us to bypass entirely X.509 Certificate Authorities, to gracefully handle short lived provider keys, and to handle emergency re-key events if a provider's key is lost. + +As we move down this list, each measure taken gets more complicated, requires more provider cooperation, and provides less additional benefit than the one before it. Nevertheless, each measure contributes some important benefit toward the goal of automatic binding of user identity to public key. + +**Questions** + +*Why not use WoT?* Most users are empirically unable to properly maintain a web of trust. The concepts are hard, it is easy to mess up the signing practice, most people default to TOFU anyway, and very few users use revocation properly.

These are both interesting standards for cryptographically proving identify, so why do we need something new? + +These protocols, and the poorly conceived OpenID Connect, are designed to address a fundamentally different problem: authenticating a user to a website. The problem of authenticating users to one another requires a different architecture entirely. There are some similarities, however, and in the long run a Nicknym provider could also be a WebID and Mozilla Persona provider. + +**STEED** + +[STEED](http://g10code.com/steed.html) is a proposal with very similar goals to Nicknym. In a nutshell, Nicknym basically looks very similar to STEED when the domain owner does not support Nicknym. STEED includes four main ideas: + +* trust upon first contact: Nicknym uses this as well, although this is the fallback mechanism when others fail. +* automatic key distribution and retrieval: Nicknym uses this as well, although we used HTTP for this instead of DNS. +* automatic key generation: Nicknym is designed specifically to support automatic key generation, but this is outside the scope of the Nicknym protocol and it is not required. +* opportunistic encryption: Again, Nicknym is designed to support opportunistic encryption, but does not require it. + +Additional differences include: + +* Nicknym is key agnostic: Nicknym does not make an assumption about what types of public keys a user wants to associate with their address. +* Nicknym is protocol agnostic: Nicknym can be used with SMTP, XMPP, SIP, etc. +* Nicknym relies on service provider adoption: With Nicknym, the strength of verification of public keys rests the degree to which a service provider adopts Nicknym. If a service provider does not support Nicknym, then effectively Nicknym opperates like STEED for that domain. + +**DANE** + +[DANE](https://datatracker.ietf.org/wg/dane/), and the specific proposal for [OpenPGP user keys using DANE](https://datatracker.ietf.org/doc/draft-wouters-dane-openpgp/), offer a standardized method for securely publishing and locating OpenPGP public keys in DNS. + +As noted above, DANE will be very cool if ever adopted widely, but user keys are probably not a good fit for DNSSEC, because of issues of observability of DNS queries and complexity on the server and client end. + +By relying on the central authority of the root DNS zone, and the authority of TLDs (many of which are of doubtful trustworthiness), DANE potentially suffers from problems of compromised or nefarious authorities. Because DNS queries are not secure, a single user is particularly vulnerable to MiTM attacks that rewrite all their DNS queries. Adopting an alternate DNS query system, like [DNSCurve](http://dnscurve.org/), [DNSCrypt](https://www.opendns.com/technology/dnscrypt/), an alternate HTTPS based API, or restricting DNS queries to a VPN, would go a long way to fix this problem, and would effectively turn any supporting DNS server into a network perspectives notary. Regardless, the other problems with using DANE for user keys remain. + +Nicknym protocol +============================== + +Definitions +------------------------- + +* **address**: A globally unique handle in the form user@domain (i.e. an email, SIP, or XMPP address). +* **provider**: A service provider that offers end-user services on a particular domain. +* **user key**: A public/private key pair associated with a user address. If not specified, "user key" refers to the public key. +* **provider key**: A public/private key pair owned by the provider. The address associated with this key is just the domain of the service provider. +* **validated key**: A key is "validated" if the nickagent has bound the user address to a public key. +* **nickagent**: Client side program that manages a user's contact list, the public keys they have encountered and validated, and the user's own key pairs. The nickagent may also expose an API for other local applications to query for a public key. +* **nickserver**: Server side daemon run by providers who support Nicknym. A nickserver is responsible for answering the question "what public key do you see for this address"? + +Nickserver requests +----------------------- + +A nickagent will attempt to discover the public key for a particular user address by contacting a nickserver. The nickserver returns JSON encoded key information in response to a simple HTTP request with a user's address. For example: + + curl -X POST -d address=alice@domain.org https://nicknym.domain.org:6425 + +* The port is always 6425. +* The HTTP verb may be POST or GET. +* The request must use TLS (see [Query security](#Query.security)). +* The query data should have a single field 'address'. +* For POST requests to nicknym.domain.org, the query data may be encrypted to the the public OpenPGP key nicknym@domain.org (see [Query security](#Query.security)). +* The request may include an "If-Modified-Since" header. In this case, the response might be "304 Not Modified". + +Requests may be local or foreign, and for user keys or for provider keys. + +* **local** requests are for information that the nickserver is authoritative. In other words, when the requested address is for the same domain that the nickserver is running on. +* **foreign** request are for information about other domains. +* **user key** requests are for addresses in the form "username@domain". +* **provider key** requests are for addresses in the form "domain". + +**Local, Provider Key request** + +For example: + + https://nicknym.domain.org:6425/?address=domain.org + +The response is the authoritative provider key for that domain. + +**Local, User Key request** + +For example: + + https://nicknym.domain.org:6425/?address=alice@domain.org + +The nickserver returns authoritative key information from the provider's own user database. Every public key returned for local requests must be signed by the provider's key. + +**Foreign, Provider Key request** + +For example: + + https://nicknym.domain.org:6425/?address=otherdomain.org + +1. First, check the nickserver's cache database of discovered keys. If the cache is not old, return this key. This step is skipped if the request is encrypted to the foreign provider's key. +2. Otherwise, fetch provider key from the provider's nickserver, cache the result, and return it. + +**Foreign, User Key request** + +For example: + + https://nicknym.domain.org:6425/?address=bob@otherdomain.org + +* First, check the nickserver's database cache of nicknyms. If the cache is not old, return the key information found in the cache. This step is skipped if the request is encrypted to a foreign provider key. +* Otherwise, attempt to contact a nickserver run by the provider of the requested address. If the nickserver exists, query that nickserver, cache the result, and return it in the response. +* Otherwise, fall back to querying existing SKS keyservers, cache the result and return it. +* Otherwise, return a 404 error. + +If the key returned for a foreign request contains multiple user addresses, they are all ignored by nicknym except for the user address specified in the request. + +Nickserver response +--------------------------------- + +The nickserver will respond with one of the following status codes: + +* "200 Success": found keys for this address, and the result is in the body of the response encoded as JSON. +* "304 Not Modified": if the request included an "If-Modified-Since" header and the keys in question have not been modified, the response will have status code 304. +* "404 Not Found": no keys were found for this address. +* "500 Error": An unknown error occurred. Details may be included in the body. + +Responses with status code 200 include a body text that is a JSON encoded map with a field "address" plus one or more of the following fields: "openpgp", "otr", "rsa", "ecc", "x509-client", "x509-server", "x509-ca". For example: + + { + "address": "alice@example.org", + "openpgp": "6VtcDgEKaHF64uk1c/crFhRHuFW9kTvgxAWAK01rXXjrxEa/aMOyXnVQuQINBEof...." + } + +Responses with status codes other than 200 include a body text that is a JSON encoded map with the following fields: "address", "status", and "message". For example: + + { + "address": "bob@otherdomain.org", + "status": 404, + "message": "Not Found" + } + +A nickserver response is always signed with a OpenPGP public signing key associated with the provider. Both successful AND unsuccessful responses are signed. Responses to successful local requests must be signed by the key associated with the address "nicknym@domain.org". Foreign requests and non-200 responses may alternately be signed with a key associated with the address nickserver@domain.org. This allows for user keys to be signed off-site and in advance, if they so choose. The signature is ASCII armored and appended to the JSON. + + { + "address": "alice@example.org", + "openpgp": "6VtcDgEKaHF64uk1c/crFhRHuFW9kTvgxAWAK01rXXjrxEa/aMOyXnVQuQINBEof...." + } + -----BEGIN PGP SIGNATURE----- + iQIcBAEBCgAGBQJRhWO+AAoJEIaItIgARAAl2IwP/24z9CjKjD0fd27pQs+r+e3h + p8KAYDbVac3+c3vm30DjHO/RKF4Zq6+sTAIkrFvXOwYJl9KgjMpQVV/voInjxATz + -----END PGP SIGNATURE----- + +If the data in the request was encrypted to the public key nicknym@domain.org, then the JSON response and signature are additionally encrypted to the symmetric key found in the request and returned base64 encoded. + +TBD: maybe we should just switch to a raw RSA or ECC signature. + +Query balancing +------------------------ + +A nickagent must choose what IP address to query by selecting randomly from among hosts that resolve from `nicknym.domain.org` (where `domain.org` is the domain name of the provider). + +If a host does not response, a nickagent must skip over it and attempt to contact another host in the pool. + +Query security +-------------------------- + +TLS is required for all nickserver queries. + +When querying https://nicknym.domain.org, nickagent must validate the TLS connection in one of four possible ways: + +1. Using a commercial CA certificate distributed with the host operating system. +2. Using DANE TLSA record to discover and validate the server certificate. +3. Using a seeded CA certificate (see [Discovering nickservers](#Discovering.nickservers)). +4. Using a custom self-signed CA certificate discovered for the domain, so long as the CA certificate was discovered via #1 or #2 or #3. Custom CA certificates may be discovered for a domain by making a provider key request of a nickserver (e.g. https://nicknym.known-domain.org/?address=new-domain.org). + +Optionally, a nickagent may make an encrypted query like so: + +0. Suppose the nickagent wants to make an encrypted query regarding the address alice@domain-x.org. +1. Nickagent discovers the public key for nicknym@domain-y.org. +2. The nickagent makes a POST request to a nickserver with two fields: address and ciphertext. +3. The address only contains the domain part of the address (unlike an unencrypted request). +4. The ciphertext field is encrypted to the public key for nicknym@domain-y.org. The corresponding cleartext contains the full address on the first line followed by randomly generated symmetric key on the second line. +5. If the request was local, the nickserver handles the request. If the request for foreign, the nickserver proxies the request to the domain specified in the address field. +6. When the request gets to the right nickserver, the body of the nickserver response is encrypted using using the symmetric key. The first line of the response specifies the cipher and mode used (allowed ciphers TBD). + +Comment: although it may seem excessive to encrypt both the request via TLS and the request body via OpenPGP, the reason for this is that many requests will not use OpenPGP. + +Automatic key validation +---------------------------------- + +A key is "validated" if the nickagent has bound the user address to a public key. + +Nicknym supports three different levels of key validation: + +* Level 3 - **path trusted**: A path of cryptographic signatures can be traced from a trusted key to the key under evaluation. By default, only the provider key from the user's provider is a "trusted key". +* Level 2 - **provider signed**: The key has been signed by a provider key for the same domain, but the provider key is not validated using a trust path (i.e. it is only registered) +* Level 1 - **registered**: The key has been encountered and saved, it has no signatures (that are meaningful to the nickagent). + +A nickagent will try to validate using the highest level possible. + +Automatic renewal +----------------------------- + +A validated public key is replaced with a new key when: + +* The new key is **path trusted** +* The new key is **provider signed**, but the old key is only **registered**. +* The new key has a later expiration, and the old key is only **registered** and will expire "soon" (exact time TBD). +* The agent discovers a new subkey, but the master signing key is unchanged. + +In all other cases, the new key is rejected. + +The nickagent will attempt to refresh a key by making request to a nickserver of its choice when a key is past 3/4 of its lifespan and again when it is about to expire. + +Nicknym encourages, but does not require, the use of short lived public keys, in the range of X to Y days. It is recommended that short lived keys are not uploaded to OpenPGP keyservers. + +Automatic invalidation +---------------------------- + +A key is invalidated if: + +* The old key has expired, and no new key can be discovered with equal or greater validation level. + +This means validation is a one way street: once a certain level of validation is established for a user address, no client should accept any future keys for that address with a lower level of validation. + +Discovering nickservers +-------------------------------- + +It is entirely up to the nickagent to decide what nickservers to query. If it wanted to, a nickagent could send all its requests to a single nickserver. + +However, nickagents should discover new nickservers and balance their queries to these nickservers for the purposes of availability, load balancing, network perspective, and hiding the user's association map. + +Whenever the nickagent is asked by a locally running application for a public key corresponding to an address on the domain `domain.org`, it may check to see if the host `nicknym.domain.org` exists. If the domain resolves, then the nickagent may add it to the pool of known nickservers. A nickagent should only perform this DNS check if it is able to do so over an encrypted tunnel. + +Additionally, a nickagent may be distributed with an initial list of "seed" nickservers. In this case, the nickagent is distributed with a copy of the CA certificate used to validate the TLS connection with each respective seed nickserver. + +Cross-provider signatures +---------------------------------- + +Nicknym does not support user signatures on user keys. There is no trust path from user to user. However, a service provider may sign the provider key of another provider. + +To be written. + +Auditing +---------------------------- + +In order to keep the user's provider from handing out bogus public keys, a nickagent should occasionally make foreign queries of the user's own address against nickservers run by third parties. The recommended frequency of these queries is once per day, at a random time during local waking hours. + +In order to prevent a nickserver from handing out bogus provider keys, a nickagent should query multiple nickservers before a provider key is registered or path trusted. + +Possible attacks: + +**Attack 1 - Intercept Outgoing:** + +* Attack: provider `A` signs an impostor key for provider `B` and distributes it to users of `A` (in order to intercept outgoing messages sent to `B`). +* Countermeasure: By querying multiple nickservers for the provider key of `B`, the nickagent can detect if provider `A` is attempting to distribute impostor keys. + +**Attack 2 - Intercept Incoming:** + +* Attack: provider `A` signs an impostor key for one of its own users, and distributes to users of provider `B` (in order to intercept incoming messages). +* Countermeasure: By querying for its own keys, a nickagent can detect if a provider is given out bogus keys for their addresses. + +**Attack 3 - Association Mapping:** + +* Attack: A provider tracks all the requests for key discovery in order to build a map of association. +* Countermeasure: By performing foreign key queries via third party nickservers, an agent can prevent any particular entity from tracking their queries. + +Known vulnerabilities +------------------------------------------ + +The nicknym protocol does not yet have a good solution for dealing with the following problems: + +* Enumeration attack: an attacker can enumerate the list of all users for a provider by simply querying every possible username combination. We have no defense against this, although it would surely take a while. +* DDoS attack: by their very nature, nickservers perform a bit of work for every request. Because of this, they are vulnerable to be overloaded by a a flood of bogus requests. +* Besmirch attack: a MitM attacker can sully the reputation of a provider by generating many bad responses (responses signed with the wrong key), thus leading other nickservers and nicknym agents to consider the provider compromised. + +Future enhancements +--------------------- + +**Additional discovery mechanisms** + +In addition to nickservers and SKS keyservers, there are two other potential methods for discovering public keys: + +* **Webfinger** includes a standard mechanism for distributing a user's public key via a simple HTTP request. This is very easy to implement on the server, and very easy to consume on the client side, but there are not many webfinger servers with public keys in the wild. +* **DNS** is used by multiple competing standards for key discovery. When and if one of these emerges predominate, Nicknym should attempt to use this method when available. + + +Reference nickagent implementation +==================================================== + +https://github.com/leapcode/keymanager + +There is a reference nickagent implementation called "key manager" written in Python and integrated into the LEAP client. It uses Soledad to store its data. + +Public API +---------------------------- + +**refresh_keys()** + +updates the keys with fresh ones, as needed. + +**get_key(address, type)** + +returns a single public key for address. type is one of 'openpgp', 'otr', 'x509', or 'rsa'. + +**send_key(address, public_key, type)** + +authenticates with the appropriate provider and saves the public_key in the user database. + +Storage +-------------------------- + +Key manager uses Soledad for storage. GPGME, however, requires keys to be stored in keyrings, which are read from disk. + +For now, Key Manager deals with this by storing each key in its own keyring. In other words, every key is in a keyring with exactly 1 key, and this keyring is stored in a Soledad document. To keep from confusing this keyring from a normal keyring, I will call it a 'unitary keyring'. + +Suppose Alice needs to communicate with Bob: + +1. Alice's Key Manager copies to disk her private key and bob's public key. The key manager gets these from Soledad, in the form of unitary Keyrings. +2. Client code uses GPGME, feeding it these temporary keyring files. +3. The keyrings are destroyed. + +TBD: how best to ensure destruction of the keyring files. + +An example Soledad document for an address: + + { + "address":"alice@example.org", + "keys": [ + { + "type": "opengpg" + "key": "binary blob", + "keyring": "binary blob", + "expires_on": "2014-01-01", + "validation": "provider_signed", + "first_seen_at": "2013-04-01 00:11:00", + "last_audited_at": "2013-04-02 12:00:00", + }, + { + "type": "otr" + "key": "binary blob", + "expires_on": "2014-01-01", + "validation": "registered", + "first_seen_at": "2013-04-01 00:11:00", + "last_audited_at": "2013-04-02 12:00:00", + } + ] + } + +Pseudocode +--------------------------- + +get_key + + # + # return a key for an address + # + function get_key(address, type) + if key for address exists in soledad database? + return key + else + fetch key from nickserver + save it in soledad + return key + end + end + +send_key + + # + # send the user's provider the user's key. this key will get signed by the provider, and replace any prior keys + # + function send_key(type) + if not authenticated: + error! + end + get (self.address, type) + send (key_data, type) to the provider + end + +refresh_keys + + # + # update the user's db of validated keys to see if there are changes. + # + function refresh_keys() + for each key in the soledad database (that should be checked?): + newkey = fetch_key_from_nickserver() + if key is about to expire and newkey complies with the renewal paramters: + replace key with newkey + else if fingerprint(key) != fingerprint(newkey): + freak out, something wrong is happening? :) + may be handle revokation, or try to get some voting for a given key and save that one (retrieve it through tor/vpn/etc and see what's the most found key or something like that. + else: + everything's cool for this key, continue + end + end + end + +private fetch_key_from_nickserver + + function fetch_key_from_nickserver(key) + randomly pick a subset of the available nickservers we know about + send a tcp request to each in this subset in parallel + first one that opens a successful socket is used, all the others are terminated immediately + make http request + parse json for the keys + return keys + end + + +Reference nickserver implementation +===================================================== + +https://github.com/leapcode/nickserver + +The reference nickserver is written in Ruby 1.9 and licensed GPLv3.

