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 52[54] 83[95] 23 -# AMD K8 46[41] 66[70] 18 -# PIII 41[50] 60[77] 24 -# Core 2 31[36] 45[64] 18.5 -# Atom 76[100] 96[138] 60 -# Pentium 115 150 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.

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.

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 keys longer than 128 bits. -# -# Add AES_cbc_encrypt, which gives incredible performance improvement, -# it was measured to be ~6.6x. It's less than previously mentioned 8x, -# because software implementation was optimized. - -# May 2010. -# -# Add AES_ctr32_encrypt. If hardware-assisted, it provides up to 4.3x -# performance improvement over "generic" counter mode routine relying -# on single-block, also hardware-assisted, AES_encrypt. "Up to" refers -# to the fact that exact throughput value depends on current stack -# frame alignment within 4KB page. In worst case you get ~75% of the -# maximum, but *on average* it would be as much as ~98%.

For processors that -# can schedule aes[enc|dec] every cycle optimal interleave factor -# equals to corresponding instructions latency. 8x is optimal for -# * Bridge, but it's unfeasible to accommodate such implementation -# in XMM registers addreassable in 32-bit mode and therefore maximum -# of 6x is used instead... - -sub aesni_generate2 -{ my $p=shift; - - &function_begin_B("_aesni_${p}rypt2"); - &$movekey ($rndkey0,&QWP(0,$key)); - &shl ($rounds,4); - &$movekey ($rndkey1,&QWP(16,$key)); - &xorps ($inout0,$rndkey0); - &pxor ($inout1,$rndkey0); - &$movekey ($rndkey0,&QWP(32,$key)); - &lea ($key,&DWP(32,$key,$rounds)); - &neg ($rounds); - &add ($rounds,16); - - &set_label("${p}2_loop"); - eval"&aes${p} ($inout0,$rndkey1)"; - eval"&aes${p} ($inout1,$rndkey1)"; - &$movekey ($rndkey1,&QWP(0,$key,$rounds)); - &add ($rounds,32); - eval"&aes${p} ($inout0,$rndkey0)"; - eval"&aes${p} ($inout1,$rndkey0)"; - &$movekey ($rndkey0,&QWP(-16,$key,$rounds)); - &jnz (&label("${p}2_loop")); - eval"&aes${p} ($inout0,$rndkey1)"; - eval"&aes${p} ($inout1,$rndkey1)"; - eval"&aes${p}last ($inout0,$rndkey0)"; - eval"&aes${p}last ($inout1,$rndkey0)"; - &ret(); - &function_end_B("_aesni_${p}rypt2"); -} - -sub aesni_generate3 -{ my $p=shift; - - &function_begin_B("_aesni_${p}rypt3"); - &$movekey ($rndkey0,&QWP(0,$key)); - &shl ($rounds,4); - &$movekey ($rndkey1,&QWP(16,$key)); - &xorps ($inout0,$rndkey0); - &pxor ($inout1,$rndkey0); - &pxor ($inout2,$rndkey0); - &$movekey ($rndkey0,&QWP(32,$key)); - &lea ($key,&DWP(32,$key,$rounds)); - &neg ($rounds); - &add ($rounds,16); - - &set_label("${p}3_loop"); - eval"&aes${p} ($inout0,$rndkey1)"; - eval"&aes${p} ($inout1,$rndkey1)"; - eval"&aes${p} ($inout2,$rndkey1)"; - &$movekey ($rndkey1,&QWP(0,$key,$rounds)); - &add ($rounds,32); - eval"&aes${p} ($inout0,$rndkey0)"; - eval"&aes${p} ($inout1,$rndkey0)"; - eval"&aes${p} ($inout2,$rndkey0)"; - &$movekey ($rndkey0,&QWP(-16,$key,$rounds)); - &jnz (&label("${p}3_loop")); - eval"&aes${p} ($inout0,$rndkey1)"; - eval"&aes${p} ($inout1,$rndkey1)"; - eval"&aes${p} ($inout2,$rndkey1)"; - eval"&aes${p}last ($inout0,$rndkey0)"; - eval"&aes${p}last ($inout1,$rndkey0)"; - eval"&aes${p}last ($inout2,$rndkey0)"; - &ret(); - &function_end_B("_aesni_${p}rypt3"); -} - -# 4x interleave is implemented to improve small block performance, -# most notably [and naturally] 4 block by ~30%.

