The module is, however, dual licensed under OpenSSL and +# CRYPTOGAMS licenses depending on where you obtain it. For further +# details see http://www.openssl.org/~appro/cryptogams/. +# ==================================================================== +# +# Version 4.3. +# +# You might fail to appreciate this module performance from the first +# try. If compared to "vanilla" linux-ia32-icc target, i.e. considered +# to be *the* best Intel C compiler without -KPIC, performance appears +# to be virtually identical... But try to re-configure with shared +# library support... Aha! Intel compiler "suddenly" lags behind by 30% +# [on P4, more on others]:-) And if compared to position-independent +# code generated by GNU C, this code performs *more* than *twice* as +# fast! Yes, all this buzz about PIC means that unlike other hand- +# coded implementations, this one was explicitly designed to be safe +# to use even in shared library context... This also means that this +# code isn't necessarily absolutely fastest "ever," because in order +# to achieve position independence an extra register has to be +# off-loaded to stack, which affects the benchmark result. +# +# Special note about instruction choice. Do you recall RC4_INT code +# performing poorly on P4? It might be the time to figure out why. +# RC4_INT code implies effective address calculations in base+offset*4 +# form. Trouble is that it seems that offset scaling turned to be +# critical path... At least eliminating scaling resulted in 2.8x RC4 +# performance improvement [as you might recall]. As AES code is hungry +# for scaling too, I [try to] avoid the latter by favoring off-by-2 +# shifts and masking the result with 0xFF<<2 instead of "boring" 0xFF. +# +# As was shown by Dean Gaudet <dean@arctic.org>, the above note turned +# void. Performance improvement with off-by-2 shifts was observed on +# intermediate implementation, which was spilling yet another register +# to stack... Final offset*4 code below runs just a tad faster on P4, +# but exhibits up to 10% improvement on other cores. +# +# Second version is "monolithic" replacement for aes_core.c, which in +# addition to AES_[de|en]crypt implements AES_set_[de|en]cryption_key. +# This made it possible to implement little-endian variant of the +# algorithm without modifying the base C code. Motivating factor for +# the undertaken effort was that it appeared that in tight IA-32 +# register window little-endian flavor could achieve slightly higher +# Instruction Level Parallelism, and it indeed resulted in up to 15% +# better performance on most recent µ-archs... +# +# Third version adds AES_cbc_encrypt implementation, which resulted in +# up to 40% performance imrovement of CBC benchmark results. 40% was +# observed on P4 core, where "overall" imrovement coefficient, i.e. if +# compared to PIC generated by GCC and in CBC mode, was observed to be +# as large as 4x:-) CBC performance is virtually identical to ECB now +# and on some platforms even better, e.g. 17.6 "small" cycles/byte on +# Opteron, because certain function prologues and epilogues are +# effectively taken out of the loop... +# +# Version 3.2 implements compressed tables and prefetch of these tables +# in CBC[!] mode. Former means that 3/4 of table references are now +# misaligned, which unfortunately has negative impact on elder IA-32 +# implementations, Pentium suffered 30% penalty, PIII - 10%. +# +# Version 3.3 avoids L1 cache aliasing between stack frame and +# S-boxes, and 3.4 - L1 cache aliasing even between key schedule. The +# latter is achieved by copying the key schedule to controlled place in +# stack. This unfortunately has rather strong impact on small block CBC +# performance, ~2x deterioration on 16-byte block if compared to 3.3. +# +# Version 3.5 checks if there is L1 cache aliasing between user-supplied +# key schedule and S-boxes and abstains from copying the former if +# there is no. This allows end-user to consciously retain small block +# performance by aligning key schedule in specific manner. +# +# Version 3.6 compresses Td4 to 256 bytes and prefetches it in ECB. +# +# Current ECB performance numbers for 128-bit key in CPU cycles per +# processed byte [measure commonly used by AES benchmarkers] are: +# +# small footprint fully unrolled +# P4 24 22 +# AMD K8 20 19 +# PIII 25 23 +# Pentium 81 78 +# +# Version 3.7 reimplements outer rounds as "compact." Meaning that +# first and last rounds reference compact 256 bytes S-box. This means +# that first round consumes a