The client must be installed a user's device before they can access any LEAP services (except for user support via the web application). + +Desktop Client +-------------------------- + +LEAP Client for Linux, Windows, and Mac. + +Written in: Python + +Libraries used: QT, PyQT, OpenVPN, Sqlite, Sqlcipher, U1DB, OpenSSL, GPG. + +User interface: + +* First run wizard: walks the user through the bootstrap process when the client is first run (either registering a new user or authenticating as an existing user) +* Preferences panel: A mac system-preferences-like place to edit all the LEAP client settings (does not exist yet). +* Task bar: Show the status of LEAP services (connected? syncing?), and lets the user open the preferences panel. +* Update wizard: a dialog that shows the code update progress. + +Android Client +------------------------------ + +LEAP Client for Android. + +Written in: Java (possibly with with some Python in the future) + +Libraries used: sqlcipher, sqlite, bouncycastle, U1DB, OpenVPN. + +User interface: + +* Single button to connect or disconnect encrypted internet +* A notification drawer item indicating status of VPN +* A first run wizard + +Features (planned): + +* a sync provider to allow contacts and calendar data to be sync'ed via Soledad. +* eventually, match the desktop client in features. + + +LEAP Admin Tools +==================================== + +Platform Recipes +------------------------------ + +The LEAP platform recipes define an abstract service provider. It consists of puppet modules designed to work together to provide a system administrator everything they need to manage a service provider infrastructure that provides secure communication services. + +Typically, a system administrator will not need to modify the LEAP platform recipes, although they are free to fork and merge as desired. Most service providers using the LEAP platform will use the same platform recipes. + +The recipes are abstract. In order to configure settings for a particular service provider, a system administrator creates a provider instance. The platform recipes also include a base provider that provider instances inherit from. + +Provider Instance +---------------------------------- + +A "provider instance" is a directory tree (typically tracked in git) containing all the configurations for a service provider's infrastructure. A provider instance primarily consists of: + +* A configuration file for each server (node) in the provider's infrastructure (e.g. nodes/vpn1.json) +* A global configuration file for the provider (e.g. provider.json). +* Additional files, such as certificates and keys (e.g. files/nodes/vpn1/vpn1_ssh.pub). +* A pointer to the platform recipes (as defined in "Leapfile") + +A minimal provider instance directory looks like this: + + + └── bitmask # provider instance directory. + ├── common.json # settings common to all nodes. + ├── Leapfile # various settings for this instance. + ├── provider.json # global settings of the provider. + ├── files/ # keys, certificates, and other files. + ├── nodes/ # a directory for node configurations. + └── users/ # public key information for privileged sysadmins. + +A provider instance directory contains everything needed to manage all the servers that compose a provider's infrastructure. Because of this, you can use normal git development work-flow to manage your provider instance. + +Command line program +------------------------------- + +The command line program `leap` is used by sysadmins to manage everything about a service provider's infrastructure. Except when creating an new provider instance, `leap` is run from within the directory tree of a provider instance. + +The `leap` command line has many capabilities, including: + +* create an initial provider instance +* create, initialize, and deploy nodes (e.g. servers) +* manage keys and certificates +* query information about the node configurations + +Traditional system configuration automation systems, like puppet or chef, deploy changes to servers using a pull method. Each server pulls a manifest from a central master server and uses this to alter the state of the server. + +Instead, LEAP uses a masterless push method: The user runs 'leap deploy' from the provider instance directory on their desktop machine to push the changes out to every server (or a subset of servers). LEAP still uses puppet, but there is no central master server that each node must pull from. + +One other significant difference between LEAP and typical system automation is how interactions among servers are handled. Rather than store a central database of information about each server that can be queried when a recipe is applied, the `leap` command compiles static representation of all the information a particular server will need in order to apply the recipes. In compiling this static representation, `leap` can use arbitrary programming logic to query and manipulate information about other servers. + +These two approaches, masterless push and pre-compiled static configuration, allow the sysadmin to manage a set of LEAP servers using traditional software development techniques of branching and merging, to more easily create local testing environments using virtual servers, and to deploy without the added complexity and failure potential of a master server. + +Server-side Components +======================================= + +These are components where most of the code and logic runs on a server (as opposed to client-side components, where most of the code runs on the client). + +Databases +------------------------------------ + +All user data is stored using BigCouch, a decentralized and high-availability version of CouchDB. + +The databases are used by the different services and sometimes work as communication channels between the services. + +These are the databases we currently use: + +* customers -- payment information for the webapp +* identities -- alias information, written by the webapp, read by leap_mx and nickserver +* keycache -- used by the nickserver +* sessions -- web session persistance for the webapp +* shared -- used by soledad +* tickets -- help tickets issued in the webapp +* tokens -- created by the webapp on login, used by soledad to authenticate +* users -- user records used by the webapp including the authentication data +* user-...id... -- client-encrypted user data accessed from the client via soledad + +### Database Setup + +The main couch databases are initially created, seeded and updated when deploying the platform. + +The site_couchdb module contains the database description and security settings in `manifests/create_dbs.pp`. The design docs are seeded from the files in `files/designs/:db_name`. If these files change the next puppet deploy will update the databases accordingly. Both the webapp and soledad have scripts that will dump the required design docs so they can be included here. + +The per-user databases are created upon user registration by [Tapicero](https://leap.se/docs/design/tapicero). Tapicero also adds security and design documents. The design documents for per-user databases are stored in the [tapicero repository](https://github.com/leapcode/tapicero) in `designs`. Tapicero can be used to update existing user databases with new security settings and design documents. + +### BigCouch + +Like many NoSQL databases, BigCouch is inspired by [Amazon's Dynamo paper](http://www.allthingsdistributed.com/files/amazon-dynamo-sosp2007.pdf) and works by sharding each database among many servers using a circular ring hash. The number of shards might be greater than the number of servers, in which case each server would have multiple shards of the same database. Each server in the BigCouch cluster appears to contain the entire database, but actually it will just proxy the request to the actual database that has the content (if it does not have the document itself). + +Important BigCouch constants: + +* Q -- The number of shards over which a database will spread. +* N -- The number of redundant copies of each document. Default is 3. +* W -- The number of document copies that must be saved before document is 'written'. Default is 2. +* R -- The number of document copies that must be found before document is 'read'. Default is 2. +* Z -- The number of zones in the cluster. Each zone will have a complete copy of all the data. Default is 1. + +In LEAP, every service that needs to interact with the database runs a local HTTP load balancer that distributes database requests randomly to the BigCouch cluster. If a BigCouch node dies, the load balancer detects this and takes it out of rotation (this usage is typical of BigCouch installations). + +Web App +------------------------------ + +The LEAP Web App provides the following functions: + +* User registration and management +* Help tickets +* Client certificate renewal +* Webfinger access to user's public keys +* Email aliases and forwarding +* Localized and Customizable documentation + +Written in: Ruby, Rails. + +The Web App communicates with: + +* CouchDB is used for all data storage. +* Web browsers of users accessing the user interface in order to edit their settings or fill out help tickets. Additionally, admins may delete users. +* LEAP Clients access the web app's REST API in order to register new users, authenticate existing ones, and renew client certificates. +* tokens are stored upon successful authentication to allow the client to authenticate against other services + +Nickserver +------------------------------ + +Written in: Ruby +Libaries: EventMachine, GPG + +Nickserver is the opposite of a key server. A key server allows you to lookup keys, and the UIDs associated with a particular key. A nickserver allows you to query a particular 'nick' (e.g. username@example.org) and get back relevant public key information for that nick. + +Nickserver has the following properties: + +* Written in Ruby, licensed GPLv3 +* Lightweight and scalable (high concurrency, reasonable latency) +* Uses asynchronous network IO for both server and client connections (via EventMachine) +* Attempts to reply to queries using four different methods: + * Cached key in CouchDB + * Webfinger + * DNS + * HKP keyserver pool (https://hkps.pool.sks-keyservers.net) + +Why bother writing Nickserver instead of just using the existing HKP keyservers? + +* Keyservers are fundamentally different: Nickserver is a registry of 1:1 mapping from nick (uid) to public key. Keyservers are directories of public keys, which happen to have some uid information in the subkeys, but there is no way to query for an exact uid. +* Support clients: the goal is to provide clients with a cloud-based method of rapidly and easily converting nicks to keys. Client code can stay simple by pushing more of the work to the server. +* Enhancements over keyservers: the goal with Nickserver is to support future enhancements like webfinger, DNS key lookup, mail-back verification, network perspective, and fast distribution of short lived keys. +* Scalable: the goal is for a service that can handle many simultaneous requests very quickly with low memory consumption. + +Miscellaneous +------------------------------ + +A LEAP service provider might also run servers with the following services: + +* git -- private git repository hosting. +* Domain Name Server -- Authoritative name server for the provider's domain. +* Tapicero -- headless daemon that watches couch changes for new users and creates their databases + +Client-side Components +====================================== + +Most of the code and processing for these components happens on the client-side, although they all include some interaction with cloud services. + +Soledad +------------------------------ + +Soledad stands for "Synchronization Of Locally Encrypted Data Among Devices". On the client side, Soledad is responsible for client-encrypting user data, keeping it in sync with the copy in the cloud, and for providing local applications with a simple API for data storage. This "client-side Soledad" is essentially a local database that is kept in sync with the cloud. The "Soledad Server" is the cloud-based component that the client syncs with. + +Written in: Python (on desktops and servers), possibly Java (on android, not yet written). + +Libraries used: + +* Client-side: U1DB, Sqlite, Sqlcipher, GPG. +* Server: U1DB (forked), CouchDB. + +Client-side Soledad communicates with: + +* Other client application code, providing a storage API. +* Soledad Server via the U1DB synchronization protocol. + +Soledad Server communicates with: + +* LEAP Client via the U1DB synchronization protocol +* CouchDB or OpenStack Object Storage for backend storage. + +Client-side Soledad Notes: + +* Soledad is an modification of U1DB python reference implementation with changes to support client-side encryption and to replace sqlite with sqlcipher. +* Local data is stored on disk as an SQLite DB file(s) that is block-encrypted with sqlcipher (AES128). +* Before being synced to the server, a document is block-encrypted using a symmetric key composed from HMAC of the document id and a long secret (Soledad secret). +* Soledad secret is stored on-disk encrypted to the user's OpenPGP key. A copy is stored on the server as well. The same secret is shared among all the clients a user has activated. +* Soledad inherits these traits from U1DB: + * The storage API used by client code is similar to couchdb (schema-less document storage with indexes). + * Application code using Soledad is responsible for resolving sync conflicts. + +Secrets Manager +------------------------------ + +Not yet written. + +Written in: Python +Libraries used: GPG, GnuTLS + +Communicates with: Nickserver (cloud), Soledad (local). + +The Secrets Manager is a library that exposes to local client code an API for managing cryptographic material. It is responsible for: + +* private secrets: the user's private and public keys and certificates. +* public keys: discovering, registering, and trusting the public keys of other people. +* creation: creating keys as needed. +* renewal: fetch a new client certificate when the current one is about to expire. +* recovery: allow the user to recover their data if they lose everything except for a recovery code. +* crypto hardware: allow the user to unlock secrets via an OpenPGP smart card like cryptostick. + +**Example secrets** + +* A user's OpenPGP keypair +* The symmetric key used to encrypt local data (used by sqlcipher) +* The client certificate used to auth with OpenVPN gateway. +* The client certificate used to auth with the SMTP gateway. + +**Public key management** + +Some functionality of public key management: + +* Discover the public keys of recipients and senders via a Nickserver. +* "Register" the discovered keys, either using a federated path through the provider, directly, or via trust on first use (TOFU). For now, we will start initially with TOFU. +* Allow the user to choose between two competing keys when a recipient has multiple candidate keys. +* Allow the user to specify keys that should be not used. +* Allow the user to manually specify a user's public key. + +**Recovery** + +* Allow the user to generate and print out a recovery code. This creates a record on the server, in an anonymized way, that can be used to restore all the secrets stored by the key/secret manager and thus recover all your data. The provider should not know what recovery information maps to which user. +* Eventually, perhaps allow the user to specify other users who have the power to recover their lost secrets in the event that the user forgets their password. +* Allow the user to enter this recovery code when they have lost their username and password. If this is enabled, the user's private keys are stored in the cloud, albeit encrypted and anonymized. +* Give some users the option of full recovery via email reset by storing the user's password on the server. This would be a very low security option, but one that some users may wish to opt-in for. + +**Notes** + +* All secrets are stored in Soledad, except the secret to unlock Soledad storage. This way, all clients will have access to the same secrets. For some things, like validated public keys, this is exactly what we want. For other things, this could be a problem, and should be refined in future revisions. +* The current scheme is to store the user's private keys and private secrets in their Soledad storage.

Soledad aims to provide a cross-platform, cross-device, syncable document storage API, with the addition of client-side encryption of database replicas and document contents stored on the server. + +Key aspects of Soledad include: + +* **Client and server:** Soledad includes a server daemon and client application library. +* **Client-side encryption:** Soledad puts very little trust in the server by encrypting all data before it is synchronized to the server and by limiting ways in which the server can modify the user's data. +* **Local storage:** All data cached locally is stored in an encrypted database. +* **Document database:** An application using the Soledad client library is presented with a document-centric database API for storage and sync. Documents may be indexed, searched, and versioned. + +The current reference implementation of Soledad is written in Python and distributed under a GPLv3 license. + +Soledad is an acronym of "Synchronization of Locally Encrypted Documents Among Devices" and means "solitude" in Spanish. + +Goals +====================== + +**Security goals** + +* *Client-side encryption:* Before any data is synced to the cloud, it should be encrypted on the client device. +* *Encrypted local storage:* Any data cached in the client should be stored in an encrypted format. +* *Resistant to offline attacks:* Data stored on the server should be highly resistant to offline attacks (i.e. an attacker with a static copy of data stored on the server would have a very hard time discerning much from the data). +* *Resistant to online attacks:* Analysis of storing and retrieving data should not leak potentially sensitive information. +* *Resistance to data tampering:* The server should not be able to provide the client with old or bogus data for a document. + +**Synchronization goals** + +* *Consistency:* multiple clients should all get sync'ed with the same data. +* *Sync flag:* the ability to partially sync data. For example, so a mobile device doesn't need to sync all email attachments. +* *Multi-platform:* supports both desktop and mobile clients. +* *Quota:* the ability to identify how much storage space a user is taking up. +* *Scalable cloud:* distributed master-less storage on the cloud side, with no single point of failure. +* *Conflict resolution:* conflicts are flagged and handed off to the application logic to resolve. + +**Usability goals** + +* *Availability*: the user should always be able to access their data. +* *Recovery*: there should be a mechanism for a user to recover their data should they forget their password. + +**Known limitations** + +These are currently known limitations: + +* The server knows when the contents of a document have changed. +* There is no facility for sharing documents among multiple users. +* Soledad is not able to prevent server from withholding new documents or new revisions of a document. +* Deleted documents are never deleted, just emptied. Useful for security reasons, but could lead to DB bloat. + +**Non-goals** + +* Soledad is not for filesystem synchronization, storage or backup. It provides an API for application code to synchronize and store arbitrary schema-less JSON documents in one big flat document database. One could model a filesystem on top of Soledad, but it would be a bad fit. +* Soledad is not intended for decentralized peer-to-peer synchronization, although the underlying synchronization protocol does not require a server. Soledad takes a cloud approach in order to ensure that a client has quick access to an available copy of the data. + +Related software +================================== + +[Crypton](https://crypton.io/) - Similar goals to Soledad, but in javascript for HTML5 applications. + +[Mylar](https://github.com/strikeout/mylar) - Like Crypton, Mylar can be used to write secure HTML5 applications in javascript. Uniquely, it includes support for homomorphic encryption to allow server-side searches. + +[Firefox Sync](https://wiki.mozilla.org/Services/Sync) - A client-encrypted data sync from Mozilla, designed to securely synchronize bookmarks and other browser settings. + +[U1DB](http://pythonhosted.org/u1db/) - Similar API as Soledad, without encryption. + +Soledad protocol +=================================== + +Document API +----------------------------------- + +Soledad's document API is similar to the [API used in U1DB](http://pythonhosted.org/u1db/reference-implementation.html). + +* Document storage: `create_doc()`, `put_doc()`, `get_doc()`. +* Synchronization with the server replica: `sync()`. +* Document indexing and searching: `create_index()`, `list_indexes()`, `get_from_index()`, `delete_index()`. +* Document conflict resolution: `get_doc_conflicts()`, `resolve_doc()`. + +For example, create a document, modify it and sync: + + sol.create_doc({'my': 'doc'}, doc_id='mydoc') + doc = sol.get_doc('mydoc') + doc.content = {'new': 'content'} + sol.put_doc(doc) + sol.sync() + +Storage secret +----------------------------------- + +The `storage_secret` is a long, randomly generated key used to derive encryption keys for both the documents stored on the server and the local replica of these documents. The `storage_secret` is block encrypted using a key derived from the user's password and saved locally on disk in a file called `<user_uid>.secret`, which contains a JSON structure that looks like this: + + { + "storage_secrets": { + "<secret_id>": { + "kdf": "scrypt", + "kdf_salt": "<b64 repr of salt>", + "kdf_length": <key_length>, + "cipher": "aes256", + "length": <secret_length>, + "secret": "<encrypted storage_secret>", + } + } + 'kdf': 'scrypt', + 'kdf_salt': '<b64 repr of salt>', + 'kdf_length: <key length> + } + +The `storage_secrets` entry is a map that stores information about available storage keys. Currently, Soledad uses only one storage key per provider, but this may change in the future. + +The following fields are stored for one storage key: + +* `secret_id`: a handle used to refer to a particular `storage_secret` and equal to `sha256(storage_secret)`. +* `kdf`: the key derivation function to use. Only scrypt is currently supported. +* `kdf_salt`: the salt used in the kdf. The salt for scrypt is not random, but encodes important parameters like the limits for time and memory. +* `kdf_length`: the length of the derived key resulting from the kdf. +* `cipher`: what cipher to use to encrypt `storage_secret`. It must match `kdf_length` (i.e. the length of the derived_key). +* `length`: the length of `storage_secret`, when not encrypted. +* `secret`: the encrypted `storage_secret`, created by `sym_encrypt(cipher, storage_secret, derived_key)` (base64 encoded). + +Other variables: + +* `derived_key` is equal to `kdf(user_password, kdf_salt, kdf_length)`. +* `storage_secret` is equal to `sym_decrypt(cipher, secret, derived_key)`. + +When a client application first wants to use Soledad, it must provide the user's password to unlock the `storage_secret`: + + from leap.soledad.client import Soledad + sol = Soledad( + uuid='<user_uid>', + passphrase='<user_passphrase>', + secrets_path='~/.config/leap/soledad/<user_uid>.secret', + local_db_path='~/.config/leap/soledad/<user_uid>.db', + server_url='https://<soledad_server_url>', + cert_file='~/.config/leap/providers/<provider>/keys/ca/cacert.pem', + auth_token='<auth_token>', + secret_id='<secret_id>') # optional argument + + +Currently, the `storage_secret` is shared among all devices with access to a particular user's Soledad database. See [Recovery and bootstrap](#Recovery.and.bootstrap) for how the `storage_secret` is initially installed on a device. + +We don't use the `derived_key` as the `storage_secret` because we want the user to be able to change their password without needing to re-key. + +Document encryption +------------------------ + +Before a JSON document is synced with the server, it is transformed into a document that looks like this: + + { + "_enc_json": "<ciphertext>", + "_enc_scheme": "symkey", + "_enc_method": "aes256ctr", + "_enc_iv": "<initialization_vector>", + "_mac": "<auth_mac>", + "_mac_method": "hmac" + } + +About these fields: + +* `_enc_json`: The original JSON document, encrypted and hex encoded. Calculated as: + * `doc_key = hmac(storage_secret[MAC_KEY_LENGTH:], doc_id)` + * `ciphertext = hex(sym_encrypt(cipher, content, doc_key))` +* `_enc_scheme`: Information about the encryption scheme used to encrypt this document (i.e.`pubkey`, `symkey` or `none`). +* `_enc_method`: Information about the block cipher that is used to encrypt this document. +* `_mac`: A MAC to prevent the server from tampering with stored documents. Calculated as: + * `mac_key = hmac(storage_secret[:MAC_KEY_LENGTH], doc_id)` + * `_mac = hmac(doc_id|rev|ciphertext|_enc_scheme|_enc_method|_enc_iv, mac_key)` +* `_mac_method`: The method used to calculate the mac above (currently hmac). + +Other variables: + +* `doc_key`: This value is unique for every document and only kept in memory. We use `doc_key` instead of simply `storage_secret` in order to hinder possible derivation of `storage_secret` by the server. Every `doc_id` is unique. +* `content`: equal to `sym_decrypt(cipher, ciphertext, doc_key)`. + +When receiving a document with the above structure from the server, Soledad client will first verify that `_mac` is correct, then decrypt the `_enc_json` to find `content`, which it saves as a cleartext document in the local encrypted database replica. + +The document MAC includes the document revision and the client will refuse to download a new document if the document does not include a higher revision. In this way, the server cannot rollback a document to an older revision. The server also cannot delete a document, since document deletion is handled by removing the document contents, marking it as deleted, and incrementing the revision. However, a server can withhold from the client new documents and new revisions of a document (including withholding document deletion). + +The currently supported encryption ciphers are AES256 (CTR mode) and XSalsa20. The currently supported MAC method is HMAC with SHA256. + +Document synchronization +----------------------------------- + +Soledad follows the U1DB synchronization protocol, with some changes: + +* Add the ability to flag some documents so they are not synchronized by default (not fully supported yet). +* Refuse to synchronize a document if it is encrypted and the MAC is incorrect. +* Always use `https://<soledad_server_url>/user-<user_uid>` as the synchronization URL. + + + doc = sol.create_doc({'some': 'data'}) + doc.syncable = False + sol.sync() # will not send the above document to the server! + +Document IDs +-------------------- + +Like U1DB, Soledad allows the programmer to use whatever ID they choose for each document. However, it is best practice to let the library choose random IDs for each document so as to ensure you don't leak information. In other words, leave the second argument to `create_doc()` empty. + +Re-keying +----------- + +Sometimes there is a need to change the `storage_secret`. Rather then re-encrypt every document, Soledad implements a system called "lazy revocation" where a new `storage_secret` is generated and used for all subsequent encryption. The old `storage_secret` is still retained and used when decrypting older documents that have not yet been re-encrypted with the new `storage_secret`. + +Authentication +----------------------- + +Unlike U1DB, Soledad only supports token authentication and does not support OAuth. Soledad itself does not handle authentication. Instead, this job is handled by a thin HTTP WSGI middleware layer running in front of the Soledad server daemon, which retrieves valid tokens from a certain shared database and compares with the user-provided token. How the session token is obtained is beyond the scope of Soledad. + +Bootstrap and recovery +------------------------------------------ + +Because documents stored on the server's database replica have their contents encrypted with keys based on the `storage_secret`, initial synchronizations of newly configured provider accounts are only possible if the secret is transferred from one device to another. Thus, installation of Soledad in a new device or account recovery after data loss is only possible if specific recovery data has previously been exported and either stored on the provider or imported on a new device. + +Soledad may export a recovery document containing recovery data, which may be password-encrypted and stored in the server, or stored in a safe environment in order to be later imported into a new Soledad installation. + +**Recovery document** + +An example recovery document: + + { + 'storage_secrets': { + '<secret_id>': { + 'kdf': 'scrypt', + 'kdf_salt': '<b64 repr of salt>' + 'kdf_length': <key length> + 'cipher': 'aes256', + 'length': <secret length>, + 'secret': '<encrypted storage_secret>', + }, + }, + 'kdf': 'scrypt', + 'kdf_salt': '<b64 repr of salt>', + 'kdf_length: <key length>, + '_mac_method': 'hmac', + '_mac': '<mac>' + } + +About these fields: + +* `secret_id`: a handle used to refer to a particular `storage_secret` and equal to `sha256(storage_secret)`. +* `kdf`: the key derivation function to use. Only scrypt is currently supported. +* `kdf_salt`: the salt used in the kdf. The salt for scrypt is not random, but encodes important parameters like the limits for time and memory. +* `kdf_length`: the length of the derived key resulting from the kdf. +* `length`: the length of the secret. +* `secret`: the encrypted `storage_secret`. +* `cipher`: what cipher to use to encrypt `secret`. It must match `kdf_length` (i.e. the length of the `derived_key`). +* `_mac_method`: The method used to calculate the mac above (currently hmac). +* `_mac`: Defined as `hmac(doc_id|rev|ciphertext, doc_key)`. The purpose of this field is to prevent the server from tampering with the stored documents. + +Currently, scrypt parameters are: + + N (CPU/memory cost parameter) = 2^14 = 16384 + p (paralelization parameter) = 1 + r (length of block mixed by SMix()) = 8 + dkLen (length of derived key) = 32 bytes = 256 bits + +Other fields we might want to include in the future: + +* `expires_on`: the month in which this recovery document should be purged from the database. The server may choose to purge documents before their expiration, but it should not let them linger after it. +* `soledad`: the encrypted `soledad.json`, created by `sym_encrypt(cipher, contents(soledad.json), derived_key)` (base64 encoded). +* `reset_token`: an optional encrypted password reset token, if supported by the server, created by `sym_encrypt(cipher, password_reset_token, derived_key)` (base64 encoded). The purpose of the reset token is to allow recovery using the recovery code even if the user has forgotten their password. It is only applicable if using recovery code method. + +**Recovery database** + +In order to support easy recovery, the Soledad client stores a recovery document in a special recovery database. This database is shared among all users. + +The recovery database supports two functions: + +* `get_doc(doc_id)` +* `put_doc(doc_id, recovery_document_content)` + +Anyone may preform an unauthenticated `get_doc` request. To mitigate the potential attacks, the response to queries of the discovery database must have a long delay of X seconds. Also, the `doc_id` is very long (see below). + +Although the database is shared, the user must authenticate via the normal means before they are allowed to put a recovery document. Because of this, a nefarious server might potentially record which user corresponds to which recovery documents. A well behaved server, however, will not retain this information. If the server supports authentication via blind signatures, then this will not be an issue. + + +**Recovery code (yet to be implemented)** + +We intend to offer data recovery by specifying username and a recovery code. The choice of type of recovery (using password or a recovery code) must be made in advance of attempting recovery (e.g. at some point after the user has Soledad successfully running on a device). + +About the optional recovery code: + +* The recovery code should be randomly generated, at least 16 characters in length, and contain all lowercase letters (to make it sane to type into mobile devices). +* The recovery code is not stored by Soledad. When the user needs to bootstrap a new device, a new code is generated. To be used for actual recovery, a user will need to record their recovery code by printing it out or writing it down. +* The recovery code is independent of the password. In other words, if a recovery code is generated, then a user changes their password, the recovery code is still be sufficient to restore a user's account even if the user has lost the password. This feature is dependent on the server supporting a password reset token. Also, generating a new recovery code does not affect the password. +* When a new recovery code is created, and new recovery document must be pushed to the recovery database. A code should not be shown to the user before this happens. +* The recovery code expires when the recovery database record expires (see below). + +The purpose of the recovery code is to prevent a compromised or nefarious Soledad service provider from decrypting a user's storage. The benefit of a recovery code over the user password is that the password has a greater opportunity to be compromised by the server. Even if authentication is performed via Secure Remote Password, the server may still perform a brute force attack to derive the password. + +Reference implementation of client +=================================== + +https://github.com/leapcode/soledad + +Dependencies: + +* [U1DB](https://launchpad.net/u1db) provides an API and protocol for synchronized databases of JSON documents. +* [SQLCipher](http://sqlcipher.net/) provides a block-encrypted SQLite database used for local storage. +* python-gnupg +* scrypt +* pycryptopp + +Local storage +-------------------------- + +U1DB reference implementation in Python has an SQLite backend that implements the object store API over a common SQLite database residing in a local file. To allow for encrypted local storage, Soledad adds a SQLCipher backend, built on top of U1DB's SQLite backend, which adds [SQLCipher API](http://sqlcipher.net/sqlcipher-api/) to U1DB. + +**Responsibilities** + +The SQLCipher backend is responsible for: + +* Providing the SQLCipher API for U1DB (`PRAGMA` statements that control encryption parameters). +* Guaranteeing that the local database used for storage is indeed encrypted. +* Guaranteeing secure synchronization: + * All data being sent to a remote replica is encrypted with a symmetric key before being sent. + * Ensure that data received from remote replica is indeed encrypted to a symmetric key when it arrives, and then that it is decrypted before being included in the local database replica. +* Correctly representing and handling new Document properties (e.g. the `sync` flag). + +Part of the Soledad `storage_key` is used directly as the key for the SQLCipher encryption layer. SQLCipher supports the use of a raw 256 bit keys if provided as a 64 character hex string. This will skip the key derivation step (PBKDF2), which is redundant in our case. For example: + + sqlite> PRAGMA key = "x'2DD29CA851E7B56E4697B0E1F08507293D761A05CE4D1B628663F411A8086D99'"; + +**Classes** + +SQLCipher backend classes: + +* `SQLCipherDatabase`: An extension of `SQLitePartialExpandDatabase` used by Soledad Client to store data locally using SQLCipher. It implements the following: + * Need of a password to instantiate the db. + * Verify if the db instance is indeed encrypted. + * Use a LeapSyncTarget for encrypting content before synchronizing over HTTP. + * "Syncable" option for documents (users can mark documents as not syncable, so they do not propagate to the server). + +Encrypted synchronization target +-------------------------------------------------- + +To allow for database synchronization among devices, Soledad uses the following conventions: + +* Centralized synchronization scheme: Soledad clients always sync with a server, and never between themselves. +* The server stores its database in a CouchDB database using a REST API over HTTP. +* All data sent to the server is encrypted with a symmetric secret before being sent. Note that this ensures all data received by the server and stored in the CouchDB database has been encrypted by the client. +* All data received from the server is validated as being an encrypted blob, and then is decrypted before being stored in local database. Note that the local database provides a new encryption layer for the data through SQLCipher. + +**Responsibilities** + +Provide sync between local and remote replicas: + +* Encrypt outgoing content. +* Decrypt incoming content. + +**Classes** + +Synchronization-related classes: + +* `SoledadSyncTarget`: an extension of `HTTPSyncTarget` modified to encrypt documents' content before sending them to the network and to have more control of the syncing process. + +Reference implementation of server +====================================================== + +https://github.com/leapcode/soledad + +Dependencies: + +* [CouchDB](https://couchdb.apache.org/] for server storage, via [python client library](https://pypi.python.org/pypi/CouchDB/0.8). +* [Twisted](http://twistedmatrix.com/trac/) to run the WSGI application. +* scrypt +* pycryptopp +* PyOpenSSL + +CouchDB backend +------------------------------- + +In the server side, Soledad stores its database replicas in CouchDB servers. Soledad's CouchDB backend implementation is built on top of U1DB's `CommonBackend`, and stores and fetches data using a remote CouchDB server. It lacks indexing first because we don't need that functionality on server side, but also because if not very well done, it could lack sensitive information about document's contents. + +CouchDB backend is responsible for: + +* Initializing and maintaining the following U1DB replica data in the database: + * Transaction log. + * Conflict log. + * Synchronization log. +* Mapping the U1DB API to CouchDB API. + +**Classes** + +* `CouchDatabase`: A backend used by Soledad Server to store data in CouchDB. +* `CouchSyncTarget`: Just a target for syncing with Couch database. +* `CouchServerState`: Interface of the WSGI server with the CouchDB backend. + +WSGI Server +----------------------------------------- + +The U1DB server reference implementation provides for an HTTP API backed by SQLite databases. Soledad extends this with token-based auth HTTP access to CouchDB databases. + +* Soledad makes use of `twistd` from Twisted API to serve its WSGI application. +* Authentication is done by means of a token. +* Soledad implements a WSGI middleware in server side that: + * Uses the provided token to verify read and write access to each user's private databases and write access to the shared recovery database. + * Allows reading from the shared remote recovery database. + * Uses CouchDB as its backend. + +**Classes** + +* `SoledadAuthMiddleware`: implements the WSGI middleware with token based auth as described before. +* `SoledadApp`: The WSGI application. For now, not different from `u1db.remote.http_app.HTTPApp`. + +**Authentication** + +Soledad Server authentication middleware controls access to user's private databases and to the shared recovery database. Soledad client provides a token for Soledad server that can check the validity of this token for this user's session by querying a certain database. + +A valid token for this user's session is required for: + +* Read and write access to this user's database. +* Read and write access to the shared recovery database. + +Tests +=================== + +To be sure the new implemented backends work correctly, we included in Soledad the U1DB tests that are relevant for the new pieces of code (backends, document, http(s) and sync tests).

It also uses OpenSSL and pycryptopp for the cryptography bits. So the possibilities for porting Soledad to Android are: Implement it in pure C and use cryptopp (since it's what pycryptopp is using underneath), do an pure Java implementation or try to run the Python code we are already using. It would be reasonable to not have the most fast implementation at first if running our Python code is possible and would shorten the development times. + +### Port Keymanager to Android +* Dependencies: Soledad for Android +* Contact: drebs, chiiph +* Difficulty: Medium +* Description: The way we try to solve the key distribution problem is by having a NickServer and handling key logic through what we call the KeyManager.

Starting a node for the first time will spin up a virtual machine. The first time you do this will take some time because it will need to download a VM image (about 700mb). After you've downloaded the base image, you will not need to download it again, and instead you will re-use the downloaded image (until you need to update the image). + +NOTE: Many people have difficulties getting Vagrant working.

For more information about a specific + VM, run `vagrant status NAME`. + +Stopping machines +----------------- + +It is not recommended that you leave your virtual machines running when you are not using them. They consume memory and other resources! To stop your machines, simply do the following: + + $ leap local stop web1 db1 + +Connecting to machines +---------------------- + +You can connect to your local nodes just like you do with normal LEAP nodes, by running 'leap ssh node'. + +However, if you cannot connect to your local node, because the networking is not setup properly, or you have deployed a firewall that locks you out, you may need to access the graphical console. + +In order to do that, you will need to configure Vagrant to launch a graphical console and then you can login as root there to diagnose the networking problem. To do this, add the following to your $HOME/.leaprc: + + @custom_vagrant_vm_line = 'config.vm.provider "virtualbox" do |v| + v.gui = true + end' + +and then start, or restart, your local Vagrant node. You should get a VirtualBox graphical interface presented to you showing you the bootup and eventually the login. + +Snapshotting machines +--------------------- + +A very useful feature of local Vagrant development nodes is the ability to snapshot the current state and then revert to that when you need. + +For example, perhaps the base image is a little bit out of date and you want to get the packages updated to the latest before continuing. You can do that simply by starting the node, connecting to it and updating the packages and then snapshotting the node: + + $ leap local start web1 + $ leap ssh web1 + web1# apt-get -u dist-upgrade + web1# exit + $ leap local save web1 + +Now you can deploy to web1 and if you decide you want to revert to the state before deployment, you simply have to reset the node to your previous save: + + $ leap local reset web1 + +More information +---------------- + +See `leap help local` for a complete list of local-only commands and how they can be used. + + +Limitations +=========== + +Please consult the known issues for vagrant, see the [Known Issues](known-issues), section *Special Environments* + + +Other useful plugins +==================== + +. The vagrant-cachier (plugin http://fgrehm.viewdocs.io/vagrant-cachier/) lets you cache .deb packages on your hosts so they are not downloaded by multiple machines over and over again, after resetting to a previous state. + +Troubleshooting Vagrant +======================= + +To troubleshoot vagrant issues, try going through these steps: + +* Try plain vagrant using the [Getting started guide](http://docs.vagrantup.com/v2/getting-started/index.html). +* If that fails, make sure that you can run virtual machines (VMs) in plain virtualbox (Virtualbox GUI or VBoxHeadless). + We don't suggest a sepecial howto for that, [this one](http://www.thegeekstuff.com/2012/02/virtualbox-install-create-vm/) seems pretty decent, or you follow the [Oracale Virtualbox User Manual](http://www.virtualbox.org/manual/UserManual.html). There's also specific documentation for [Debian](https://wiki.debian.org/VirtualBox) and for [Ubuntu](https://help.ubuntu.com/community/VirtualBox). If you succeeded, try again if you now can start vagrant nodes using plain vagrant (see first step). +* If plain vagrant works for you, you're very close to using vagrant with leap !

Most of the time it will be customized and deployed in that context. This section describes the integration of LEAP web in the wider framework. The Development section focusses on development of LEAP web itself. + +Configuration & Customization +------------------------------ + +The customization of the webapp for a leap provider happens via two means: + * configuration settings in services/webapp.json + * custom files in files/webapp + +### Configuration Settings + +The webapp ships with a fairly large set of default settings for all environments. They are stored in config/defaults.yml. During deploy the platform creates config/config.yml from the settings in services/webapp.json. These settings will overwrite the defaults. + +### Custom Files + +Any file placed in files/webapp in the providers repository will overwrite the content of config/customization in the webapp. These files will override files of the same name. + +This mechanism allows customizing basically all aspects of the webapp. +See files/webapp/README.md in the providers repository for more. + +### Provider Information ### + +The leap client fetches provider information via json files from the server. The platform prepares that information and stores it in the webapp in public/1/config/*.json. (1 being the current API version). + +Provider Documentation +------------- + +LEAP web already comes with a bit of user documentation. It mostly resides in app/views/pages and thus can be overwritten by adding files to files/webapp/views/pages in the provider repository. You probably want to add your own Terms of Services and Privacy Policy here. +The webapp will render haml, erb and markdown templates and pick translated content from localized files such as privacy_policy.es.md. In order to add or remove languages you have to modify the available_locales setting in the config. (See Configuration Settings above) + +Development +=========== + +Installation +--------------------------- + +Typically, this application is installed automatically as part of the LEAP Platform. To install it manually for testing or development, follow these instructions: + +### TL;DR ### + +Install git, ruby 1.9, rubygems and couchdb on your system.

Its goal is to make it as painless as possible for sysadmins to deploy and maintain a service provider's infrastructure for secure communication. + +The LEAP Platform consists of three parts, detailed below: + +1. The platform recipes. +2. The provider instance. +3. The `leap` command line tool. + +The platform recipes +-------------------- + +The LEAP platform recipes define an abstract service provider. It is a set of [Puppet](https://puppetlabs.com/puppet/puppet-open-source/) modules designed to work together to provide to sysadmins everything they need to manage a service provider infrastructure that provides secure communication services. + +LEAP maintains a repository of platform recipes, which typically do not need to be modified, although it can be forked and merged as desired. Most service providers using the LEAP platform can use the same set of platform recipes. + +As these recipes consist in abstract definitions, in order to configure settings for a particular service provider a system administrator has to create a provider instance (see below). + +LEAP's platform recipes are distributed as a git repository: `https://leap.se/git/leap_platform` + +The provider instance +--------------------- + +A provider instance is a directory tree (typically tracked in git) containing all the configurations for a service provider's infrastructure. A provider instance primarily consists of: + +* A pointer to the platform recipes. +* A global configuration file for the provider. +* A configuration file for each server (node) in the provider's infrastructure. +* Additional files, such as certificates and keys. + +A minimal provider instance directory looks like this: + + └── bitmask # provider instance directory. + ├── Leapfile # settings for the `leap` command line tool. + ├── provider.json # global settings of the provider. + ├── common.json # settings common to all nodes. + ├── nodes/ # a directory for node configurations. + ├── files/ # keys, certificates, and other files. + └── users/ # public key information for privileged sysadmins. + + +A provider instance directory contains everything needed to manage all the servers that compose a provider's infrastructure. Because of this, any versioning tool and development work-flow can be used to manage your provider instance. + +The `leap` command line tool +---------------------------- + +The `leap` [command line tool](commands) is used by sysadmins to manage everything about a service provider's infrastructure. Except when creating an new provider instance, `leap` is run from within the directory tree of a provider instance. + +The `leap` command line has many capabilities, including: + +* Create, initialize, and deploy nodes. +* Manage keys and certificates. +* Query information about the node configurations. + +Traditional system configuration automation systems, like [Puppet](https://puppetlabs.com/puppet/puppet-open-source/) or [Chef](http://www.opscode.com/chef/), deploy changes to servers using a pull method. Each server pulls a manifest from a central master server and uses this to alter the state of the server. + +Instead, the `leap` tool uses a masterless push method: The sysadmin runs `leap deploy` from the provider instance directory on their desktop machine to push the changes out to every server (or a subset of servers). LEAP still uses Puppet, but there is no central master server that each node must pull from. + +One other significant difference between LEAP and typical system automation is how interactions among servers are handled. Rather than store a central database of information about each server that can be queried when a recipe is applied, the `leap` command compiles static representation of all the information a particular server will need in order to apply the recipes. In compiling this static representation, `leap` can use arbitrary programming logic to query and manipulate information about other servers. + +These two approaches, masterless push and pre-compiled static configuration, allow the sysadmin to manage a set of LEAP servers using traditional software development techniques of branching and merging, to more easily create local testing environments using virtual servers, and to deploy without the added complexity and failure potential of a master server. + +The `leap` command line tool is distributed as a git repository: `https://leap.se/git/leap_cli`. It can be installed with `sudo gem install leap_cli`. + +Getting started +---------------------------------- + +We recommend reading the platform documentation in the following order: + +1.

This person will have root access to all the servers. + + +Leapfile +------------------------------------------- + +A `Leapfile` defines options for the `leap` command and lives at the root of your provider directory. `Leapfile` is evaluated as ruby, so you can include whatever weird logic you want in this file. In particular, there are several variables you can set that modify the behavior of leap. For example: + + @platform_directory_path = '../leap_platform' + @log = '/var/log/leap.log' + +Additionally, you can create a `~/.leaprc` file that is loaded after `Leapfile` and is evaluated the same way. + +Platform options: + +* `@platform_directory_path` (required). This must be set to the path where `leap_platform` lives. The path may be relative. + +Vagrant options: + +* `@vagrant_network`. Allows you to override the default network used for local nodes. It should include a netmask like `@vagrant_network = '10.0.0.0/24'`. +* `@custom_vagrant_vm_line`. Insert arbitrary text into the auto-generated Vagrantfile. For example, `@custom_vagrant_vm_line = "config.vm.boot_mode = :gui"`. + +Logging options: + +* `@log`. If set, all command invocation and results are logged to the specified file. This is the same as the switch `--log FILE`, except that the command line switch will override the value in the Leapfile. + + +JSON format +------------------------------------------- + +All configuration files, other than `Leapfile`, are in the JSON format. For example: + + { + "key1": "value1", + "key2": "value2" + } + +Keys should match `/[a-z0-9_]/` + +Unlike traditional JSON, comments are allowed. If the first non-whitespace characters are `//` then the line is treated as a comment. + + // this is a comment + { + // this is a comment + "key": "value" // this is an error + } + +Options in the configuration files might be nested hashes, arrays, numbers, strings, or boolean. Numbers and boolean values should **not** be quoted. For example: + + { + "openvpn": { + "ip_address": "1.1.1.1", + "protocols": ["tcp", "udp"], + "ports": [80, 53], + "options": { + "public_ip": false, + "adblock": true + } + } + } + +If the value string is prefixed with an '=' character, the result is evaluated as ruby. For example: + + { + "domain": { + "public": "domain.org" + } + "api_domain": "= 'api.' + domain.public" + } + +In this case, the property "api_domain" will be set to "api.domain.org". So long as you do not create unresolvable circular dependencies, you can reference other properties in evaluated ruby that are themselves evaluated ruby. + +See "Macros" below for information on the special macros available to the evaluated ruby. + +TIP: In rare cases, you might want to force the evaluation of a value to happen in a later pass after most of the other properties have been evaluated. To do this, prefix the value string with "=>" instead of "=". + +Node inheritance +---------------------------------------- + +Every node inherits from common.json and also any of the services or tags attached to the node. Additionally, the `leap_platform` contains a directory `provider_base` that defines the default values for tags, services and common.json. + +Suppose you have a node configuration for `bitmask/nodes/willamette.json` like so: + + { + "services": "webapp", + "tags": ["production", "northwest-us"], + "ip_address": "1.1.1.1" + } + +This node will have hostname "willamette" and it will inherit from the following files (in this order): + +1. common.json + - load defaults: `provider_base/common.json` + - load provider: `bitmask/common.json` +2. service "webapp" + - load defaults: `provider_base/services/webapp.json` + - load provider: `bitmask/services/webapp.json` +3. tag "production" + - load defaults: `provider_base/tags/production.json` + - load provider: `bitmask/tags/production.json` +4. tag "northwest-us" + - load: `bitmask/tags/northwest-us.json` +5. finally, load node "willamette" + - load: `bitmask/nodes/willamette.json` + +The `provider_base` directory is under the `leap_platform` specified in the file `Leapfile`. + +To see all the variables a node has inherited, you could run `leap inspect willamette`. + +Common configuration options +---------------------------------------- + +You can use the command `leap inspect` to see what options are available for a provider, node, service, or tag configuration. For example: + +* `leap inspect common` -- show the options inherited by all nodes. +* `leap inspect --base common` -- show the common.json from `provider_base` without the local `common.json` inheritance applied. +* `leap inspect webapp` -- show all the options available for the service `webapp`. + +Here are some of the more important options you should be aware of: + +* `ip_address` -- Required for all nodes, no default. +* `ssh.port` -- The SSH port you want the node's OpenSSH server to bind to. This is also the default when trying to connect to a node, but if the node currently has OpenSSH running on a different port then run deploy with `--port` to override the `ssh.port` configuration value. +* `mosh.enabled` -- If set to `true`, then mosh will be installed on the server. The default is `false`. + +Macros +---------------------------------------- + +When using evaluated ruby in a JSON configuration file, there are several special macros that are available. These are evaluated in the context of a node (available as the variable `self`). + +The following methods are available to the evaluated ruby: + +`variable.variable` + + > Any variable defined or inherited by a particular node configuration is available by just referencing it using either hash notation or object field notation (e.g. `['domain']['public']` or `domain.public`). Circular references are not allowed, but otherwise it is OK to nest evaluated values in other evaluated values. If a value has not been defined, the hash notation will return nil but the field notation will raise an exception. Properties of services, tags, and the global provider can all be referenced the same way. For example, `global.services['openvpn'].x509.dh`. + +`nodes` + + > A hash of all nodes. This list can be filtered. + +`nodes_like_me` + + > A hash of nodes that have the same deployment tags as the current node (e.g. 'production' or 'local'). + +`global.services` + + > A hash of all services, e.g. `global.services['openvpn']` would return the "openvpn" service. + +`global.tags` + + > A hash of all tags, e.g. `global.tags['production']` would return the "production" tag. + + `global.provider` + + > Can be used to access variables defined in `provider.json`, e.g. `global.provider.contacts.default`. + +`file(filename)` + + > Inserts the full contents of the file. If the file is an erb template, it is rendered. The filename can either be one of the pre-defined file symbols, or it can be a path relative to the "files" directory in your provider instance. E.g, `file :ca_cert` or `files 'ca/ca.crt'`. + +`file_path(filename)` + + > Ensures that the file will get rsynced to the node as an individual file. The value returned by `file_path` is the full path where this file will ultimately live when deploy to the node. e.g. `file_path :ca_cert` or `file_path 'branding/images/logo.png'`. + +`secret(:symbol)` + + > Returns the value of a secret in secrets.json (or creates it if necessary).

The `leap` command handles SSH slightly differently for these nodes. + +Basically, all the SSH security is turned off for local nodes. Since local nodes only exist for a short time on your computer and can't be reached from the internet, this is not a problem. + +Specifically, for local nodes: + +1. `known_hosts` is never updated with local node keys, since the SSH public key of a local node is different for each user. +2. `leap` entirely skips the checking of host keys when connecting with a local node. +3. `leap` adds the public Vagrant SSH key to the list of SSH keys for a user. The public Vagrant SSH key is a shared and insecure key that has root access to most Vagrant virtual machines. + +When SSH host key changes +------------------------------- + +If the host key for a node has changed, you will get an error "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED". + +To fix this, you need to remove the file `files/nodes/stompy/stompy_ssh.pub` and run `leap node init stompy`, where the node's name is 'stompy'. **Only do this if you are ABSOLUTELY CERTAIN that the node's SSH host key has changed**. + +Changing the SSH port +-------------------------------- + +Suppose you have a node `blinky` that has SSH listening on port 22 and you want to make it port 2200. + +First, modify the configuration for `blinky` to specify the variable `ssh.port` as 2200. Usually, this is done in `common.json` or in a tag file. + +For example, you could put this in `tags/production.json`: + + { + "ssh": { + "port": 2200 + } + } + +Run `leap compile` and open `hiera/blinky.yaml` to confirm that `ssh.port` is set to 2200. The port number must be specified as a number, not a string (no quotes). + +Then, you need to deploy this change so that SSH will bind to 2200. You cannot simply run `leap deploy blinky` because this command will default to using the variable `ssh.port` which is now `2200` but SSH on the node is still bound to 22. + +So, you manually override the port in the deploy command, using the old port: + + leap deploy --port 22 blinky + +Afterwards, SSH on `blinky` should be listening on port 2200 and you can just run `leap deploy blinky` from then on. + +Sysadmins with multiple SSH keys +----------------------------------- + +The command `leap add-user --self` allows only one SSH key.