lot more CPU cycles and that encrypt +# and decrypt performance becomes asymmetric. Encrypt performance +# drops by 10-12%, while decrypt - by 20-25%:-( 256 bytes S-box is +# aggressively pre-fetched. +# +# Version 4.0 effectively rolls back to 3.6 and instead implements +# additional set of functions, _[x86|sse]_AES_[en|de]crypt_compact, +# which use exclusively 256 byte S-box. These functions are to be +# called in modes not concealing plain text, such as ECB, or when +# we're asked to process smaller amount of data [or unconditionally +# on hyper-threading CPU]. Currently it's called unconditionally from +# AES_[en|de]crypt, which affects all modes, but CBC. CBC routine +# still needs to be modified to switch between slower and faster +# mode when appropriate... But in either case benchmark landscape +# changes dramatically and below numbers are CPU cycles per processed +# byte for 128-bit key. +# +# ECB encrypt ECB decrypt CBC large chunk +# P4 56[60] 84[100] 23 +# AMD K8 48[44] 70[79] 18 +# PIII 41[50] 61[91] 24 +# Core 2 32[38] 45[70] 18.5 +# Pentium 120 160 77 +# +# Version 4.1 switches to compact S-box even in key schedule setup. +# +# Version 4.2 prefetches compact S-box in every SSE round or in other +# words every cache-line is *guaranteed* to be accessed within ~50 +# cycles window. Why just SSE? Because it's needed on hyper-threading +# CPU! Which is also why it's prefetched with 64 byte stride. Best +# part is that it has no negative effect on performance:-) +# +# Version 4.3 implements switch between compact and non-compact block +# functions in AES_cbc_encrypt depending on how much data was asked +# to be processed in one stroke. +# +###################################################################### +# Timing attacks are classified in two classes: synchronous when +# attacker consciously initiates cryptographic operation and collects +# timing data of various character afterwards, and asynchronous when +# malicious code is executed on same CPU simultaneously with AES, +# instruments itself and performs statistical analysis of this data. +# +# As far as synchronous attacks go the root to the AES timing +# vulnerability is twofold. Firstly, of 256 S-box elements at most 160 +# are referred to in single 128-bit block operation. Well, in C +# implementation with 4 distinct tables it's actually as little as 40 +# references per 256 elements table, but anyway... Secondly, even +# though S-box elements are clustered into smaller amount of cache- +# lines, smaller than 160 and even 40, it turned out that for certain +# plain-text pattern[s] or simply put chosen plain-text and given key +# few cache-lines remain unaccessed during block operation. Now, if +# attacker can figure out this access pattern, he can deduct the key +# [or at least part of it]. The natural way to mitigate this kind of +# attacks is to minimize the amount of cache-lines in S-box and/or +# prefetch them to ensure that every one is accessed for more uniform +# timing. But note that *if* plain-text was concealed in such way that +# input to block function is distributed *uniformly*, then attack +# wouldn't apply. Now note that some encryption modes, most notably +# CBC, do mask the plain-text in this exact way [secure cipher output +# is distributed uniformly]. Yes, one still might find input that +# would reveal the information about given key, but if amount of +# candidate inputs to be tried is larger than amount of possible key +# combinations then attack becomes infeasible. This is why revised +# AES_cbc_encrypt "dares" to switch to larger S-box when larger chunk +# of data is to be processed in one stroke. The current size limit of +# 512 bytes is chosen to provide same [diminishigly low] probability +# for cache-line to remain untouched in large chunk operation with +# large S-box as for single block operation with compact S-box and +# surely needs more careful consideration... +# +# As for asynchronous attacks. There are two flavours: attacker code +# being interleaved with AES on hyper-threading CPU at *instruction* +# level, and two processes time sharing single core. As for latter. +# Two vectors. 