Do this: + + rm -r users/userx + leap deploy + +X.509 Certificates +================================ + +Configuration options +------------------------------------------- + +The `ca` option in provider.json provides settings used when generating CAs and certificates. The defaults are as follows: + + { + "ca": { + "name": "= global.provider.ca.organization + ' Root CA'", + "organization": "= global.provider.name[global.provider.default_language]", + "organizational_unit": "= 'https://' + global.provider.domain", + "bit_size": 4096, + "digest": "SHA256", + "life_span": "10y", + "server_certificates": { + "bit_size": 2048, + "digest": "SHA256", + "life_span": "1y" + }, + "client_certificates": { + "bit_size": 2048, + "digest": "SHA256", + "life_span": "2m", + "limited_prefix": "LIMITED", + "unlimited_prefix": "UNLIMITED" + } + } + } + +You should not need to override these defaults in your own provider.json, but you can if you want to. To see what values are used for your provider, run `leap inspect provider.json`. + +NOTE: A certificate `bit_size` greater than 2048 will probably not be recognized by most commercial CAs. + +Certificate Authorities +----------------------------------------- + +There are three x.509 certificate authorities (CA) associated with your provider: + +1. **Commercial CA:** It is strongly recommended that you purchase a commercial cert for your primary domain. The goal of platform is to not depend on the commercial CA system, but it does increase security and usability if you purchase a certificate. The cert for the commercial CA must live at `files/cert/commercial_ca.crt`. +2. **Server CA:** This is a self-signed CA responsible for signing all the **server** certificates. The private key lives at `files/ca/ca.key` and the public cert lives at `files/ca/ca.crt`. The key is very sensitive information and must be kept private. The public cert is distributed publicly. +3. **Client CA:** This is a self-signed CA responsible for signing all the **client** certificates. The private key lives at `files/ca/client_ca.key` and the public cert lives at `files/ca/client_ca.crt`. Neither file is distribute publicly. It is not a big deal if the private key for the client CA is compromised, you can just generate a new one and re-deploy. + +To generate both the Server CA and the Client CA, run the command: + + leap cert ca + +Server certificates +----------------------------------- + +Most every server in your service provider will have a x.509 certificate, generated by the `leap` command using the Server CA. Whenever you modify any settings of a node that might affect it's certificate (like changing the IP address, hostname, or settings in provider.json), you can magically regenerate all the certs that need to be regenerated with this command: + + leap cert update + +Run `leap help cert update` for notes on usage options. + +Because the server certificates are generated locally on your personal machine, the private key for the Server CA need never be put on any server. It is up to you to keep this file secure. + +Client certificates +-------------------------------- + +Every leap client gets its own time-limited client certificate. This cert is use to connect to the OpenVPN gateway (and probably other things in the future). It is generated on the fly by the webapp using the Client CA. + +To make this work, the private key of the Client CA is made available to the webapp. This might seem bad, but compromise of the Client CA simply allows the attacker to use the OpenVPN gateways without paying. In the future, we plan to add a command to automatically regenerate the Client CA periodically. + +There are two types of client certificates: limited and unlimited. A client using a limited cert will have its bandwidth limited to the rate specified by `provider.service.bandwidth_limit` (in Bytes per second). An unlimited cert is given to the user if they authenticate and the user's service level matches one configured in `provider.service.levels` without bandwidth limits. Otherwise, the user is given a limited client cert. + +Commercial certificates +----------------------------------- + +We strongly recommend that you use a commercial signed server certificate for your primary domain (in other words, a certificate with a common name matching whatever you have configured for `provider.domain`). This provides several benefits: + +1. When users visit your website, they don't get a scary notice that something is wrong. +2. When a user runs the LEAP client, selecting your service provider will not cause a warning message. +3. When other providers first discover your provider, they are more likely to trust your provider key if it is fetched over a commercially verified link. + +The LEAP platform is designed so that it assumes you are using a commercial cert for the primary domain of your provider, but all other servers are assumed to use non-commercial certs signed by the Server CA you create. + +To generate a CSR, run: + + leap cert csr + +This command will generate the CSR and private key matching `provider.domain` (you can change the domain with `--domain=DOMAIN` switch). It also generates a server certificate signed with the Server CA. You should delete this certificate and replace it with a real one once it is created by your commercial CA. + +The related commercial cert files are: + + files/ + certs/ + domain.org.crt # Server certificate for domain.org, obtained by commercial CA. + domain.org.csr # Certificate signing request + domain.org.key # Private key for you certificate + commercial_ca.crt # The CA cert obtained from the commercial CA. + +The private key file is extremely sensitive and care should be taken with its provenance. + +If your commercial CA has a chained CA cert, you should be OK if you just put the **last** cert in the chain into the `commercial_ca.crt` file. This only works if the other CAs in the chain have certs in the debian package `ca-certificates`, which is the case for almost all CAs. + +If you want to add additional fields to the CSR, like country, city, or locality, you can configure these values in provider.json like so: + + "ca": { + "server_certificates": { + "country": "US", + "state": "Washington", + "locality": "Seattle" + } + } + +If they are not present, the CSR will be created without them.

This location information is used for two things: + +* Determine which nodes can, or must, communicate with one another via a local network. The way some virtualization environments work, like OpenStack, requires that nodes communicate via the local network if they are on the same network. +* Allows the client to prefer connections to nodes that are closer in physical proximity to the user. This is particularly important for OpenVPN nodes. + +The location stanza in a node's config file looks like this: + + { + "location": { + "id": "ankara", + "name": "Ankara", + "country_code": "TR", + "timezone": "+2", + "hemisphere": "N" + } + } + +The fields: + +* `id`: An internal handle to use for this location. If two nodes have match `location.id`, then they are treated as being on a local network with one another. This value defaults to downcase and underscore of `location.name`. +* `name`: Can be anything, might be displayed to the user in the client if they choose to manually select a gateway. +* `country_code`: The [ISO 3166-1](https://en.wikipedia.org/wiki/ISO_3166-1) two letter country code. +* `timezone`: The timezone expressed as an offset from UTC (in standard time, not daylight savings). You can look up the timezone using this [handy map](http://www.timeanddate.com/time/map/). +* `hemisphere`: This should be "S" for all servers in South America, Africa, or Australia. Otherwise, this should be "N". + +These location options are very imprecise, but good enough for most usage. The client often does not know its own location precisely either. Instead, the client makes an educated guess at location based on the OS's timezone and locale. + +If you have multiple nodes in a single location, it is best to use a tag for the location.

Then, if you use environment pinning, the node will be ignored when you deploy. For example: + + { + "environment": "disabled" + } + +Then use `leap env pin ENV` to pin the environment to something other than 'disabled'. This only works if all the other nodes are also assigned to some environment. + +**Option 2: enabled == false** + +If a node has a property `enabled` set to false, then the `leap` command will skip over the node and pretend that it does not exist. For example: + + { + "ip_address": "1.1.1.1", + "services": ["openvpn"], + "enabled": false + } + +**Options 3: no-deploy** + +If the file `/etc/leap/no-deploy` exists on a node, then when you run the commmand `leap deploy` it will halt and prevent a deploy from going through (if the node was going to be included in the deploy). diff --git a/pages/docs/platform/service-diagram.odg b/pages/docs/platform/service-diagram.odg Binary files differnew file mode 100644 index 0000000..09265c2 --- /dev/null +++ b/pages/docs/platform/service-diagram.odg diff --git a/pages/docs/platform/service-diagram.png b/pages/docs/platform/service-diagram.png Binary files differnew file mode 100644 index 0000000..85e6243 --- /dev/null +++ b/pages/docs/platform/service-diagram.png diff --git a/pages/docs/platform/troubleshooting/en.haml b/pages/docs/platform/troubleshooting/en.haml new file mode 100644 index 0000000..f0f1359 --- /dev/null +++ b/pages/docs/platform/troubleshooting/en.haml @@ -0,0 +1,3 @@ +- @title = "Troubleshooting" + += child_summaries

This is important because the provider configurations you are creating contain sensitive data that should not reside on a remote machine.

If you receive an error when doing this, please read through the README.md in the `leap_cli` source to try and resolve any problems before going forwards. + +Check out the platform +-------------------------- + +The LEAP Platform is a series of puppet recipes and modules that will be used to configure your provider. You will need a local copy of the platform that will be used to setup your nodes and manage your services. To begin with, you will not need to modify the LEAP Platform. + +First we'll create a directory for LEAP things, and then we'll check out the platform code and initalize the modules: + + $ mkdir ~/leap + $ cd ~/leap + $ git clone --recursive https://leap.se/git/leap_platform.git + + +Provider Setup +============== + +A provider instance is a directory tree, usually stored in git, that contains everything you need to manage an infrastructure for a service provider. In this case, we create one for example.org and call the instance directory 'example'. + + $ mkdir -p ~/leap/example + +Bootstrap the provider +----------------------- + +Now, we will initialize this directory to make it a provider instance. Your provider instance will need to know where it can find the local copy of the git repository leap_platform, which we setup in the previous step. + + $ cd ~/leap/example + $ leap new . + +NOTES: + . make sure you include that trailing dot! + +The `leap new` command will ask you for several required values: + +* domain: The primary domain name of your service provider. In this tutorial, we will be using "example.org". +* name: The name of your service provider (we use "Example"). +* contact emails: A comma separated list of email addresses that should be used for important service provider contacts (for things like postmaster aliases, Tor contact emails, etc). +* platform: The directory where you have a copy of the `leap_platform` git repository checked out. + +You could also have passed these configuration options on the command-line, like so: + + $ leap new --contacts your@email.here --domain example.org --name Example --platform=~/leap/leap_platform . + +You may want to poke around and see what is in the files we just created. For example: + + $ cat provider.json + +Optionally, commit your provider directory using the version control software you fancy. For example: + + $ git init + $ git add . + $ git commit -m "initial provider commit" + +Now add yourself as a privileged sysadmin who will have access to deploy to servers: + + $ leap add-user --self + +NOTE: in most cases, `leap` must be run from within a provider instance directory tree (e.g. ~/leap/example). + +Create provider certificates +---------------------------- + +Create two certificate authorities, one for server certs and one for client +certs (note: you only need to run this one command to get both): + + $ leap cert ca + +Create a temporary cert for your main domain (you should replace with a real commercial cert at some point) + + $ leap cert csr + +To see details about the keys and certs that the prior two commands created, you can use `leap inspect` like so: + + $ leap inspect files/ca/ca.crt + +NOTE: the files `files/ca/*.key` are extremely sensitive and must be carefully protected. The other key files are much less sensitive and can simply be regenerated if needed. + + +Edit provider.json configuration +-------------------------------------- + +There are a few required settings in provider.json. At a minimum, you must have: + + { + "domain": "example.org", + "name": "Example", + "contacts": { + "default": "email1@example.org" + } + } + +For a full list of possible settings, you can use `leap inspect` to see how provider.json is evaluated after including the inherited defaults: + + $ leap inspect provider.json + + +Setup the provider's node and services +-------------------------------------- + +A "node" is a server that is part of your infrastructure. Every node can have one or more services associated with it. Some nodes are "local" and used only for testing, see [Development](development) for more information. + +Create a node, with all the services needed for Email - "couchdb", "mx", "soledad" and "webapp": + + $ leap node add node1 ip_address:x.x.x.w services:couchdb,mx,soledad,webapp tags:production + +NOTE: replace x.x.x.w with the actual IP address of this node + +This created a node configuration file in `nodes/node1.json`, but it did not do anything else. It also added the 'tag' called 'production' to this node. Tags allow us to conveniently group nodes together. When creating nodes, you should give them the tag 'production' if the node is to be used in your production infrastructure. + +Initialize the nodes +-------------------- + +Node initialization only needs to be done once, but there is no harm in doing it multiple times: + + $ leap node init production + +This will initialize the node with the tag "production". When `leap node init` is run, you will be prompted to verify the fingerprint of the SSH host key and to provide the root password of the server. You should only need to do this once. + + +Deploy the LEAP platform to the nodes +-------------------- + +Now you should deploy the platform recipes to the node. [Deployment can take a while to run](http://xkcd.com/303/), especially on the first run, as it needs to update the packages on the new machine. + + $ leap deploy + +Watch the output for any errors (in red), if everything worked fine, you should now have your first running node. If you do have errors, try doing the deploy again. + + +Setup DNS +--------- + +Now that you have the node configured, you should create the DNS entrie for this node. + +Set up your DNS with these hostnames: + + $ leap list --print ip_address,domain.full,dns.aliases + node1 x.x.x.w, node1.example.org, example.org, api.example.org, nicknym.example.org + +Alternately, you can adapt this zone file snippet: + + $ leap compile zone + +If you cannot edit your DNS zone file, you can still test your provider by adding this entry to your local resolver hosts file (`/etc/hosts` for linux): + + x.x.x.w node1.example.org example.org api.example.org nicknym.example.org + +Please don't forget about these entries, they will override DNS queries if you setup your DNS later. + + +What is going on here? +-------------------------------------------- + +First, some background terminology: + +* **puppet**: Puppet is a system for automating deployment and management of servers (called nodes). +* **hiera files**: In puppet, you can use something called a 'hiera file' to seed a node with a few configuration values. In LEAP, we go all out and put *every* configuration value needed for a node in the hiera file, and automatically compile a custom hiera file for each node. + +When you run `leap deploy`, a bunch of things happen, in this order: + +1. **Compile hiera files**: The hiera configuration file for each node is compiled in YAML format and saved in the directory `hiera`. The source material for this hiera file consists of all the JSON configuration files imported or inherited by the node's JSON config file. +* **Copy required files to node**: All the files needed for puppet to run are rsync'ed to each node. This includes the entire leap_platform directory, as well as the node's hiera file and other files needed by puppet to set up the node (keys, binary files, etc). +* **Puppet is run**: Once the node is ready, leap connects to the node via ssh and runs `puppet apply`. Puppet is applied locally on the node, without a daemon or puppetmaster. + +You can run `leap -v2 deploy` to see exactly what commands are being executed. + +<!-- See [under the hood](under-the-hood) for more details. --> + + +Test that things worked correctly +================================= + +You should now one machine with the LEAP platform email service deployed to it. + + +Access the web application +-------------------------------------------- + +In order to connect to the web application in your browser, you need to point your domain at the IP address of your new node. + +Next, you can connect to the web application either using a web browser or via the API using the LEAP client. To use a browser, connect to https://example.org (replacing that with your domain). Your browser will complain about an untrusted cert, but for now just bypass this. From there, you should be able to register a new user and login. + +Testing with leap_cli +--------------------- + +Use the test command to run a set of different tests: + + leap test + + +Additional information +====================== + +It is useful to know a few additional things. + +Useful commands +--------------- + +Here are a few useful commands you can run on your new local nodes: + +* `leap ssh web1` -- SSH into node web1 (requires `leap node init web1` first). +* `leap list` -- list all nodes. +* `leap list production` -- list only those nodes with the tag 'production' +* `leap list --print ip_address` -- list a particular attribute of all nodes. +* `leap cert update` -- generate new certificates if needed. + +See the full command reference for more information. + +Node filters +------------------------------------------- + +Many of the `leap` commands take a "node filter". You can use a node filter to target a command at one or more nodes. + +A node filter consists of one or more keywords, with an optional "+" before each keyword. + +* keywords can be a node name, a service type, or a tag. +* the "+" before the keyword constructs an AND condition +* otherwise, multiple keywords together construct an OR condition + +Examples: + +* `leap list openvpn` -- list all nodes with service openvpn. +* `leap list openvpn +production` -- only nodes of service type openvpn AND tag production. +* `leap deploy webapp openvpn` -- deploy to all webapp OR openvpn nodes. +* `leap node init vpn1` -- just init the node named vpn1. + +Keep track of your provider configurations +------------------------------------------ + +You should commit your provider changes to your favorite VCS whenever things change. This way you can share your configurations with other admins, all they have to do is to pull the changes to stay up to date.

This Quick Start guide will guide you through building a three node OpenVPN provider. + +Our goal +------------------ + +We are going to create a minimal LEAP provider offering OpenVPN service. This basic setup can be expanded by adding more OpenVPN nodes to increase capacity, or more webapp and couchdb nodes to increase availability (performance wise, a single couchdb and a single webapp are more than enough for most usage, since they are only lightly used, but you might want redundancy). Please note: currently it is not possible to safely add additional couchdb nodes at a later point. They should all be added in the beginning, so please consider carefully if you would like more before proceeding. + +Our goal is something like this: + + $ leap list + NODES SERVICES TAGS + cheetah couchdb production + wildebeest webapp production + ostrich openvpn production + +NOTE: You won't be able to run that `leap list` command yet, not until we actually create the node configurations. + +Requirements +------------ + +In order to complete this Quick Start, you will need a few things: + +* You will need three real or paravirtualized virtual machines (KVM, Xen, Openstack, Amazon, but not Vagrant - sorry) that have a basic Debian Stable installed. If you allocate 20G of disk space to each node for the system, after this process is completed, you will have used less than 10% of that disk space. If you allocate 2 CPUs and 8G of memory to each node, that should be more than enough to begin with. +* You should be able to SSH into them remotely, and know their root password, IP addresses and their SSH host keys +* You will need four different IPs. Each node gets a primary IP, and the OpenVPN gateway additionally needs a gateway IP. +* The ability to create/modify DNS entries for your domain is preferable, but not needed. If you don't have access to DNS, you can workaround this by modifying your local resolver, i.e. editing `/etc/hosts`. +* You need to be aware that this process will make changes to your systems, so please be sure that these machines are a basic install with nothing configured or running for other purposes +* Your machines will need to be connected to the internet, and not behind a restrictive firewall. +* You should work locally on your laptop/workstation (one that you trust and that is ideally full-disk encrypted) while going through this guide. This is important because the provider configurations you are creating contain sensitive data that should not reside on a remote machine. The `leap` command will login to your servers and configure the services. +* You should do everything described below as an unprivileged user, and only run those commands as root that are noted with *sudo* in front of them. Other than those commands, there is no need for privileged access to your machine, and in fact things may not work correctly. + +All the commands in this tutorial are run on your sysadmin machine. In order to complete the tutorial, the sysadmin will do the following: + +* Install pre-requisites +* Install the LEAP command-line utility +* Check out the LEAP platform +* Create a provider and its certificates +* Setup the provider's nodes and the services that will reside on those nodes +* Initialize the nodes +* Deploy the LEAP platform to the nodes +* Test that things worked correctly +* Some additional commands + +We will walk you through each of these steps. + + +Prepare your environment +======================== + +There are a few things you need to setup before you can get going. Just some packages, the LEAP cli and the platform. + +Install pre-requisites +-------------------------------- + +*Debian & Ubuntu* + +Install core prerequisites: + + $ sudo apt-get install git ruby ruby-dev rsync openssh-client openssl rake make bzip2 + +<!-- +*Mac OS* + +1. Install rubygems from https://rubygems.org/pages/download (unless the `gem` command is already installed). +--> + +NOTE: leap_cli requires ruby 1.9 or later. + + +Install the LEAP command-line utility +------------------------------------------------- + +Install the `leap` command from rubygems.org: + + $ sudo gem install leap_cli + +Alternately, you can install `leap` from source: + + $ git clone https://leap.se/git/leap_cli + $ cd leap_cli + $ rake build + $ sudo rake install + +You can also install from source as an unprivileged user, if you want. For example, instead of `sudo rake install` you can do something like this: + + $ rake install + # watch out for the directory leap is installed to, then i.e. + $ sudo ln -s ~/.gem/ruby/1.9.1/bin/leap /usr/local/bin/leap + +With either `rake install` or `sudo rake install`, you can use now /usr/local/bin/leap, which in most cases will be in your $PATH. + +If you have successfully installed the `leap` command, then you should be able to do the following: + + $ leap --help + +This will list the command-line help options. If you receive an error when doing this, please read through the README.md in the `leap_cli` source to try and resolve any problems before going forwards. + +Check out the platform +-------------------------- + +The LEAP Platform is a series of puppet recipes and modules that will be used to configure your provider. You will need a local copy of the platform that will be used to setup your nodes and manage your services. To begin with, you will not need to modify the LEAP Platform. + +First we'll create a directory for LEAP things, and then we'll check out the platform code and initalize the modules: + + $ mkdir ~/leap + $ cd ~/leap + $ git clone https://leap.se/git/leap_platform.git + $ cd leap_platform + $ git submodule sync; git submodule update --init + + +Provider Setup +============== + +A provider instance is a directory tree, usually stored in git, that contains everything you need to manage an infrastructure for a service provider. In this case, we create one for example.org and call the instance directory 'example'. + + $ mkdir -p ~/leap/example + +Bootstrap the provider +----------------------- + +Now, we will initialize this directory to make it a provider instance. Your provider instance will need to know where it can find the local copy of the git repository leap_platform, which we setup in the previous step. + + $ cd ~/leap/example + $ leap new . + +NOTES: + . make sure you include that trailing dot! + +The `leap new` command will ask you for several required values: + +* domain: The primary domain name of your service provider. In this tutorial, we will be using "example.org". +* name: The name of your service provider (we use "Example"). +* contact emails: A comma separated list of email addresses that should be used for important service provider contacts (for things like postmaster aliases, Tor contact emails, etc). +* platform: The directory where you have a copy of the `leap_platform` git repository checked out. + +You could also have passed these configuration options on the command-line, like so: + + $ leap new --contacts your@email.here --domain leap.example.org --name Example --platform=~/leap/leap_platform . + +You may want to poke around and see what is in the files we just created. For example: + + $ cat provider.json + +Optionally, commit your provider directory using the version control software you fancy. For example: + + $ git init + $ git add . + $ git commit -m "initial provider commit" + +Now add yourself as a privileged sysadmin who will have access to deploy to servers: + + $ leap add-user --self + +NOTE: in most cases, `leap` must be run from within a provider instance directory tree (e.g. ~/leap/example). + +Create provider certificates +---------------------------- + +Create two certificate authorities, one for server certs and one for client +certs (note: you only need to run this one command to get both): + + $ leap cert ca + +Create a temporary cert for your main domain (you should replace with a real commercial cert at some point) + + $ leap cert csr + +To see details about the keys and certs that the prior two commands created, you can use `leap inspect` like so: + + $ leap inspect files/ca/ca.crt + +Create the Diffie-Hellman parameters file, needed for forward secret OpenVPN ciphers: + + $ leap cert dh + +NOTE: the files `files/ca/*.key` are extremely sensitive and must be carefully protected. The other key files are much less sensitive and can simply be regenerated if needed. + + +Edit provider.json configuration +-------------------------------------- + +There are a few required settings in provider.json. At a minimum, you must have: + + { + "domain": "example.org", + "name": "Example", + "contacts": { + "default": "email1@example.org" + } + } + +For a full list of possible settings, you can use `leap inspect` to see how provider.json is evaluated after including the inherited defaults: + + $ leap inspect provider.json + + +Setup the provider's nodes and services +--------------------------------------- + +A "node" is a server that is part of your infrastructure. Every node can have one or more services associated with it. Some nodes are "local" and used only for testing, see [Development](development) for more information. + +Create a node, with the service "webapp": + + $ leap node add wildebeest ip_address:x.x.x.w services:webapp tags:production + +NOTE: replace x.x.x.w with the actual IP address of this node + +This created a node configuration file in `nodes/wildebeest.json`, but it did not do anything else. It also added the 'tag' called 'production' to this node. Tags allow us to conveniently group nodes together. When creating nodes, you should give them the tag 'production' if the node is to be used in your production infrastructure. + +The web application and the VPN nodes require a database, so lets create the database server node: + + $ leap node add cheetah ip_address:x.x.x.x services:couchdb tags:production + +NOTE: replace x.x.x.x with the actual IP address of this node + +Now we need the OpenVPN gateway, so lets create that node: + + $ leap node add ostrich ip_address:x.x.x.y openvpn.gateway_address:x.x.x.z services:openvpn tags:production + +NOTE: replace x.x.x.y with the IP address of the machine, and x.x.x.z with the second IP. openvpn gateways must be assigned two IP addresses, one for the host itself and one for the openvpn gateway. We do this to prevent incoming and outgoing VPN traffic on the same IP. Without this, the client might send some traffic to other VPN users in the clear, bypassing the VPN. + + +Setup DNS +--------- + +Now that you have the nodes configured, you should create the DNS entries for these nodes. + +Set up your DNS with these hostnames: + + $ leap list --print ip_address,domain.full,dns.aliases + cheetah x.x.x.w, cheetah.example.org, null + wildebeest x.x.x.x, wildebeest.example.org, api.example.org + ostrich x.x.x.y, ostrich.example.org, null + +Alternately, you can adapt this zone file snippet: + + $ leap compile zone + +If you cannot edit your DNS zone file, you can still test your provider by adding entries to your local resolver hosts file (`/etc/hosts` for linux): + + x.x.x.w cheetah.example.org + x.x.x.x wildebeest.example.org api.example.org example.org + x.x.x.y ostrich.example.org + +Please don't forget about these entries, they will override DNS queries if you setup your DNS later. + + +Initialize the nodes +-------------------- + +Node initialization only needs to be done once, but there is no harm in doing it multiple times: + + $ leap node init production + +This will initialize all nodes with the tag "production". When `leap node init` is run, you will be prompted to verify the fingerprint of the SSH host key and to provide the root password of the server(s). You should only need to do this once. + +If you prefer, you can initalize each node, one at a time: + + $ leap node init wildebeest + $ leap node init cheetah + $ leap node init ostrich + +Deploy the LEAP platform to the nodes +-------------------- + +Now you should deploy the platform recipes to the nodes. [Deployment can take a while to run](http://xkcd.com/303/), especially on the first run, as it needs to update the packages on the new machine. + +*Important notes:* currently nodes must be deployed in a certain order. The underlying couch database node(s) must be deployed first, and then all other nodes. Also you need to configure and deploy all of the couchdb nodes that you plan to use at this time, as currently you cannot add more of them later later ([See](https://leap.se/es/docs/platform/known-issues#CouchDB.Sync)). + + $ leap deploy cheetah + +Watch the output for any errors (in red), if everything worked fine, you should now have your first running node. If you do have errors, try doing the deploy again. + +However, to deploy our three-node openvpn setup, we need the database and LEAP web application requires a database to run, so let's deploy to the couchdb and openvpn nodes: + + $ leap deploy wildebeest + $ leap deploy ostrich + + +What is going on here? +-------------------------------------------- + +First, some background terminology: + +* **puppet**: Puppet is a system for automating deployment and management of servers (called nodes). +* **hiera files**: In puppet, you can use something called a 'hiera file' to seed a node with a few configuration values. In LEAP, we go all out and put *every* configuration value needed for a node in the hiera file, and automatically compile a custom hiera file for each node. + +When you run `leap deploy`, a bunch of things happen, in this order: + +1. **Compile hiera files**: The hiera configuration file for each node is compiled in YAML format and saved in the directory `hiera`. The source material for this hiera file consists of all the JSON configuration files imported or inherited by the node's JSON config file. +* **Copy required files to node**: All the files needed for puppet to run are rsync'ed to each node. This includes the entire leap_platform directory, as well as the node's hiera file and other files needed by puppet to set up the node (keys, binary files, etc). +* **Puppet is run**: Once the node is ready, leap connects to the node via ssh and runs `puppet apply`. Puppet is applied locally on the node, without a daemon or puppetmaster. + +You can run `leap -v2 deploy` to see exactly what commands are being executed. + + +Test that things worked correctly +================================= + +You should now have three machines with the LEAP platform deployed to them, one for the web application, one for the database and one for the OpenVPN gateway. + +To run troubleshooting tests: + + leap test + +If you want to confirm for yourself that things are working, you can perform the following manual tests. + +### Access the web application + +In order to connect to the web application in your browser, you need to point your domain at the IP address of the web application node (named wildebeest in this example). + +There are a lot of different ways to do this, but one easy way is to modify your `/etc/hosts` file. First, find the IP address of the webapp node: + + $ leap list webapp --print ip_address + +Then modify `/etc/hosts` like so: + + x.x.x.w leap.example.org + +Replacing 'leap.example.org' with whatever you specified as the `domain` in the `leap new` command. + +Next, you can connect to the web application either using a web browser or via the API using the LEAP client. To use a browser, connect to https://leap.example.org (replacing that with your domain). Your browser will complain about an untrusted cert, but for now just bypass this. From there, you should be able to register a new user and login. + +### Use the VPN + +You should be able to simply test that the OpenVPN gateway works properly by doing the following: + + $ leap test init + $ sudo openvpn test/openvpn/production_unlimited.ovpn + +Or, you can use the LEAP client (called "bitmask") to connect to your new provider, create a user and then connect to the VPN. + + +Additional information +====================== + +It is useful to know a few additional things. + +Useful commands +--------------- + +Here are a few useful commands you can run on your new local nodes: + +* `leap ssh wildebeest` -- SSH into node wildebeest (requires `leap node init wildebeest` first). +* `leap list` -- list all nodes. +* `leap list production` -- list only those nodes with the tag 'production' +* `leap list --print ip_address` -- list a particular attribute of all nodes. +* `leap cert update` -- generate new certificates if needed. + +See the full command reference for more information. + +Node filters +------------------------------------------- + +Many of the `leap` commands take a "node filter". You can use a node filter to target a command at one or more nodes. + +A node filter consists of one or more keywords, with an optional "+" before each keyword. + +* keywords can be a node name, a service type, or a tag. +* the "+" before the keyword constructs an AND condition +* otherwise, multiple keywords together construct an OR condition + +Examples: + +* `leap list openvpn` -- list all nodes with service openvpn. +* `leap list openvpn +production` -- only nodes of service type openvpn AND tag production. +* `leap deploy webapp openvpn` -- deploy to all webapp OR openvpn nodes. +* `leap node init ostrich` -- just init the node named ostrich. + +Keep track of your provider configurations +------------------------------------------ + +You should commit your provider changes to your favorite VCS whenever things change. This way you can share your configurations with other admins, all they have to do is to pull the changes to stay up to date. Every time you make a change to your provider, such as adding nodes, services, generating certificates, etc. you should add those to your VCS, commit them and push them to where your repository is hosted. + +Note that your provider directory contains secrets! Those secrets include passwords for various services. You do not want to have those passwords readable by the world, so make sure that wherever you are hosting your repository, it is not public for the world to read. + +What's next +----------------------------------- + +Read the [LEAP platform guide](guide) to learn about planning and securing your infrastructure. + diff --git a/pages/docs/tech/en.haml b/pages/docs/tech/en.haml new file mode 100644 index 0000000..c03b89b --- /dev/null +++ b/pages/docs/tech/en.haml @@ -0,0 +1,5 @@ +- @title = "LEAP Technology Notes" +- @nav_title = "Technology" +- @summary = "Musings, notes, and background information on various technology issues that relate to LEAP." + += child_summaries

But if you do care about usability and features, then you are stuck with finding solutions to these problems. + +## Our solutions + +In our work, LEAP has tried to directly face down these seven problems. In some cases, we have come up with solid solutions. In other cases, we are moving forward with temporary stop-gap measures and investigating long term solutions. In two cases, we have no current plan for addressing the problems. + +### Public key problem + +The problem: + +> Public keys is very difficult for users to manage, but without it you cannot have confidentiality. + +If proper key management is a precondition for secure communication, but it is too difficult for most users, what hope do we have? + +The problem of public keys breaks down into five discrete issues: + +* **Key discovery** is the process of obtaining the public key for a particular user identifier. Currently, there is no commonly accepted standard for mapping an identifier to a public key. For OpenPGP, many people use keyservers for this (although the keyserver infrastructure was not designed to be used in this way). A related problem is how a client can discover public key information for all the contacts in their addressbook for phonebook without revealing this information to a third party. +* **Key validation** is the process ensuring that a public key really does map to a particular user identifier. This is also called the "binding problem" in computer science. Traditional methods of key validation have recently become discredited. +* **Key availability** is the assurance that the user will have access, whenever needed, to their keys and the keys of other users. Almost every attempt to solve the key validation problem turns into a key availability problem, because once you have validated a public key, you need to make sure that this validation is available to the user on all the possible devices they might want to send or receive messages on. +* **Key revocation** is the process of ensuring that people do not use an old public key that has been superseded by a new one. + +Of these problems, key validation is the most difficult and most central to proper key management. The two traditional methods of key validation are either the X.509 Certificate Authority (CA) system or the decentralized "Web of Trust" (WoT). Recently, these schemes have come under intense criticism. Repeated security lapses at many of the Certificate Authorities have revealed serious flaws in the CA system. On the other hand, in an age where we better understand the power of social network analysis and the sensitivity of the social graph, the exposure of metadata by a "Web of Trust" is no longer acceptable from a security standpoint. + +An alternative method of key validation is called TOFU for Trust On First Use. With TOFU, a public key is assumed to be the right key the first time it is used. TOFU can work well for long term associations and for people who are not being targeted for attack, but its security relies on the security of the discovery transport and the application's ability to retain a memory of discovered keys. + +TOFU can break down in many real-world situations where a user might need to generate new keys or securely communicate with a new contact. TOFU is widely used for protocols like SSH, where the user receives confirmation of key continuity each time they connect to a server. There is no such confirmation with asynchronous messaging protocols, making TOFU much less appropriate in these situations. + +Other strategies for addressing parts of the key management problem include: + +1. Inline Keys: Many projects plan to facilitate discovery by simply including the user's public key in every outgoing message (as an attachment, in a footer, or in a header). +1. DNS: Key distributed via DNSSEC, where a service provider adds a DNS entry for each user containing the user's public key or fingerprint. This places all the trust in the DNS owner. +1. Network perspective: Validation by key endorsement (third party signatures), with audits performed via network perspective. +1. Introductions: Discovery and validation of keys through acquaintance introduction. +1. Mobile: Although too lengthy to manually transcribe, an app on a mobile device can be used to easily exchange keys in person (for example, via a QR code or bluetooth connection). +1. Append-only log: There is a proposal to modify Certificate Transparency to handle user accounts, where audits are performed against append-only logs. +1. Biometric feedback: In the one case of voice communication, you can use recognition of the other person's voice as a means to validate the key (when used in combination with a Short Authentication String). This is how ZRTP works. + +For LEAP, we have developed a unique federated system called [Nicknym](/nicknym) that automatically discovers and validates public keys allowing the user to take advantage of public key cryptography without knowing anything about keys or signatures. Nicknym uses a combination of TOFU, provider endorsement, and network perspective. There is also a new proposal very similar to Nicknym called [Nyms](https://nymsio.github.io/) which we hope to also support. Nyms adds the ability of users from non-participating service providers to register their keys. + +### Availability problem + +The problem: + +> People want to smoothly switch devices, and restore their data if they lose a device, but this very difficult to do securely. + +Users today demand the ability to access their data on multiple devices and to have piece of mind that their data will not be lost forever if they lose a device. + +At LEAP, we have worked to solve the availability problem with a system we call [Soledad](/soledad) (for Synchronization of Locally Encrypted Documents Among Devices). Soledad gives the client application an encrypted, synchronized, searchable document database. All data is client encrypted, both when it is stored on the local device and synced with the cloud. This is very powerful, as it allow the client developer to take advantage of a rich document database without needing to worry about how it is backed up or synchronized. + +As far as we know, there is nothing else like it, either in the free software or commercial world. However, there are several projects in a similar problem space: + +* [Mylar](http://css.csail.mit.edu/mylar/), for client-encrypting web application data. +* [Crypton](https://crypton.io/), for client-encrypting web application data. +* [Firefox Sync](https://wiki.mozilla.org/Services/Sync) + +Soledad tries to solve the problem of general data availability, but other initiatives have tried to tackle the more narrow problem of availability of private keys and discovered public keys. These initiatives include: + +* [Whiteout key sync](https://blog.whiteout.io/2014/07/07/secure-pgp-key-sync-a-proposal/) +* Nilcat, experimental [code for cloud storage of keys](https://github.com/mettle/nilcat) +* Ben Laurie's [proposed protocol for storing secrets in the cloud](http://www.links.org/files/nigori/nigori-protocol-01.html) +* Phillip Hallam-Baker's [thoughts along similar lines](http://tools.ietf.org/html/draft-hallambaker-prismproof-key-00) + +### Update problem + +The problem: + +> Almost universally, software updates are done in ways that invite attacks and device compromises. + +The sad state of update security is especially troublesome because update attacks can now be purchased off the shelf by repressive regimes. The problem of software update is particular bad on desktop platforms. In the case of mobile and HTML5 apps, the vulnerabilities are not as dire, but the issues are also harder to fix. + +To address the update problem, LEAP is adopting a unique update system called Thandy from the Tor project. Thandy is complex to manage, but is very effective at preventing known update attacks. + +Thandy, and the related [TUF](https://updateframework.com), are designed to address the many [security vulnerabilities in existing software update systems](https://github.com/theupdateframework/tuf/blob/develop/SECURITY.md). In one example, other update systems suffer from an inability of the client to confirm that they have the most up-to-date copy, thus opening a huge vulnerability where the attacker simply waits for a security upgrade, prevents the upgrade, and launches an attack exploiting the vulnerability that should have just been fixed. Thandy/TUF provides a unique mechanism for distributing and verifying updates so that no client device will install the wrong update or miss an update without knowing it. + +Related to the update problem is the backdoor problem: how do you know that an update does not have a backdoor added by the software developers themselves? Probably the best approach is that taken by [Gitian](https://gitian.org/), which provides a "deterministic build process to allow multiple builders to create identical binaries". We hope to adopt Gitian in the future. + +### Meta-data problem + +The problem: + +> Existing protocols are vulnerable to meta-data analysis, even though meta-data is often much more sensitive than content. + +As a short term measure, we are integrating opportunistic encrypted transport (TLS) for email and chat messages when relayed among servers. There are two important aspects to this: + +* Relaying servers need a solid way to discover and validate the keys of one another. For this, we are initially using DNSSEC/DANE. +* An attacker must not be able to downgrade the encrypted transport back to cleartext. For this, we are modifying software to ensure that encrypted transport cannot later be downgraded. + +This approach is potentially effective against external network observers, but does not protect the meta-data from the service providers themselves. Also, it does not, by itself, protect against more advanced attacks involving timing and traffic analysis. + +In the medium term, LEAP plans to support direct delivery from client to server via Tor for service providers that support this. These anonymously delivered messages would be kept in a separate folder and only displayed to the user if the message signatures are valid. There is a lot of open debate as to the efficacy of using a low-latency onion routing network like Tor for something that might be better suited to a high latency mixing network. For now, Tor is useful because it exists and has a lot of traffic already. For a great discussion comparing mix networks and onion routing, see [Tom Ritter's blog post on the topic](https://ritter.vg/blog-mix_and_onion_networks.html). + +In the long term, we plan to adopt one of the proposed schemes for securely routing meta-data. These include: + +* Auto-alias-pairs: Each party auto-negotiates aliases for communicating with each other. Behind the scenes, the client then invisibly uses these aliases for subsequent communication. The advantage is that this is backward compatible with existing routing. The disadvantage is that the user's server stores a list of their aliases. As an improvement, you could add the possibility of a third party service to maintain the alias map. +* Onion-routing-headers: A message from user A to user B is encoded so that the "to" routing information only contains the name of B's server. When B's server receives the message, it unwraps (unencrypts) a supplementary header that contains the actual user "B". Like aliases, this provides no benefit if both users are on the same server. As an improvement, the message could be routed through intermediary servers. +* Third-party-dropbox: To exchange messages, user A and user B negotiate a unique "dropbox" URL for depositing messages, potentially using a third party. To send a message, user A would post the message to the "dropbox". To receive a message, user B would regularly polls this URL to see if there are new messages. +* Mixmaster-with-signatures: Messages are bounced through a mixmaster-like set of anonymization relays and then finally delivered to the recipient's server. The user's client only displays the message if it is encrypted, has a valid signature, and the user has previously added the sender to a 'allow list' (perhaps automatically generated from the list of validated public keys). +* Tor: One scheme employed by Pond is to simply allow for direct delivery over Tor from the sender's device to the recipient's server. This is fairly simple, and places all the work on the existing Tor network. + +In all of these cases, meta-data protected routing can make abuse prevention more difficult. For this reason, it probably makes sense to only allow once of these options once both parties have already exchanged key material, in order to prevent the user being flooded with anonymous Spam. + +### Asynchronous problem + +The problem: + +> For encrypted communication, you must currently choose between forward secrecy or the ability to communicate asynchronously. + +With the pace of growth in digital storage and decryption, forward secrecy is increasingly important. Otherwise, any encrypted communication you engage in today is likely to become cleartext communication in the near future. + +In the example of email and chat, we have OpenPGP with email and OTR with chat: the former provides asynchronous capabilities, and the latter forward secrecy, but neither one supports both abilities. We need both better security for email and the ability to send/receive offline chat messages. + +In the short term, we are layering forward secret transport for email and chat relay on top of traditional object encryption (OpenPGP). This approach is identical to our stop-gap approach for the meta-data problem, with the one addition that relaying servers need the ability to not simply negotiate TLS transport, but to also negotiate forward secret ciphers and to prevent a cipher downgrade. + +This approach is potentially effective against external network observers, but does not achieve forward secrecy from the service providers themselves. + +In the long term, we plan to work with other groups to create new encryption protocol standards that can be both asynchronous and forward secret: + +* [Triple elliptical curve Diffie-Hellman handshake](https://whispersystems.org/blog/simplifying-otr-deniability/) +* [Forward Secrecy Extensions for OpenPGP](http://tools.ietf.org/html/draft-brown-pgp-pfs-03) + +The [Axolotl protocol](https://github.com/trevp/axolotl/wiki) used by both Pond and TextSecure currently has the most mature approach to asynchronous forward secrecy. This could be added as an invisible upgrade to normal email encryption when the client detects that both parties support it. + +### Group problem + +The problem: + +> In practice, people work in groups, but public key cryptography doesn't. + +We have a lot of ideas, but we don't have any solutions yet to fix this. Essentially, the question is how to use existing public key primitives to create strong cryptographic groups, where membership and permissions are based on keys and not arbitrary server-maintained access control lists. + +Most of the interesting work in this area has been done by companies working on secure file backup/sync/sharing, such as Wuala and Spideroak. Unfortunately, there are not yet any good open protocols or free software packages that can handle group cryptography. + +At the moment, probably the best approach is the simple approach: a protocol where the client encrypts each message to each recipient individually, and has some mechanism to verify the transcript to ensure that all parties received the same messages. + +There is some free software work on some of interesting building blocks that could be useful in building group cryptography. For example: + +* [Proxy re-encryption](https://en.wikipedia.org/wiki/Proxy_re-encryption): This allows the server to re-encrypt to new recipients without gaining access to the cleartext. The [SELS mailing list manager](http://sels.ncsa.illinois.edu/) uses OpenPGP to implement a [clever scheme for proxy re-encryption](http://spar.isi.jhu.edu/~mgreen/proxy.pdf). +* [Ring signatures](https://en.wikipedia.org/wiki/Ring_signature): This allows any member of a group to sign, withing anyone knowing which member. + +### Resource problem + +The problem: + +> There are no open protocols to allow users to securely share a resource. + +For example, when using secure chat or secure federated social networking, you need some way to link to external media, such as an image, video or file, that has the same security guarantees as the message itself. Embedding this type of resource in the messages themselves is prohibitively inefficient. + +We don't have a proposal for how to address this problem. There are a lot of great initiatives working under the banner of read-write-web, but these do not take encryption into account. In many ways, solutions to the resource problem are dependent on solutions to the the group problem. + +As with the group problem, most of the progress in this area has been by people working on encrypted file sync (e.g. strategies like Lazy Revocation and Key Regression). + diff --git a/pages/docs/tech/hard-problems/pt.md b/pages/docs/tech/hard-problems/pt.md new file mode 100644 index 0000000..50c0541 --- /dev/null +++ b/pages/docs/tech/hard-problems/pt.md @@ -0,0 +1,133 @@ +@title = 'Problemas difíceis na comunicação segura' +@nav_title = 'Problemas difíceis' +@summary = "Como o LEAP aborda os problemas difíceis na comunicação segura" + +## Os sete grandes + +Se você pesquisar iniciativas interessantes para a criação de formas mais seguras de comunicação, verá que surge um padrão: aparentemente toda tentativa séria de construir um sistema para transmissão de mensagens seguras eventualmente se depara com a seguinte lista de sete problemas difíceis: + +1. **Problema da autenticidade**: a validação de chaves públicas é muito difícil para ser gerenciada por usuários, mas sem isso não é possível obter confidencialidade. +2. **Problema dos metadados**: os protocolos existentes são vulneráveis à análise de metadados, mesmo que os metadados muitas vezes sejam mais sensíveis do que o conteúdo da comunicação. +3. **Problema da assincronicidade**: para estabelecer comunicação criptografada, atualmente é necessário escolher entre sigilo futuro (forward secrecy) e a habilidade de se comunicar de forma assíncrona. +4. **Problema do grupo**: na prática, pessoas trabalham em grupos, mas a criptografia de chave pública não. +5. **Problema dos recursos**: não existem protocolos abertos que permitam aos usuários compartilharem um recurso de forma segura. +6. **Problema da disponibilidade**: as pessoas querem alternar suavemente entre dispositivos e restaurar seus dados se perderem um dispositivo, mas isso é bem difícil de se fazer com segurança. +7. **Problema da atualização**: quase que universalmente, atualizações de software são feitas de maneiras que são convidativas a ataques e comprometimento de dispositivos. + +Tais problemas parecem estar presentes independentemente da abordagem arquitetônica escolhida (autoridade centralizada, peer-to-peer distribuído ou servidores federados). + +É possível ignorar muitos desses problemas se você não se importar especificamente com a usabilidade ou com o conjunto de funcionalidades com as quais os/as usuários/as se acostumaram nos métodos contemporâneos de comunicação online. Mas se você se importa com a usabilidade e recursos, então você terá que encontrar soluções para esses problemas. + +## Nossas soluções + +Em nosso trabalho, o LEAP tentou enfrentar diretamente esses sete problemas. Em alguns casos, chegamos a soluções sólidas. Noutros, estamos avançando com medidas paliativas temporárias e investigando soluções de longo prazo. Em dois casos não temos nenhum plano atual para lidar com os problemas. + +### O problema da autenticidade + +O problema: + +> A validação de chaves públicas é muito difícil para ser gerenciada por usuários, mas sem isso não é possível obter confidencialidade. + +Se a validação de chaves adequada é um pressuposto para uma comunicação segura, mas é muito difícil para a maioria dos usuários/as, que esperança temos? Desenvolvemos um sistema federado único chamado [Nicknym](/nicknym) que descobre e valida automaticamente as chaves públicas, permitindo ao usuário tirar partido de criptografia de chave pública sem saber nada sobre chaves ou assinaturas. + +O protocolo padrão que existe hoje para solucionar este problema chama-se [DANE](https://en.wikipedia.org/wiki/DNS-based_Authentication_of_Named_Entities). O DANE pode ser a melhor opção no longo prazo, mas atualmente é difícil de ser configurado, difícil de ser utilizado por clientes, vaza informações sobre associação para um observador da rede, e depende da confiança na zona raíz do DNS e nas zonas TLD. + +### Problema dos metadados + +O problema: + +> Os protocolos existentes são vulneráveis à análise de metadados, mesmo que os metadados muitas vezes sejam mais sensíveis do que o conteúdo da comunicação. + +Como medida de curto prazo, estamos integrando transporte criptografado oportunístico (TLS) para email e mensagens de chat ao serem retransmitidas entre servidores. Há dois aspectos importantes nisso: + +* Servidores repetidores (relaying servers) precisam de uma maneira sólida para descobrir e validar as chaves uns dos outros. Para isso, estamos utilizando inicialmente DNSSEC/DANE. +* Um atacante não deve ser capaz de fazer o downgrade do transporte criptografado para texto não cifrado. Para isso, estamos modificando o software para assegurar que o transporte criptografado não possa sofrer downgrade. + +Tal abordagem é potencialmente eficaz contra observadores externos na rede, mas não protege os metadados dos próprios provedores de serviços. Além disso, ela não protege, por si só, contra ataques mais avançados que envolvam análise de tráfego e de tempo. + +No longo prazo, pretendemos adotar um dos vários esquemas distintos para roteamento seguro de metadados. Estes incluem: + +* Pareamento automático de pseudônimos (auto-alias-pairs): cada uma das partes autonegocia pseudônimos para se comunicarem umas com as outras. Nos bastidores, o cliente utiliza de forma invisível esses pseudônimos para a comunicação subsequente. A vantagem é que isso é compatível com o roteamento existente. A desvantagem é que o servidor do usuário/a armazena uma lista de seus pseudônimos. Como uma melhoria, pode-se adicionar a possibilidade de usar um serviço de terceiros para manter o mapa dos pseudônimos. +* Cabeçalhos de roteamento do tipo "cebola" (onion-routing-headers): uma mensagem de um/a usuário/a para o/a usuário/a B é codificada de forma que as informações de roteamento do destinatário/a contenham apenas o nome do servidor usado por B. Quando o servidor de B recebe a mensagem, decodifica um cabeçalho adicional que contém o utilizador real "B". Como o uso de pseudônimos, isso não proporciona benefícios se os usuários estão no mesmo servidor. Como uma melhoria, a mensagem pode ser encaminhada por meio de servidores intermediários. +* Caixa de depósito de terceiros (third-party dropbox): para trocar mensagens, o/a usuário/a A e o/a usuário/a B negociam uma URL única de uma "caixa de depósito" (dropbox) para depositar mensagens, potencialmente usando um agente intermediário. Para enviar uma mensagem, o usuário A depositaria a mensagem na caixa. Para receber uma mensagem, o usuário B acessaria regularmente esta URL para ver se há novas mensagens. +* Misturador com assinaturas (mixmaster-with-signatures): as mensagens são enviadas através de um conjunto de repetirores anonimizadores do tipo mixmaster e ao final são entregues ao servidor do destinatário. O programa cliente do usuário apenas exibe a mensagem se ela for criptografada, tiver uma assinatura válida, e se o usuário tiver adicionado anteriormente o remetente a uma 'lista de permissões' (talvez gerada automaticamente a partir da lista de chaves públicas validadas). + +Para uma boa discussão comparando redes misturadoras com roteamento cebola, veja a [postagem no blog de Tom Ritter](https://ritter.vg/blog-mix_and_onion_networks.html) sobre o tema. + +### Problema da assincronicidade + +O problema: + +> Para estabelecer comunicação criptografada, atualmente é necessário escolher entre sigilo futuro (forward secrecy) e a habilidade de se comunicar de forma assíncrona. + +Com o ritmo de crescimento do armazenamento digital e da criptanálise, o sigilo futuro é cada vez mais importante. Caso contrário, qualquer comunicação criptografada que você fizer hoje possivelmente se tornará uma comunicação em texto não cifrado num futuro próximo. + +No caso do email e do bate-papo, existem o OpenPGP para email e o OTR para bate-papo: o primeiro fornece recursos assíncronos e o segundo fornece sigilo futuro, mas nenhum deles possuem ambas as habilidades. Precisamos tanto de uma melhor segurança para email quanto da capacidade de enviar e receber mensagens de bate-papo em modo offline. + +No curto prazo, estamos empilhando transporte de email com sigilo futuro e relay de chat em cima de criptografia tradicional de objetos (OpenPGP). Esta abordagem é idêntica à nossa abordagem paliativa para o problema dos metadados, com o acréscimo de que os servidores repetidores precisam ter a capacidade de não apenas negociar transporte TLS mas também de negociar cifras que suportem sigilo futuro e que evitem uma precarização (downgrade) da cifra utilizada. + +Esta abordagem é potencialmente eficaz contra os observadores externos na rede, mas não obtém sigilo futuro dos próprios prestadores de serviço. + +No longo prazo, pretendemos trabalhar com outros grupos para criar novos padrões de protocolo de criptografia que podem ser tanto assíncronos quanto permitir o sigilo futuro: + + * [Extensões para sigilo futuro para o OpenPGP](http://tools.ietf.org/html/draft-brown-pgp-pfs-03). + * [Handshake Diffie-Hellman triplo com curvas elípticas](https://whispersystems.org/blog/simplifying-otr-deniability/). + +### Problema do grupo + +O problema: + +> Na prática, as pessoas trabalham em grupos, mas a criptografia de chave pública não. + +Temos um monte de ideias, mas não temos ainda uma solução para corrigir este problema. Essencialmente, a questão é como usar primitivas de chaves públicas existentes para criar grupos criptográficos fortes, onde a adesão e as permissões são baseadas em chaves e em listas de controle de acesso mantidas no lado do servidor. + +A maioria dos trabalhos interessantes nesta área tem sido feitos por empresas que trabalham com backup/sincronização/compartilhamento seguro de arquivos, como Wuala e Spideroak. Infelizmente, ainda não há quaisquer protocolos abertos bons ou pacotes de software livre que possam lidar com criptografia para grupos. + +Neste momento, é provável que a melhor abordagem seja a abordagem simples: um protocolo no qual o cliente criptografa cada mensagem para cada destinatário individualmente, e que tenha algum mecanismo para verificação da transcrição de forma a garantir que todas as partes tenham recebido a mesma mensagem. + +Existem alguns trabalhos em software livre com blocos construtivos interessantes que podem ser úteis na construção da criptografia para grupos. Por exemplo: + + * [Re-criptografia de proxy (proxy re-encryption)](https://en.wikipedia.org/wiki/Proxy_re-encryption): permite que o servidor cifre o conteúdo para novos beneficiários sem que tenha acesso ao texto não cifrado. O [gerenciador de lista de discussão SELS](http://sels.ncsa.illinois.edu/) usa OpenPGP para implementar um [sistema inteligente para o proxy de re-encriptação](http://spar.isi.jhu.edu/~mgreen/proxy.pdf). + * [Assinaturas em anel (ring signatures)](https://en.wikipedia.org/wiki/Ring_signature): permite que qualquer membro do grupo assine, sem que se possa saber qual membro fez a assinatura. + +### Problema dos recursos + +O problema: + +> Não existem protocolos abertos que permitam aos usuários compartilharem um recurso de forma segura. + +Por exemplo, ao usar um bate-papo seguro ou rede social segura federada, você precisa de alguma forma de criar links para uma mídia externa, como uma imagem, vídeo ou arquivo, que tenha as mesmas garantias de segurança que a própria mensagem. A incorporação deste tipo de recurso nas mensagens em si é proibitivamente ineficiente. + +Nós não temos uma proposta de como resolver este problema. Há um monte de grandes iniciativas que trabalham sob a bandeira da read-write-web, mas que não levam em conta a criptografia. De muitas maneiras, as soluções para o problema dos recursos são dependentes de soluções para o problema do grupo. + +Tal como acontece com o problema do grupo, a maior parte do progresso nesta área tem sido por pessoas que trabalham em sincronização de arquivos criptografados (por exemplo, estratégias como a Revogação Preguiçosa -- Lazy Revocation -- e Regressão de Chave -- Key Regression). + +### Problema da disponibilidade + +O problema: + +> As pessoas querem alternar suavemente entre dispositivos e restaurar seus dados se perderem um dispositivo, mas isso é bem difícil de se fazer com segurança. + +Os/as usuários/as atuais exigem a capacidade de acessar seus dados em múltiplos dispositivos e de terem em mente que dados não serão perdidos para sempre se perderem um dispositivo. No mundo do software livre, só o Firefox abordou este problema adequadamente e de forma segura (com o Firefox Sync). + +No LEAP, temos trabalhado para resolver o problema de disponibilidade com um sistema que chamamos de [Soledad](/soledad) (um acrônimo em inglês para "sincronização, entre dispositivos, de documentos criptografados localmente"). Soledad dá ao aplicativo cliente um banco de dados de documentos sincronizado, pesquisável e criptografado. Todos os dados são criptografados no lado do cliente, tanto quando ele é armazenado no dispositivo local quanto quando é sincronizado com a nuvem. Até onde sabemos, não há nada parecido com isso, seja no mundo do software livre ou comercial. + +Soledad tenta resolver o problema genérico da disponibilidade de dados, mas outras iniciativas tentaram abordar o problema mais específico das chaves privadas e da descoberta de chaves públicas. Estas iniciativas incluem: + +* [O protocolo proposto por Ben Laurie para armazenamento de segredos na nuvem](http://www.links.org/files/nigori/nigori-protocol-01.html). +* [Código para armazenamento de chaves na nuvem](https://github.com/mettle/nilcat), experimental e similar ao anterior. +* [Comentários de Phillip Hallam-Baker sobre questões similares](http://tools.ietf.org/html/draft-hallambaker-prismproof-key-00). + +### O problema da atualização + +O problema: + +> Quase que universalmente, atualizações de software são feitas de maneiras que são convidativas a ataques e comprometimento de dispositivos. + +O triste estado das atualizações de segurança é especialmente problemático porque os ataques de atualização já podem ser comprados prontos por regimes repressores. O problema de atualização de software é especialmente ruim em plataformas desktop. No caso aplicativos em HTML5 ou para dispositivos móveis, as vulnerabilidades não são tão terríveis, mas os problemas também são mais difíceis de corrigir. + +Para resolver o problema da atualização, o LEAP está adotando um sistema de atualização exclusivo chamado Thandy do projeto Tor. Thandy é complexo para administrar, mas é muito eficaz na prevenção de ataques de atualização conhecidos. + +Thandy, e o projeto relacionado [TUF](https://updateframework.com/), são projetados para dar conta das muitas [vulnerabilidades de segurança em sistemas de atualização de software](https://updateframework.com/projects/project/wiki/Docs/Security) existentes. Num exemplo, outros sistemas de atualização sofrem de uma incapacidade do cliente de confirmar que possuem a cópia mais recente, abrindo assim uma enorme vulnerabilidade onde o atacante simplesmente espera por uma atualização de segurança, evita que o upgrade ocorra e lança um ataque para a exploração da vulnerabilidade que deveria ter acabado de ser corrigida. Thandy/TUF fornecem um mecanismo único para a distribuição e verificação de atualizações de modo que nenhum dispositivo cliente irá instalar a atualização errada ou perder uma atualização sem saber. + +Um problema relacionado com o problema da atualização é o problema do backdoor: como você sabe que uma atualização não tem um backdoor adicionado pelos próprios desenvolvedores do software? Provavelmente, a melhor abordagem é aquela tomada pelo [Gitian](https://gitian.org/), que fornece um "processo de construção determinística para permitir que vários construtores criem binários idênticos". Nós pretendemos adotar o Gitian no futuro. diff --git a/pages/docs/tech/infosec/_table-style.haml b/pages/docs/tech/infosec/_table-style.haml new file mode 100644 index 0000000..c9a3495 --- /dev/null +++ b/pages/docs/tech/infosec/_table-style.haml @@ -0,0 +1,59 @@ +%style + :sass + table.properties + td + vertical-align: top + padding-bottom: 0.75em + th + vertical-align: top + padding-right: 1em + text-align: right + font-weight: normal + font-style: italic + + table.infosec + width: 100% + border-collapse: collapse + tbody + border-top: 1px solid black + border-bottom: 1px solid black + th span.normal + font-weight: normal + th.first, th.second, th.cell + width: 14.285714286% + th.spacer, td.spacer + width: 1px !important + padding: 0 !important + background: black + // border: 1px dotted black + //border: 0 !important + //th.second + // width: 0% + //th.cell + // width: 20% + td.cell + border-top: 1px solid black + border-bottom: 1px solid black + //border-right: 1px dotted rgba(0,0,0,.1) + border-left: 1px dotted rgba(0,0,0,.1) + text-align: center + padding: 4px + &.none + //background-color: #ccc + background: #888 + &.low, &.lower, &.worse + //background-color: #FFCCCC + background: #aaa + &.medium, &.higher + //background-color: #FFFFCC + background: #ccc + &.high, &.better + //background-color: #CCFFCC + background: #e6e6e6 + &.better, &.worse + font-weight: bold + tr.footer td + border-left: 1px dotted rgba(0,0,0,.1) + text-align: center + font-size: 0.8em + diff --git a/pages/docs/tech/infosec/_table.haml b/pages/docs/tech/infosec/_table.haml new file mode 100644 index 0000000..6981dac --- /dev/null +++ b/pages/docs/tech/infosec/_table.haml @@ -0,0 +1,233 @@ +:ruby + table_type = locals[:table_type] + if table_type == :small + ##