1. Given that attacker process has higher priority, +# yield execution to process performing AES just before timer fires +# off the scheduler, immediately regain control of CPU and analyze the +# cache state. For this attack to be efficient attacker would have to +# effectively slow down the operation by several *orders* of magnitute, +# by ratio of time slice to duration of handful of AES rounds, which +# unlikely to remain unnoticed. Not to mention that this also means +# that he would spend correspondigly more time to collect enough +# statistical data to mount the attack. It's probably appropriate to +# say that if adeversary reckons that this attack is beneficial and +# risks to be noticed, you probably have larger problems having him +# mere opportunity. In other words suggested code design expects you +# to preclude/mitigate this attack by overall system security design. +# 2. Attacker manages to make his code interrupt driven. In order for +# this kind of attack to be feasible, interrupt rate has to be high +# enough, again comparable to duration of handful of AES rounds. But +# is there interrupt source of such rate? Hardly, not even 1Gbps NIC +# generates interrupts at such raging rate... +# +# And now back to the former, hyper-threading CPU or more specifically +# Intel P4. Recall that asynchronous attack implies that malicious +# code instruments itself. And naturally instrumentation granularity +# has be noticeably lower than duration of codepath accessing S-box. +# Given that all cache-lines are accessed during that time that is. +# Current implementation accesses *all* cache-lines within ~50 cycles +# window, which is actually *less* than RDTSC latency on Intel P4! + +$0 =~ m/(.*[\/\\])[^\/\\]+$/; $dir=$1; +push(@INC,"${dir}","${dir}../../perlasm"); +require "x86asm.pl"; + +&asm_init($ARGV[0],"aes-586.pl",$x86only = $ARGV[$#ARGV] eq "386"); +&static_label("AES_Te"); +&static_label("AES_Td"); + +$s0="eax"; +$s1="ebx"; +$s2="ecx"; +$s3="edx"; +$key="edi"; +$acc="esi"; +$tbl="ebp"; + +# stack frame layout in _[x86|sse]_AES_* routines, frame is allocated +# by caller +$__ra=&DWP(0,"esp"); # return address +$__s0=&DWP(4,"esp"); # s0 backing store +$__s1=&DWP(8,"esp"); # s1 backing store +$__s2=&DWP(12,"esp"); # s2 backing store +$__s3=&DWP(16,"esp"); # s3 backing store +$__key=&DWP(20,"esp"); # pointer to key schedule +$__end=&DWP(24,"esp"); # pointer to end of key schedule +$__tbl=&DWP(28,"esp"); # %ebp backing store + +# stack frame layout in AES_[en|crypt] routines, which differs from +# above by 4 and overlaps by %ebp backing store +$_tbl=&DWP(24,"esp"); +$_esp=&DWP(28,"esp"); + +sub _data_word() { my $i; while(defined($i=shift)) { &data_word($i,$i); } } + +$speed_limit=512; # chunks smaller than $speed_limit are + # processed with compact routine in CBC mode +$small_footprint=1; # $small_footprint=1 code is ~5% slower [on + # recent µ-archs], but ~5 times smaller! + # I favor compact code to minimize cache + # contention and in hope to "collect" 5% back + # in real-life applications... + +$vertical_spin=0; # shift "verticaly" defaults to 0, because of + # its proof-of-concept status... +# Note that there is no decvert(), as well as last encryption round is +# performed with "horizontal" shifts.

Keep in mind that z-CPUs are +# *strictly* in-order execution and issued instruction [in this case +# load value from memory is critical] has to complete before execution +# flow proceeds. S-boxes are compressed to 2KB[+256B]. +# +# As for hardware acceleration support. It's basically a "teaser," as +# it can and should be improved in several ways. Most notably support +# for CBC is not utilized, nor multiple blocks are ever processed. +# Then software key schedule can be postponed till hardware support +# detection... Performance improvement over assembler is reportedly +# ~2.5x, but can reach >8x [naturally on larger chunks] if proper +# support is implemented. + +# May 2007. +# +# Implement AES_set_[en|de]crypt_key. Key schedule setup is avoided +# for 128-bit keys, if hardware support is detected. + +# Januray 2009. +# +# Add support for hardware AES192/256 and reschedule instructions to +# minimize/avoid Address Generation Interlock hazard and to favour +# dual-issue z10 pipeline. This gave ~25% improvement on z10 and +# almost 50% on z9. The gain is smaller on z10, because being dual- +# issue z10 makes it improssible to eliminate the interlock condition: +# critial path is not long enough. Yet it spends ~24 cycles per byte +# processed with 128-bit key. +# +# Unlike previous version hardware support detection takes place only +# at the moment of key schedule setup, which is denoted in key->rounds. +# This is done, because deferred key setup can't be made MT-safe, not +# for key lengthes longer than 128 bits. +# +# Add AES_cbc_encrypt, which gives incredible performance improvement, +# it was measured to be ~6.6x.