Our goal is to actively help providers adopt the LEAP platform, in order to give users more options in the long run. + +%h1#table-notes Decoding the table + +%h2 Communication architectures (columns) + +(to be written) + +%h2 Aspects of information security (rows) + +%p Classical information security consists of a trio of properties: confidentiality, integrity, availability. To this list, others have added authenticity, control, and anonymity (among many others). + +%p For our purposes here, we also add usability, compatibility, and unmappability. What do all these mean? Let's use the example of a single message, and group these nine properties in three categories: + +%h3 Message Security + +%table.properties + %tr + %th Confidentiality + %td A message has highly confidentiality if only the intended recipients are able to read the message. + %tr + %th Integrity + %td A message has high integrity if the recipient is assured the message has not been altered. + %tr + %th Availability + %td A message has high availability if the user is able to get to the message when they so desire. + +%h3 Identity Security + +%table.properties + %tr + %th Authenticity + %td A message has high authenticity if the recipient is certain who sent the message and the sender is certain who received it. + %tr + %th Anonymity + %td A message has high anonymity if the identity of the sender cannot be established by examining the message or the pattern of message delivery. + %tr + %th Unmappability + %td A message has high unmappability if the social network that you communicate with cannot be easily discovered. Unmappability is often collapsed under anonymity. This is unfortunate. It is true the anonymity is one of the issue at stake with social network mapping, but it is just one of many. Because of recent advances in social network analysis and the ability to gather social graph information, we feel that unmappability deserves to be highlighted on its own. + +%h3 User Freedom + +%table.properties + %tr + %th Control + %td If a user is in possession of their own data and can do with it exactly what they want (and others cannot use the data in ways contrary to the wishes of the user), then we say that they have high control. + %tr + %th Usability + %td For a communication system to have high usability, the common user must be able to operate the system in a way that does not compromise their security. + %tr + %th Compatibility + %td For a system to have high compatibility, the user must not be locked into a particular provider or technology, but should have competing and compatible options available to them. In other words, a user's data should be portable and they should have a choice of clients. diff --git a/pages/docs/tech/limitations.md b/pages/docs/tech/limitations.md new file mode 100644 index 0000000..77592f3 --- /dev/null +++ b/pages/docs/tech/limitations.md @@ -0,0 +1,123 @@ +@title = 'Known Limitations' +@toc = true +@summary = 'Known limitations, issues, and security problems with the LEAP platform' + +Herein lie the know limitations, issues, and security problems of the LEAP platform and Bitmask client application. + +Provider problems +========================================== + +Meta-data can be recorded by the provider +------------------------------------------------- + +Currently, the service provider is able to observe the meta-data routing information of messages in transit of their own users (email and chat). This information is not stored, but a nefarious provider could observe this information in transit and record it. + +We have several [plans to eliminate this](/routing), but these are not part of the initial release. + +Incoming cleartext email can be recorded by the provider +--------------------------------------------------------------------- + +Currently, if an incoming email is not already encrypted, the provider encrypts the email to the recipient's public key. + +Potentially, a compromised or nefarious service provider could alter the LEAP software to keep a copy of these cleartext emails. Over time, as more people send encrypted email, this will become less of an issue. Providers will simply see fewer and fewer incoming cleartext emails. + +The provider can undermine the security of the web application +------------------------------------------------------------------------- + +Both the client and the web application use something called SRP (Secure Remote Password) to prevent the server from ever seeing a cleartext copy of the password. This is in contrast to normal password systems, where the password is hashed on the server, so the server could record a copy of the password when it is initially set. + +However, because all the javascript cryptographic libraries used by the user's web browser to perform the SRP negotiation are loaded from the provider's server, a nefarious or compromised provider could give the user's browser bad libraries that secretly sent a cleartext copy of the user's password. + +There are three methods that can be used to prevent this: + +* We could offer the option of first visiting a third party website that loads the authentication libraries before redirecting to the provider's website. Unfortunately, this user experience is a bit awkward. +* We could allow providers the option of not allowing authentication or signup through the webapp. Instead, the client could authenticate with the provider's session API, receiving a session token, and then pass this token to the web browser. +* Currently, the web application is needed for email settings, help tickets and billing, but potentially these functions could be rolled into the Bitmask client. + +It is not either/or, we could support a combination of options. + +The details for both of these are bit more tricky than in these simple descriptions, because of the need to work around the single origin policy, but it is still entirely possible to do this securely (using either CORS or PostMessage). + +Still possible to brute force the password verifier +----------------------------------------------------------------- + +SRP (Secure Remote Password) does not store a hash of the password in the provider's user database, but instead a password verifier. However, if an attacker gains access to the database of password verifiers (plus salts) they can perform a brute force attack similar to a normal attack on a database of password hashes. The attack in the case of SRP is more difficult, since there is much more cryptographic work involved, but it is still possible. + +To mitigate exposure of the password verifiers, we plan to separate them out into a separate database with only a separate single-purpose authentication API daemon granted access. Additionally, we hope to offer a password-less option that uses OpenPGP smart cards. + +The provider can observe VPN traffic +-------------------------------------------------- + +The "Encrypted Internet" feature of LEAP currently works using OpenVPN secure tunnel to proxy all network traffic to a gateway operated by the provider. Once the traffic exits this gateway, it is cleartext (unless otherwise encrypted on the client, e.g. HTTPS) and could be observed and record by the provider, or any network observer able to monitor all traffic into and out of the gateway. + +This limitation is mitigated by having the LEAP client authenticate with the VPN gateway using semi-anonymous or anonymous client certificates. A nefarious or compromised provider could attempt to record the moment that a user fetches a new client certificate, and record the IP address or authentication credentials of the user at that time. + +In the future, we plan to remove this vulnerability in two ways: + +* Allow the client to fetch new client certificates using blind signatures, so that there is no way for the provider to associate user with certificate, but we can also ensure that only valid users get client certificates. +* Use Tor as an alternate and optional transport for "Encrypted Internet". From the stand point of the user, it would work the same (using perhaps tun socks proxy and dnscrypt-proxy). This option would be slower and not support UDP traffic, but it would be much more secure. The Tor project prefers that every application that uses Tor be specifically designed for Tor so that it does not leak information in other ways. Using Tor as a default route like we do with OpenVPN would violate this, but would be more user friendly. + +Device problems +================================== + +A compromised device is a sad device +---------------------------------------------- + +The LEAP client tries to minimize attacks related to physical access to the device. In particular, we try to be very resistant to offline attacks, where an attacker has captured the user's device while the LEAP client does not have an open session. For example, locally stored data is kept in an encrypted database that is only unlocked when the user authenticates with the application. + +However, if an attacker gains access to the device, and then the device is returned to the user, they can do all kinds of nasty things, like install a keylogger that captures every keystroke. + +This vulnerability is true of all software, not just LEAP, but it is worth noting. + +Mail clients cache data in cleartext +-------------------------------------------------- + +Currently, LEAP relies on the use of a standard email client like Thunderbird, Apple Mail, or Outlook. Although all LEAP data is stored encrypted on the user's device, these mail clients cache and index email data in the clear on their own. + +To fix this problem, we have two plans: + +* Write plugins for Thunderbird, Apple Mail, and Outlook to make the integration with the Bitmask client more easy and to automatically configure the email client to not-cache or index. +* Distribute a custom email client with the Bitmask application, perhaps based on mailpile. + +The Bitmask application provides a client-encrypted searchable database, so it should be possible to get the same functionality provided by the indexing done by the existing mail clients. + +User problems +================================= + +Passwords are never going to be very good +--------------------------------------------------- + +LEAP relies on the user's password to unlock access to the user's client encrypted data storage. It does this the right way, using a solid KDF, but many users choose passwords that are weak, offering marginal security if an attacker gains offline access to the user's encrypted storage (for example, if they obtain the device). + +In the future, we hope to add support for OpenPGP smart cards in order to overcome many of the problems associated with passwords. + +Design problems +============================================ + +Enumeration of usernames +----------------------------- + +The system LEAP uses to validate the public keys of users is inherently vulnerable to an attacker enumerating usernames. Because requests for public keys may be proxy'ed through other providers, there is no good method of preventing an attacker from launching many queries for public keys and eventually mapping most of the usernames. + +This is unfortunate, but this is also a problem with all other such systems of key discovery and validation (i.e. DANE). For now, we consider this to be an acceptable compromise. + +Much trust is placed in LEAP +------------------------------------------- + +In order to shield the service provider from being pressured by a host government or criminal organization to add a backdoor into the client, the model with the LEAP platform is that the client is normally downloaded from the leap.se website and subsequent updates are signed by LEAP developers. + +This is good for the provider, but not so good for LEAP, since this system could potentially place pressure on LEAP. Because LEAP does not have a provider-customer relationship with any user, LEAP cannot target compromised applications for particular users. LEAP could, however, introduce a backdoor in the client used by all users. + +To prevent this, we plan to adopt [Gitian](https://gitian.org/) or something equivalent. Gitian allows for a way to standardize the entire build environment and build process in order for third parties to be able to verify that the released binary application does indeed match the correct source code. + +External authority problems +================================================= + +Certificate authorities considered dangerous +--------------------------------------------------- + +The long term goal with LEAP is to entirely rid ourselves of reliance on the x.509 certificate authority system. However, there are a few places where the platform still relies on it: + +* When the client first validates a new provider, it will assume the provider's TLS connection is valid if presented with a server certificate signed by a commercial CA recognized by the operating system. Subsequent connections to the provider's API use pinned certificates. +* When a nicknym agent discovers new public keys for users, it uses a TLS connection validated by a commercial CA recognized by the operating system. In the future, nicknym responses will also be signed, eliminating some of the vulnerability. +* Currently, the web application does not get deployed with any other TLS validation than the standard commercial CA method. Eventually, we plan to support [DNS-based Authentication of Named Entities (DANE)](https://datatracker.ietf.org/wg/dane/), [Trust Assertions for Certificate Keys (TACK)](http://tack.io/), [Public Key Pinning Extension for HTTP](https://datatracker.ietf.org/doc/draft-ietf-websec-key-pinning/), or [Certificate Transparency](http://www.certificate-transparency.org/) (whatever gets the most traction). diff --git a/pages/docs/tech/routing.md b/pages/docs/tech/routing.md new file mode 100644 index 0000000..46af93f --- /dev/null +++ b/pages/docs/tech/routing.md @@ -0,0 +1,65 @@ +@title = "Graph Resistant Routing" +@summary = "LEAP's plans for protecting routing meta-data" + +# A social graph is highly sensitive data + +As messages are sent and delivered, they contain "meta-data" describing where these messages should be routed. With existing protocols for email and chat, this meta-data is sent in the clear and can be used to build a social graph of how people interact. + +As the field of network analysis has advanced in recent years, the social graph has become highly sensitive and critical information. Knowledge of the social graph can give an attacker a blueprint into the inner workings of an organization or reveal surprisingly intimate personal details, such as sexual orientation or even health status. + +In the short term, LEAP is opportunistically encrypting the message transport whenever possible. This protects the meta-data routing information from an external observer, but does not protect against a nefarious or compromised service provider. This page is about our plans for a better way. + +# Possible solutions + +There are four strategies we might employ to add protection of routing information to email and chat: + +* Auto-alias-pairs: Each party auto-negotiates aliases for communicating with each other. Behind the scenes, the client then invisibly uses these aliases for subsequent communication. The advantage is that this is backward compatible with existing routing. The disadvantage is that the user's server stores a list of their aliases. As an improvement, you could add the possibility of a third party service to maintain the alias map. +* Onion-routing-headers: A message from user A to user B is encoded so that the "to" routing information only contains the name of B's server. When B's server receives the message, it unwraps (unencrypts) a supplementary header that contains the actual user "B". Like aliases, this provides no benefit if both users are on the same server. As an improvement, the message could be routed through intermediary servers. +* Third-party-dropbox: To exchange messages, user A and user B negotiate a unique "dropbox" URL for depositing messages, potentially using a third party. To send a message, user A would post the message to the "dropbox". To receive a message, user B would regularly polls this URL to see if there are new messages. +* Mixmaster-with-signatures: Messages are bounced through a mixmaster-like set of anonymization relays and then finally delivered to the recipient's server. The user's client only displays the message if it is encrypted, has a valid signature, and the user has previously added the sender to a 'allow list' (perhaps automatically generated from the list of validated public keys). +* Direct-delivery: Instead of relaying messages from client to server to server to client, in this model the sender's client delivers the message directly to the recipient's server. This delivery would need to happen over an anonymization network akin to Tor, or through proxies set up for this purpose. In order to prevent spam, the recipient server would only accept messages delivered in this manner if the message was signed using a group signature (this ensures that the server doesn't know who the sender is, but can confirm that they are allowed to deliver to a particular user). This would require advanced confirmation on the part of both users that they may send messages to one another. This is how Pond works. + + +None of these are currently used for email or chat. + +# Auto alias pairs + +How would auto alias pairs work? Imagine users Alice and Bob. Alice wants to correspond with Bob but doesn't want either her service provider or Bob's service provider to be able to record the association. She also doesn't want a network observer to be able to map the association. + +When Alice first sends a message to Bob, Alice's client will initiate the following chain of events on her behalf, automatically and behind the scenes. + +* Alice's client requests a new alias from her service provider. If her normal address is alice@domain.org, she receives an alias hjj3fpwv84fn@domain.org that will forward messages to her account. +* Alice's client uses automatic key discovery and validation to find Bob's public key and discover if Bob's service provider supports map resistant routing. +* If Bob does support it, Alice's client will then send a special message, encrypted to Bob's key, that contains Alice's public address and her private alias. +* When Bob's client encounters this special message, it records a mapping between Alice's public address (alice@domain.org) and the private alias she has created for Bob's use (hjj3fpwv84fn@domain.org). +* Bob's client then creates an alias for Bob and sends it to Alice. +* Alice's client receives this alias, and records the mapping between Bob's public address and his private alias. +* Alice's client then relays the original message to Bob's alias. + +Subsequently, whenever Alice or Bob want to communicate, they use the normal public addresses for one another, but behind the scenes their clients will rewrite the source and recipient of the messages to use the private aliases. + +This scheme is backwards compatible with existing messaging protocols, such as SMTP and XMPP. + +## Limitations + +There are five major limitations to this scheme: + +1. **Alias unmasking attacks:** because each service provider maintains an alias map for their own users, an attacker who has gained access to this alias map can de-anonymize all the associations into and out of that particular provider, for the past and future. +2. **Timing attacks:** a statistical analysis of the time that messages of a particular size are sent, received, and relayed by both service providers could reveal the map of associations. +3. **Log correlation problem:** a powerful attacker could gain access to the logs of both service providers, and thereby reconstruct the associations between the two providers. +4. **Single provider problem:** this scheme does not protect associations between people on the same service provider. +5. **Client problem:** if the user's device is compromised, the record of their actual associations can be discovered. + +At this point, we feel that it is OK to live with these limitations for the time being in order to simply the logic of the user's client application and to ensure backward compatibility with existing messaging protocols. + +Possible future enhancements could greatly mitigate these attacks: + +* We could use temporarily aliases that rotate daily, perhaps based on an HMAC counter, based on a shared secret between two users. +* The 'alias service' could be run by a third party, so that providers don't have access to the alias maps (thus migitating problems 1, 3, and 4). +* A service provider with sufficient traffic could be in a very good position to be able to aggregate and time-shift the messages it relays in order to disrupt timing attacks. + +Ultimately, however, most of these attacks are a problem when faced with an extremely powerful adversary. This scheme is not designed for these situations. Instead, it is designed to prevent the casual, mass surveillance of all communication that currently takes place in repressive and democratic countries alike, by both governments and corporations. It greatly reduces the capacity for association mapping of both traffic over the wire and in stored communication. It is not designed to make a particular user anonymous when specifically targeted by a powerful adversary. + +# How would X work? + +How would onion-routing-headers, third-party-dropbox, or mixmaster-with-signatures work?

These problems are hard, and have defied easy solutions, because there are no quick technological fixes: at issue is the complex interaction between user experience, real world infrastructure, and security. Although no consensus has yet emerged on how best to tackle any of these problems, the diversity of projects listed in this report reflect an surge of interest in this area and an encouraging spirit of experimentation. + +<a name="key-management"></a>Key Management +----------------------------------------------------------- + +All the projects in this report use public-key encryption to allow a user to send a confidential message to the intendant recipient, and for the recipient to verify the authorship of the message. Unfortunately, public-key encryption is notoriously difficult to use properly, even for advanced users. The very concepts are confusing for most users: public key versus private key, key signing, key revocation, signing keys versus encryption keys, bit length, and so on. + +Traditionally, public key cryptography for email has relied on either the X.509 Certificate Authority (CA) system or a decentralized "Web of Trust" (WoT) for key validation (authenticating that a particular person owns a particular key). Recently, both schemes have come under intense criticism. Repeated security lapses at many of the Certificate Authorities have revealed serious flaws in the CA system. On the other hand, in an age where we better understand the power of social network analysis and the sensitivity of the social graph, the exposure of metadata by a "Web of Trust" is no longer acceptable from a security standpoint. + +This is where we are now: we have public key technology that is excessively difficult for the common user, and our only methods of key validation have fallen into disrepute. The projects listed here have plunged into this void, attempting to simplify the usage of public-key cryptography. These efforts have four elements: + +* Key discovery: There is no commonly used standard for discovering the public key attached to a particular email address. All the projects here that use OpenPGP intend to initially use, as a stop-gap measure, the OpenPGP keyservers for key discovery, although the keyserver infrastructure was not designed to be used in this way. +* Key validation: If not Certificate Authorities or Web of Trust, what then? Nearly every project here uses Trust On First Use (TOFU) in one way or another. With TOFU, a key is assumed to be the right key the first time it is used. TOFU can work well for long term associations and for people who are not being targeted for attack, but its security relies on the security of the discovery transport and the application's ability to retain a memory of discovered keys. TOFU can break down in many real-world situations where a user might need to generate new keys or securely communicate with a new contact. The projects here are experimenting with TOFU in different ways, and these problems can likely be mitigated by combining TOFU with other measures. +* Key availability: Almost every attempt to solve the key validation problem turns into a key availability problem, because once you have validated a public key, you need to make sure that this validation is available to the user on all the possible devices they might want to send or receive messages on. +* Key revocation: What happens when a private key is lost, and a user want to issue a new public key? None of the projects in this report have an answer for how to deal with this in a post-CA and post-WoT world. + +The projects that use a public key as a unique identifier do not have the key validation problem, because they do no need to try to bind a human memorable identifier to a long non-memorable public key: they simply enforce the use of the public key as the user's address. For example, rather than `alice@example.org` as the identifier, these systems might use `8b3b2213ff00e5fb684b003d005ed2fb`. In place of the key validation problem, this approach raises the key exchange problem: how do two parties initially exchange long public keys with one another? This approach is taken by all the P2P projects listed here (although there do exist some P2P application that don't use public key identifiers). + +Some of the major experimental approaches to solving the problem of public key discovery and validation include: + +1. Inline: Many of the projects here plan to simply include the user's public key as an attachment to every outgoing email (or in a footer or SMTP header). +1. DNS: Key distributed via DNSSEC, where a service provider adds a DNS entry for each user containing the user's public key or fingerprint. +1. Append-only log: Proposal to modify Certificate Transparency to handle user accounts, where audits are performed against append-only logs. +1. Network perspective: Validation by key endorsement (third party signatures), with audits performed via network perspective. +1. Introductions: Discovery and validation of keys through acquaintance introduction. +1. Mobile: Although too lengthy to manually transcribe, an app on a mobile device can be used to easily exchange keys in person (for example, via a QR code or bluetooth connection). + +<a name="metadata-protection"></a>Metadata Protection +----------------------------------------------------------- + +Traditional schemes for secure email have left metadata exposed. We now know that metadata is often more sensitive than message content: metadata is structured data, easily stored forever, and subject to powerful techniques of social network analysis that can can be incredibly revealing. + +Metadata protection, however, is **hard**. In order to protect metadata, the message routing protocol must hide the sender and recipient from all the intermediaries responsible for relaying the message. This is not possible with the traditional protocol for email transport, although it will probably be possible to piggyback additional (non-backward compatible) protocols on top of traditional email transport in order to achieve metadata protection. + +Alternately, some projects reject traditional email transport entirely. These decentralized peer-to-peer approaches to metadata protection generally fall into four camps: (1) directly relay the message from sender's device to recipients device; (2) relay messages through a network of friends; (3) broadcast messages to everyone; (4) relay messages through an anonymization network such as Tor. The first two approaches protect metadata, but at the expense of increasing vulnerability to traffic analysis that could reveal the same metadata. The third solution faces serious problems of scalability. Pond uses the fourth method, discussed below. + +All schemes for metadata protection face the prospect of increasing Spam (since one of the primary methods used to prevent Spam is analysis of metadata). This is why some schemes with strong metadata protection make it impossible to send or receive messages to anyone you are not already in contact with. This works brilliantly for reducing Spam, but is unlikely to be a viable long term strategy for entirely replacing the utility of email. + +<a name="forward-secrecy"></a>Forward Secrecy +----------------------------------------------------------- + +Forward secrecy is a security property that prevents an attacker from saving messages today and then later decrypting these messages once they have captured the user's private key. Without forward secrecy, an attacker is more likely to be able to capture messages today and simply wait for computers to become powerful enough to crack the encryption by brute force. Traditional email encryption offers no forward secrecy. + +All methods for forward secrecy involve a process where two parties negotiate an ephemeral key that is used for a short period of time to secure their communication. In many cases, the ephemeral key is generated anew for every single message. Traditional schemes for forward secrecy are incompatible with the asynchronous nature of email communication, since with email you still need to be able to send someone a message even if they are not online and ephemeral key generation requires a back and forth exchange between both parties. + +There are several new experimental (and tricky) protocols that attempt to achieve both forward secrecy and support for asynchronous communication, but none have yet emerged as a standard. These protocols either (1) require an initial bootstrap message that is not forward secret, (2) require an initial synchronous exchange to start the process, or (3) rely on a pool of pre-generated ephemeral key pairs that can be used on first contact. When the continually changing ephemeral key for a conversation is lost by either party, then the initialization stage is performed again. + +Another possible approach is to use traditional encryption with no support for forward secrecy but instead rely on a scheme for automatic key discovery and validation in order to frequently rotate keys. This way, a user could throw away their private key every few days, achieving a very crude form of forward secrecy. + +<a name="data-availability"></a>Data Availability +----------------------------------------------------------- + +Users today demand data availability: they want to be able to access their messages and send messages from any device they choose, wherever they choose, and whenever they choose. Most importantly, they don't want the loss of any particular device to result in a loss of all their data. For insecure communication, achieving data availability is dead simple: simply store everything in the cloud. For secure communication, however, we have no proven solutions to this problem. As noted above, the key management problem is also really a data availability problem. + +Most of the email projects here have postponed dealing with the data availability problem. A few have used IMAP to synchronize data or developed their own secure synchronization protocol. Several of the email-like P2P approaches rely on a P2P network for data availability. + +<a name="secure-authentication"></a>Secure Authentication +----------------------------------------------------------- + +For those projects that make use of a service provider, one of the key problems is how to authenticate securely with the service provider without revealing the password (since the password is probably also used to encrypt the private key and other secure storage, so it is important that the service provider does not have cleartext access as with typical password authentication schemes). The possible schemes include: + +* Separate passwords. The application can use one password for authentication and a separate password for securing secrets. +* Pre-hash the password on the client before sending it to the server. This method can work, although it does not also authenticate the server (an impostor server can always reply with a success message), and is still vulnerable to brute force dictionary attacks. +* Use Secure Remote Password (SRP), a type of cryptographic zero-knowledge proof designed for password authentication in which the client and server mutually authenticate. SRP has been around a while, and is fairly well analyzed, but it is still vulnerable to brute force dictionary attacks (albeit much less than traditionally password schemes). +* Sign a challenge from the server with the user's private key. This has the advantage of being nearly impossible to brute force attack, but is vulnerable to impostor server providers and requires that the user's device has the private key. + +No consensus or standard has yet emerged, although SRP has been around a while. + +<a name="web-mail"></a>Web Mail +=========================================================== + +Most users are familiar with web-based email and the incredible convenience it offers: you can access your email from any device, and you don't need to worry about data synchronization. Developers of web-based email faces several difficult challenges when attempting to make a truly secure application. These challenges can be overcome, but not easily. + +First, because the web application is loaded from the web server each time you use it, the service provider could be targeting a version of the client to you that includes a backdoor. To overcome this vulnerability, it is possible to load the code for the web application from a third party. There are two ways of doing this: + +1. App Store: Most web browsers support special extensions in the form of "Browser Applications". These are loaded from some kind of app store and installed on the user's device. In this case, the third party that provides the application is the app store. Therefore, the user is then relying on the app store to furnish them with a secure version of the app. For example, this is the approach taken by [cryptocat](https://crypto.cat). +2. Third Party: There are two advanced mechanisms to allow a web application to be loaded from one website and allow it to access data from another website. One is called CORS ([Cross-origin resource sharing](https://en.wikipedia.org/wiki/Cross-origin_resource_sharing)) and the other is HTML5's [window.postMessage command](https://developer.mozilla.org/en-US/docs/Web/API/window.postMessage). With either method, anyone can be the third party furnishing the application, or it can be self hosted. For example, this is the approach taken by [Unhosted](https://unhosted.org). + +Second, even if the application is loaded from a trusted third party, web browsers are not an ideal environment for sensitive data: there are many ways for an in-browser application to leak data and web browsers are notoriously prone to security holes (it is a very difficult problem to be able to run untrusted code locally in a secure sandbox). To their credit, the browser developers are often vigilant about fixing these holes (depending on who you ask), but the browser environment is far from a secure computing environment. It continues to be, however, the most convenient environment. + +Third, developers of web-based secure email face an additional challenge when dealing with offline data or data caching. Modern HTML5 apps typically store a lot of data locally on the user's device using the localStorage facility. Currently, however, no browser stores this encrypted. A secure web-based email application must either choose to not support any local storage, or develop a scheme for individually encrypting each object put in localStorage, a process which is very inefficient. Even storing keys temporarily in short lived session storage is problematic, since these can be easily read from disk later. + +These challenges to do not apply to downloaded mail clients that happen to use HTML5 as their interface (Mailpile, for example). + +<a name="lavaboom"></a>Lavaboom +----------------------------------------------------------- + +[lavaboom.com](https://www.lavaboom.com) + +Lavaboom is a new web-based mail provider from Germany using client-side encryption in the browser.

Many in the press have [said GCHQ forced the closure](http://www.ibtimes.co.uk/articles/529392/20131211/gchq-forced-privatesky-secure-email-service-offline.htm), which the [company refutes](http://www.certivox.com/blog/bid/359788/The-real-story-on-the-PrivateSky-takedown). + +<a name="startmail"></a>StartMail +----------------------------------------------------------- + +[startmail.com](http://startmail.com) + +The makers of the secure search engine [startpage.com](https://startpage.com) have announced they will be providing secure email service. + +Despite the tag line as the "world's most private email," StartMail is remarkably insecure. It offers regular IMAP service and a webmail interface that supports OpenPGP, but the user still must trust StartMail entirely. For example when you authenticate, your password string is sent to StartMail, and new OpenPGP keypairs are generated on the server, not the client. The website also makes some dubious statements, such as claiming to be more secure because their TLS server certificate supports extended validation. + +Verdict: oil of snake + +<a name="scramble"></a>Scramble +----------------------------------------------------------- + +[scramble.io](https://scramble.io) + +Scramble is an OpenPGP email application that can be loaded from a website (with plans to add app store support).

The server never sees the user's passphrase (password is hashed using scrypt before sent to the server during account creation and authentication).

Keys are validated using notaries. + +**Infrastructure:** Scramble uses a system of network perspectives to discover and validate public keys.

Traditional examples of email clients include Thunderbird or Microsoft Outlook (although both these application include a lot of other functionality as well). Nearly all email clients communicate with the email service provider using IMAP or POP and SMTP, although some also support local mailboxes in mbox or Maildir format. + +There are two primary advantages to the mail client approach: + +1. Existing accounts: By using a custom secure mail client, a user can continue to use their existing email accounts. +1. Tailored UI: A custom client has the potential to rethink the email user experience in order to better convey security related details to the user. + +The mail client approach, however, also has several disadvantages: + +1. Insecure service providers: A mail client cannot address many of the core problems with email security when used with a traditional email provider. For example, metadata will not be protected in storage or transit, and the provider cannot aid in key discovery or validation. Most importantly, many existing mail providers are highly vulnerable, since few rely on DNSSEC for their MX records or validate their StartTLS connections for mail relay (when they even bother to enable StartTLS). A traditional email provider also requires authentication via password that is seen by the provider in clear text, and might be recorded by them. Finally, most service providers retain significant personally identifiable information, such as IP address of clients. +1. Install a new app: As with many of the other approaches, the custom mail client approach requires that users download and install a specialized application on their device before they can use it. + +Ultimately, the level of email security that is possible with the custom mail client approach will always be limited. However, custom email clients may be an excellent strategy for gradually weening users away from email and to a different and more secure protocol. Most of the projects in this section see email support as a gateway to ease the transition to something that can replace email. + +<a name="bitmail"></a>Bitmail +----------------------------------------------------------- + +[bitmail.sf.net](http://bitmail.sf.net) + +Bitmail is a desktop application that provides a user interface for traditional IMAP-based mail, but also supports a custom peer-to-peer protocol for relaying email through a network of friends.

The initial focus is on email, with plans to eventually support post-email protocols like bitmessage, flowingmail, or darkmail. Also, the developers hope to add support for XMPP-based chat in the future. Since the Mozilla foundation has not committed the resources necessary to keep Thunderbird contemporary, the Mailpile initiative holds a lot of promise as a cross-platform mail client that seeks to redesign how we interact with email. + +**Keys:** Mailpile email encryption is based on OpenPGP (it uses your GPG keyring). Key discovery will be handled using OpenPGP keyservers and including public keys as attachments to outgoing email. Public keys are trusted on first use, with plans for validation via DANE and manual fingerprint verification (future support for a P2P protocol might include additional methods, such as Certificate Transparency or Short Authentication Strings). Currently, keys are not backed up. + +**Application:** Mailpile UI is written using HTML5 and Javascript, running against a self-hosted Python application (that typically lives locally on the device, but might be running on your own server). + +**Limitations:** Mailpile does not currently have a scheme for recovery if your device is destroyed or a method for securely synchronizing keys among devices. Although the search index is stored encrypted on disk (if the user already has GPG installed and a key pair generated), it is encrypted in a way that requires the index to be loaded entirely into memory.

The key idea with self-hosted email is to cut out the middleman and run your own email server. + +In the United States, much of the interest in self-hosted email is driven by the Supreme Court's current (and particularly odd) interpretation of the 4th amendment called the ["Third-Party Doctrine"](https://en.wikipedia.org/wiki/Third-Party_Doctrine). Essentially, you have much weaker privacy protections in the US if you entrust any of your data to a third party. Additionally, the Court has so far afforded much greater protections to items physically inside your home. "Aha!" say the hackers and the lawyers, "we will just put email in the home." + +Unfortunately, it is not so simple. There are some major challenges to putting email servers in everyone's home: + +* **Delegated reputation**: The current email infrastructure is essentially a system of delegated reputation. In order to be able to send mail to most providers and not have a large percentage of it marked as Spam, a service provider must gradually build up a good reputation. Users are able to send mail because their provider has cultivated this reputation and maintained it by closing abusive accounts. It is certainly possible to run an email provider with a single user, but it is much harder to build up a good reputation. Also, many email providers block all relay attempts from IP addresses that have been flagged as "home" addresses, on the (probable) assumption that the message is coming from a virus and not a legitimate email server. +* **Servers are on a hostile network**: Because a server needs to have open ports that are publicly accessible from the internet at all times, running one is much trickier than a simple desktop computer. It is much more critical to make sure security upgrades are applied in a timely manner, and that you are able to respond to external attacks, such as "Spam Bombs". Any publicly addressable IP that is put on the open internet will be continually probed for vulnerabilities. Self-hosting will probably work great for a protocol like Pond, where there are strict restrictions on who may deliver incoming messages. Email, however, is a protocol that is wide open and prone to abuse. +* **Sysadmins are not robots**: No one has yet figured out how to make self-healing servers that don't require a skilled sysadmin to keep them healthy. Once someone does, a lot of sysadmins will be out of work, but they are presently not very worried. There are many things that commonly go wrong with servers, such as upgrades failing, drives filling up, daemons crashing, memory leaks, hardware failures, and so on. +* **Does not address the important problems**: Moving the physical location of a device does nothing to solve the hard problems associated with easy-to-use email security (such as data availability and key validation). Some of the approaches to these problems rely on service provider infrastructure that would be infeasible to self host. +* **DNS is hard**: One of the important security problems with traditional email is the vulnerability MX DNS records. Doing DNS correctly is hard, and not something that can be expected of the common user. + +Self-hosted email is an intriguing "legal hack", albeit one that faces many technical challenges. + +<a name="self-hosted-dark-mail"></a>Dark Mail Alliance +----------------------------------------------------------- + +The Dark Mail Alliance has said they want to support self-hosting for the server component of the system.

By modifying how both email clients and email servers work, these projects have the potential to deploy greater security measures than are possible with a client-only approach. For example: + +* Encrypted relay: A secure email provider is able to support, and enforce, encrypted transport when relaying mail to other providers. This is an important mechanism for preventing mass surveillance of metadata (which is otherwise not protected by OpenPGP client-side encryption of message contents). +* Easier key management: A secure email provider can endorse the public keys of its users, and provide assistance to various schemes for automatic validation. Additionally, a secure email provider, coupled with a custom client, can make it easy to securely manage and back up the essential private keys which are otherwise cumbersome for most users to manage. +* Invisible upgrade to better protocols: A secure email provider has the potential to support multiple protocols bound to a single user@domain address, allowing automatic and invisible upgrades to more secure post-email protocols when both parties detect the capability. +* A return to federation: The recent concentration of email to a few giant providers greatly reduces the health and resiliency of email as an open protocol, since now only a few players essentially monopolize the medium. Projects that seek to make it easier to offer secure email as a service have the potential to reverse this trend. +* Secure DNS: A secure provider can support DNSSEC and DANE, while most other email providers are unlikely to anytime soon. This is very important, because it is easy to hijack the MX records of a domain without DNSSEC. +* Minimal data retention: A service provider that follows "best practices" will choose to retain less personally identifiable information on their users, such as their home IP addresses. + +The goal of both projects in this category is to build systems where the service provider is untrusted and cannot compromise the security of its users. + +Despite the potential of this approach, there are several unknown factors that might limit its appeal: + +* In order to benefit from a more secure provider, a user will need to switch their email account and email address, a very high barrier to adoption. +* Where once there were many ISPs that offered email service, it is no longer clear if there is either the demand to sustain many email providers or the supply of providers interested in offering email as a service. +* Users must download and install a custom application. + +<a name="dark-mail-alliance"></a>Dark Mail Alliance +----------------------------------------------------------- + +[darkmail.info](https://darkmail.info) + +The Dark Mail Alliance will include both a client application and server software. The plan is to support traditional encrypted email (both OpenPGP and S/MIME), a new federated email-like protocol adapted from SilentCircle's instant message protocol (SCIMP), and a pure peer-to-peer messaging protocol. Both the client and server will be made available as free software. + +**Keys:** Key pairs will be generated on the user's device and uploaded to the service provider. [Certificate Transparency](http://certificate-transparency.org) will be used to automatically validate the service provider's endorsement of these public keys. Dark Mail additionally plans to support fingerprint confirmation, short authentication strings, and shared secret for manual key validation.

Currently, this includes user registration and management, help tickets, billing, VPN service, and secure email service. The secure email service is based on OpenPGP. + +**Keys:** Key pairs are generated on the user's device. Keys, and all user data, are stored in a client-encrypted database that is synchronized among the user's devices and backed up to the service provider. Keys are automatically validated using a combination of provider endorsement and network perspective (coming soon). Keys are discovered via the OpenPGP keyservers, the OpenPGP header, email footers, and a custom HTTP-based discovery protocol. + +**Infrastructure:** LEAP follows a traditional federated client/server architecture. The client is designed to work with any LEAP-compatible service provider (with plans to support legacy IMAP providers in the future). For security reasons, users are encouraged to get the application from LEAP and not their service provider. + +**Application:** The client application works with any existing MUA by exposing a local IMAP/SMTP server that the MUA can connect to. There is a Thunderbird extension to automate configuration of the account in Thunderbird. The client application communicates with the service provider using a custom protocol for synchronizing encrypted databases. The application is a very small C program that launches the Python code. The user interface is written using Qt. + +**Limitations:** In the current implementation, security properties of forward secrecy and metadata production are not end-to-end. Instead, the client relies on the service provider to ensure these properties. This limitation is due to some inherent limitations in the existing protocols for secure email. As with many of the other projects, LEAP's plan is to invisibly upgrade to a post-email protocol when possible in order to overcome these limitations. + +* Written in: Python +* Source code: https://leap.se/source +* Design documentation: https://leap.se/docs +* License: mostly GPL v3, some MIT and AGPL. + +<a name="post-email-alternatives"></a>Post-email alternatives +=========================================================== + +There are several projects to create alternatives to email that are more secure yet still email-like. + +These projects share some common advantages: + +1. **Trust no one:** These projects share an approach that treats the network, and all parties on the network, as potentially hostile and not to be trusted. With this approach, a user's security can only be betrayed if their own device is compromised or the software is flawed or tampered with, but the user is protected from attacks against any service provider (because there typically is not one). +1. **Fingerprint as identifier:** All these projects also use the fingerprint of the user's public key as the unique routing identifier for a user, allowing for decentralized and unique names. This neatly solves the problem of validating public keys, because every identifier basically *is* a key, so there is no need to establish a mapping from an identifier to a key. + +Except for Pond, all these alternatives take a pure peer-to-peer approach. As such, they face particular challenges: + +1. **The "Natural" Network**: Many advocates of peer-to-peer networking advance the notion that decentralized networks are the most efficient networks and are found everywhere in nature (in the neurons in our brain, in how mold grows, in how insects communicate, etc). This notion is only partially true. Networks are found in nature, but these network are not radically decentralized. Instead, natural networks tend to follow a power law distribution (aka "[scale free networks](https://en.wikipedia.org/wiki/Scale-free_network)"), where there is a high degree of partial centralization that balances "brokerage" (ability to communicate far in the network) with "closure" (ability to communicate close in the network). Thus, in practice, digital networks rely on "super hubs" that process most of the traffic. These hubs need to be maintained and hosted by someone, often at great expense (and making the network much more vulnerable to Sybil attacks). +1. **The Internet:** Sadly, the physical internet infrastructure is actually very polycentric rather than decentralized (more akin to a tree than a spider's web). One reason for the rise of cloud computing is that resources are much cheaper near the core of the internet than near the periphery. Technical strategies that attempt to leverage the periphery will always be disadvantaged from an efficiency standpoint. +1. **Traffic Analysis:** Most of the peer-to-peer approaches directly relay messages from sender's device to recipient's device, or route messages through the participant's contacts. Such an approach to message routing makes it potentially very easy for a network observer to map the network of associations, even if the message protocol otherwise offers very strong metadata protection. +1. **Sybil Attacks:** By their nature, peer-to-peer networks do not have a method of blocking participation in the network. This makes them potentially very vulnerable to [Sybil attacks](https://en.wikipedia.org/wiki/Sybil_attack), where an attacker creates a very large number of fake participants in order to control the network or reveal the identity of other network participants. +1. **Mobile:** Peer-to-peer networks are resource intensive, typically with every node in the network responsible for continually relaying traffic and keeping the network healthy. Unfortunately, this kind of thing is murder on the battery life of a mobile device, and requires a lot of extra network traffic. +1. **Identifiers**: Using key fingerprints as unique identifiers has some advantages, but it also makes user identifiers impossible to remember. There is a lot of utility in the convenience of memorable username handles, as evidence in the use of email addresses and twitter handles. +1. **Data Availability**: Unless also paired with a cloud component, peer-to-peer networks have much lower data availability than other approaches. For example, it takes much longer to update message deliveries from a peer network than from a server, particularly when the device has been offline for a while. Also, if a device is lost or destroyed, generally the user loses all their data. + +Most of these challenges have possible technological solutions that might make peer-to-peer approaches the most attractive option in the long run. For example, researchers may discover ways to make P2P networks less battery intensive. For this reason, it is important that research continue in this area. However, [in the long run we are all dead](https://en.wikiquote.org/wiki/John_Maynard_Keynes) and peer-to-peer approaches face serious hurdles before they can achieve the kind of user experience demanded today. + +<a name="bitmessage"></a>Bitmessage +----------------------------------------------------------- + +[Bitmessage](https://bitmessage.org) + +Bitmessage is a peer-to-peer email-like communication protocol.

It acts as secure proxy, providing VPN, and communication services analogous to email and VoIP. In order to communicate with another user, they must also have an enigmabox. + +Data is routed peer-to-peer directly from one enigmabox to another using cjdns, a system of virtual mesh networking in which IP addresses are derived from public keys. End to end encryption of messages is provided entirely by the cjdns transport layer. + +With this scheme, message are forward secret, but not entirely asynchronous. At some point, both the sender and recipient must have their enigmaboxes online at the same time. + +<a name="flowingmail"></a>FlowingMail +----------------------------------------------------------- + +[flowingmail.com](http://flowingmail.com) + +P2P secure, encrypted email system. + +<a name="goldbug"></a>Goldbug +----------------------------------------------------------- + +[goldbug.sf.net](http://goldbug.sf.net) + +* Written in: C++, Qt +* License: BSD + +<a name="pond"></a>Pond +----------------------------------------------------------- + +[pond.imperialviolet.org](https://pond.imperialviolet.org/) + +Pond is an email-like messaging application with several unique architectural and cryptographic features that make it stand out in the field. + +**Message Encryption**: Pond uses [Axolotl](https://github.com/trevp/axolotl/wiki) for asynchronous forward secret messages where the key is frequently ratcheted (akin to OTR, but more robust). + +**Routing**: Pond uses a unique architecture where every user relies on a service provider for receiving messages, but sent messages are delivered directly to the recipient's server (over Tor). This allows for strong metadata protection, but does not suffer from the other problems that peer-to-peer systems typically do. In order to prevent excessive Spam under this scheme, Pond uses a clever system of group signatures to allow the server to check if a sender is authorized to deliver to a particular user without leaking any information to the server. + +**Keys**: Pond uses Panda, a system for secure peer validation using short authentication strings. + +Pond's advantages include: + +* Very high security: forward secrecy, metadata protection, resistant to traffic analysis. +* Pond hybrid federated and peer-to-peer approach is cool and holds a lot of promise. +* Written in Go, and thus probably has many fewer security flaws than programs written in C or C++. +* Pond is written by Adam Langley, an extremely well respected crypto-engineer. + +Pond's disadvantages include: + +* Uses non-human memorial unique identifiers, although this is not a necessary element of the design. +* Requires that you set up contacts in advance before you can communicate with them (via a Short Authentication String or full public key exchange). +* Pond is still very difficult to install and use. + +Pond is an exciting experiment in how you could build a very secure post-email protocol. Although Pond currently uses non-human identifiers, Pond could be easily modified to use traditional email username@domain.org identifiers (because it relies on service providers for message reception). The requirement in Pond that both parties pre-exchange keys could also be modified to allow users to set up addresses that could receive messages from anyone, albeit at the cost of likely Spam. Currently, Pond uses Tor to anonymize message routing, but the Tor network was designed for low-latency. Pond could potentially use a more secure anonymization network that was designed for higher-latency asynchronous messages. + +Ultimately, Pond's unique design makes it a very strong candidate for incorporation into a messaging application that could automatically upgrade from email to Pond should it detect that both parties support it. + +* Written in: Go +* Source code: https://github.com/agl/pond +* License: BSD +* Platforms: anything you can compile Go on (for command line interface) or anything you can compile Go + Gtk (for GUI interface). + +<a name="related-works"></a>Related Works +=========================================================== + +There are many technologies that don't belong in this document because they either (a) are not trying to make encrypted email-like communication easier, (b) use some kind of weird proprietary escrow system, or (c) we just don't know enough about them yet.

This strategy allows for a gradual transition from existing email to secure email. In the short term, there are immediate benefits to a user's security when they adopt LEAP email. In the long term, as more service providers adopt the LEAP platform, email among these service providers gains even more protection. + +Above all else, our focus is on creating a user experience that is as easy and trouble-free as possible while still ensuring a very high level of security. + +## How it works + +When a service provider runs the LEAP platform, their users can access secure email in three steps: + +1. Download and install the Bitmask application. +2. Run the Bitmask application to log in or sign up with the service provider. +3. Configure the user's mail client to connect to the local Bitmask application. In case of the Thunderbird email client, this configuration is semi-automatic. + +The Bitmask application acts as a "proxy" between the service provider and the mail client. It handles all the encryption and data synchronization. + +## Immediate benefits of using LEAP email + +Email features include: + +* LEAP encrypted email is easy to use while still being backward compatible with the existing OpenPGP protocol for secure email. +* All incoming email is automatically encrypted before being stored, so only you can read it (including meta-data). +* Whenever possible, outgoing email is automatically encrypted so that only the recipients can read it (if a valid OpenPGP public keys can be discovered for the recipients). This encryption takes place on the user's device. +* OpenPGP public keys are [automatically discovered and validated](/nicknym), allowing you to have confidence your communication is confidential and with the correct person (without the headache of typical key signing). +* The user does not need to worry about key management. Their keys are always kept up-to-date on every device. +* The user is able to use any email client of their choice (e.g. Thunderbird, Apple Mail, Outlook). +* When disconnected from the internet, the user can still interact with a local copy of all their mail. When the internet connect is available again, all their changes will get synchronized with the server storage and to their other devices. + +General security features of the Bitmask application include: + +* All stored data is encrypted, including local data and cloud backups. This encryption always [takes place on the user's device](/soledad), so the service provider cannot read your stored data. +* Although you specify a username and password to login, your [password is never communicated to the provider](https://en.wikipedia.org/wiki/Secure_Remote_Password_protocol). +* If you download the Bitmask application from [downloads.leap.se](https://downloads.leap.se), your service provider cannot add a backdoor to compromise your security. +* The Bitmask application is always kept up to date with the latest security patches (coming soon). + +## Long term benefits when two LEAP compatible providers talk to one another + +One of the fundamental problems with email is that the meta-data routing information is exposed as cleartext. Encrypting a message with OpenPGP or S/MIME does nothing to help with this. + +The email protocol does support an optional method of securely relaying messages using TLS to encrypt the connection. This method, called StartTLS, is easily undermined by attackers and there is no good way for email providers to validate the authenticity of other servers (without relying on the problematic CA certificate authority system). + +For now, LEAP addresses these problems with two enhancements when two compatible providers are talking to one another: + +* When relaying email, server keys are discovered and validated using DNSSEC/DANE. +* For these providers, TLS with validated keys becomes required for all communication. + +This approach is effective against external network observers, but does not protect the meta-data from the service providers themselves. Also, it does not, by itself, protect against more advanced attacks involving timing and traffic analysis. + +In the long term, we plan to adopt one of several different schemes for [securely routing meta-data](routing). + +## Limitations + +* Missing features: the initial release will not support email aliases, email forwarding, or multiple accounts simultaneously. +* You cannot use LEAP email from a web browser. It requires the Bitmask application to run. +* The Bitmask application currently requires a compatible provider. We have plans in the future to semi-support commercial providers like gmail. This would provide the user with much less protection than when they use a LEAP provider, but will still greatly enhance their email security. +* Because all data is synced, if a user has one of their devices compromised, then the attacker has access to all their data. This is obvious, but worth mentioning. +* The user must keep a complete copy of their entire email storage on every device they use. In the future, we plan to support partial syncing for mobile devices. +* We do not plan to support key revocation. Instead, we plan to migrate to shorter and shorter lived keys, as practical. +* With the current implementation, a compromised or nefarious service provider can still gather incoming messages that are not encrypted and meta-data routing information. As more users and providers adopt secure email, many of these problems will go away. + +For more details, please see [known limitations](limitations). + +## Related projects + +There are numerous other projects working on the next generation of secure email.

For EIP, the client will do everything it can to troubleshoot on its own to get a stable encrypted tunnel established.

When a new client version is available, and the provider supports the API version of the new client, then the new code will be download from LEAP and verified using the keys included with the first download. Alternately, on platforms with good package management, like Debian or Redhat variants of GNU/Linux, updates to the LEAP Client will go through the normal platform specific channels. + +%p This system still leaves open the problem of how to distribute the initial client that is first installed.

We are committed to extending support to mobile devices once the desktop version is stable (although currently, Apple's terms of service for the appstore prevent GPL licensed apps, so until this changes we can't distribute on iOS). The mobile version of the LEAP Client will lag behind the desktop version, but our goal is to provide eventual feature parity. + +%p Recent advancements in Javascript and HTML have begun to blur the distinction between client applications that a user installs and client applications that run in a web browser environment. Although there are numerous projects actively working on client-encrypted communication that runs inside the browser, such in-browser efforts are currently crippled by a lack of standardized and trusted cryptographic primitives inside the browser and are so vulnerable to a number of common attacks.

There is no right answer for every situation. + + %p + %b No recovery: + In some situations, it makes the most sense to simply do without the ability to recover lost secrets. + + %p + %b Recovery document: + The LEAP client will give the user the option to export a text file with a complete copy of their private keys and authorization information, either password protected or not. This "recovery document" can be printed or saved electronically as the user sees fit. If the user needs to recover their data, they can load this recover document into any LEAP client. The user can also type the recovery document in manually, although it will be long and very painful to copy manually. + + %p + %b Cloud recovery: + The user is presented with a small ten by ten grid of digits (with QR code) that can be printed. To recover, the user types in these 100 digits into any LEAP client (or scans the QR code using a mobile device). This method is like manual recovery, but it is much easier to type in manually. To achieve this, the full recovery document is encrypted and then stored on the server. The user is then presented with a small code that serves as an encoded index and passphrase to retrieve the full recovery document. This method is desirable when the user does not want to be responsible for storing an electronic copy of the full recovery document. It will also serve as an easy way to set up the LEAP client on a mobile device. The disadvantage of this method is that there is potential for attack on the cloud-stored recovery document. + + %p + %b Email recovery: + The novice user should have the option to recover their secret by a simple email verification. This is less horrible than it sounds. It will work like this: when the user first installs the client, they are given the option to entrust one or more email addresses with the ability to unlock their recovery document. Additionally, they must decide how many of these email addresses must confirm the secret recovery in order for it to succeed. The LEAP client then registers these emails with a third party secret escrow service in such a way that no single party has access to the full secret (unless there is just one email). When the user triggers the reset process, the LEAP client contacts the escrow service and gives it a token to request the release of the recovery document. Once the email accounts have replied to the escrow service with confirmation of assent to the secret recovery, the LEAP client can retrieve the lost secret from the escrow service. This is a complicated process, but from the user's perspective they just hit a "recover" button and then wait for people to reply to the confirmation emails. This is a potential long term enhancement. diff --git a/pages/services/technology/critiques/en.haml b/pages/services/technology/critiques/en.haml new file mode 100644 index 0000000..06fccdd --- /dev/null +++ b/pages/services/technology/critiques/en.haml @@ -0,0 +1,57 @@ +%h1.first Anticipated Critiques + +:textile + h2.

It will not be easy, but we think it is possible. + + h2. Isn't LEAP just like FreedomBox? + + LEAP and FreedomBox share a similar goal of ensuring that everyone has the right to communicate securely and without censorship. However, the projects use different strategies for achieving this goal. + + * *FreedomBox:* Empower every user to control the hardware on which all their data is stored. Users become their own service providers, running their own hardware. + * *LEAP:* Allow service providers to deploy a cloud-based infrastructure that can scale and is easily maintained. In addition to the performance and usability found in traditional cloud services, LEAP services are also designed to bring a very high level of security to everyday users. + + FreedomBox is an important project. It faces, however, some significant hurdles. Most users demand high availability, but current technology does not allow for hardware or software that is self healing. If it did, sysadmins would be out of work. Things go wrong all the time. Take, for example, email: it is very common for an email server to get spam-bombed, or added to a blacklist, or any number of other problems that require manual intervention by a system administrator to fix. Also, most ISPs block the port needed for email rely. + + In the long run, FreedomBox has a lot of potential. But for the foreseeable future, we think it is important to also pursue the LEAP strategy. + + h2. We should not encourage users to store any data in the cloud, encrypted or not + + Even the best encryption is no guarantee of confidentiality; data in the cloud always has the potential to be decrypted by a determined attacker. + + The entire issue boils down to a matter of degree. Although there is no necessary trade off between security and convenience, you can usually achieve a higher level of security in any system by sacrificing some convenience. But what level of protection and convenience is appropriate for a particular user? + + There are very few people for whom client-encrypted data stored in the cloud will be the weakest link in the confidentiality of their communication and stored data. Most likely, there will be many aspects of their communication that are much more attractive targets to a determined adversary. + + If a person has a threat model that includes an adversary with the resources to both acquire the user's cloud data and to decrypt it, then there is little that LEAP or any other third party can do for them. They will need to become highly proficient at managing and protecting all their own data. + + There are many tools and projects out there to help a user do this. LEAP is designed for a different audience, one not adequately addressed by existing technology: people who want high security but don't have the capacity to become highly skilled in self-managing their encryption. There is room--and need--for both approaches, and it is likely that the amount of people who want high security but do not have the time or skills to adequately self-manage their own environment is already large and increasingly rapidly. + + h2. If you make your system architecture public, then you have given adversaries a blueprint to attack you + + This is, of course, similar to the arguments about the security of FLOSS. Openness can indeed lead to attacks, but more eyes leads to better security. + + In the case of an entire service provider infrastructure, however, it could be argued that things are different. We are not talking about a single piece of software, but the whole integration across many servers and services. A related critique is the potential problem of monoculture: if LEAP is successful, then a high percentage of the secure service providers will be using systems with the same vulnerabilities. + + Monoculture and openness are both interesting issues that could pose problems for the future. We can only be diligent in assessing LEAP once it is deployed by a variety of organizations. With enough flexibility in configuration, it may be that each LEAP deployment is sufficiently distinct from the others to mitigate these concerns. + + h2. Users will not be willing to download a custom client + + This will indeed be the case for a large number of potential users. Because meaningful levels of security cannot be achieved using current technology without a custom client, our hope is that a critical mass of users can be induced to use one. There are two parts to this inducement: increasing awareness as to why an extra step to ensure security is worthwhile, and decreasing the difficulty in actually taking this step. With sufficient education and an improved user experience, many users should be willing to install a custom client. + + On the other hand, rapid developments in Javascript and web browser technology have raised the possibility of running advanced client applications within the browser itself. In this case, a user would not have to install any additional software. However, in-browser crypto is still an area of active research but is currently not safe for deployment, with some areas still to be worked out (like sufficient entropy). LEAP does not depend upon the presence of cryptography in the browser, but would benefit from this should it become viable. The lead W3C employee who began the standardization of Javascript Cryptography is on the board of LEAP, and he will liaise tightly with LEAP as the work matures. + + h2. Users who need security often don't have their own device or access to the internet + + This is absolutely true. The digital divide is alive and well, and LEAP does nothing to bridge the gap between the technological haves and have-nots. However, in the long run, IP-based communication--dependent upon advanced devices such as smart phones--is likely to replace most other forms of communication. The cost of such IP-based communication devices and their connectivity is declining rapidly. It behooves us to lay the groundwork now for a secure IP-based communication infrastructure, both for the people who currently rely on the internet and for the next billion who will gain access to the internet in the near future. + + h2. Client encryption is excessive for most people + + The argument against client encryption is something like this: a secure connection is good enough, so long as the service provider is located in a country with adequate legal protection and without repressive laws. + + There are many reasons why users should be put in control of their data and should not be made to rely on a third party to safeguard it. Third parties have proven to be highly undeserving of trust--They might close shop, bow to pressure from local government, become compromised by external attacks, or accidentally leak sensitive data due to carelessness. + + Our goal is to make secure communication the default for a critical mass of users worldwide. A vital part of this strategy is cooperation with ISPs and service providers who speak the local language of their users and who are attuned to the needs of a particular context. These local service providers don't have the luxury of determining which government's jurisdiction they fall under. However, so long as encryption technology itself is not outlawed, local providers using the LEAP platform will be able to provide a high level of security for their users. + + By requiring client encryption for all services, LEAP also helps to mitigate against the myriad vulnerabilities inherent with most devices. While the LEAP client cannot defend against keyloggers, malware, or penetration of the host OS, it can ensure that all the LEAP cloud data synced by the device is stored in an encrypted format.