This -# module also provides better performance for block sizes smaller than -# 128 bytes in points *not* represented in the above table. -# -# Looking at the results for 8-KB buffer. -# -# CFB and OFB results are far from the limit, because implementation -# uses "generic" CRYPTO_[c|o]fb128_encrypt interfaces relying on -# single-block aesni_encrypt, which is not the most optimal way to go. -# CBC encrypt result is unexpectedly high and there is no documented -# explanation for it. Seemingly there is a small penalty for feeding -# the result back to AES unit the way it's done in CBC mode. There is -# nothing one can do and the result appears optimal. CCM result is -# identical to CBC, because CBC-MAC is essentially CBC encrypt without -# saving output. CCM CTR "stays invisible," because it's neatly -# interleaved wih CBC-MAC. This provides ~30% improvement over -# "straghtforward" CCM implementation with CTR and CBC-MAC performed -# disjointly. Parallelizable modes practically achieve the theoretical -# limit. -# -# Looking at how results vary with buffer size. -# -# Curves are practically saturated at 1-KB buffer size. In most cases -# "256-byte" performance is >95%, and "64-byte" is ~90% of "8-KB" one. -# CTR curve doesn't follow this pattern and is "slowest" changing one -# with "256-byte" result being 87% of "8-KB." This is because overhead -# in CTR mode is most computationally intensive. Small-block CCM -# decrypt is slower than encrypt, because first CTR and last CBC-MAC -# iterations can't be interleaved. -# -# Results for 192- and 256-bit keys. -# -# EVP-free results were observed to scale perfectly with number of -# rounds for larger block sizes, i.e. 192-bit result being 10/12 times -# lower and 256-bit one - 10/14. Well, in CBC encrypt case differences -# are a tad smaller, because the above mentioned penalty biases all -# results by same constant value. In similar way function call -# overhead affects small-block performance, as well as OFB and CFB -# results. Differences are not large, most common coefficients are -# 10/11.7 and 10/13.4 (as opposite to 10/12.0 and 10/14.0), but one -# observe even 10/11.2 and 10/12.4 (CTR, OFB, CFB)... - -# January 2011 -# -# While Westmere processor features 6 cycles latency for aes[enc|dec] -# instructions, which can be scheduled every second cycle, Sandy -# Bridge spends 8 cycles per instruction, but it can schedule them -# every cycle. This means that code targeting Westmere would perform -# suboptimally on Sandy Bridge. Therefore this update. -# -# In addition, non-parallelizable CBC encrypt (as well as CCM) is -# optimized. Relative improvement might appear modest, 8% on Westmere, -# but in absolute terms it's 3.77 cycles per byte encrypted with -# 128-bit key on Westmere, and 5.07 - on Sandy Bridge. These numbers -# should be compared to asymptotic limits of 3.75 for Westmere and -# 5.00 for Sandy Bridge. Actually, the fact that they get this close -# to asymptotic limits is quite amazing. Indeed, the limit is -# calculated as latency times number of rounds, 10 for 128-bit key, -# and divided by 16, the number of bytes in block, or in other words -# it accounts *solely* for aesenc instructions. But there are extra -# instructions, and numbers so close to the asymptotic limits mean -# that it's as if it takes as little as *one* additional cycle to -# execute all of them. How is it possible? It is possible thanks to -# out-of-order execution logic, which manages to overlap post- -# processing of previous block, things like saving the output, with -# actual encryption of current block, as well as pre-processing of -# current block, things like fetching input and xor-ing it with -# 0-round element of the key schedule, with actual encryption of -# previous block. Keep this in mind... -# -# For parallelizable modes, such as ECB, CBC decrypt, CTR, higher -# performance is achieved by interleaving instructions working on -# independent blocks. In which case asymptotic limit for such modes -# can be obtained by dividing above mentioned numbers by AES -# instructions' interleave factor. Westmere can execute at most 3 -# instructions at a time, meaning that optimal interleave factor is 3, -# and that's where the "magic" number of 1.25 come from. "Optimal -# interleave factor" means that increase of interleave factor does -# not improve performance. The formula has proven to reflect reality -# pretty well on Westmere... Sandy Bridge on the other hand can -# execute up to 8 AES instructions at a time, so how does varying -# interleave factor affect the performance? Here is table for ECB -# (numbers are cycles per byte processed with 128-bit key): -# -# instruction interleave factor 3x 6x 8x -# theoretical asymptotic limit 1.67 0.83 0.625 -# measured performance for 8KB block 1.05 0.86 0.84 -# -# "as if" interleave factor 4.7x 5.8x 6.0x -# -# Further data for other parallelizable modes: -# -# CBC decrypt 1.16 0.93 0.74 -# CTR 1.14 0.91 0.74 -# -# Well, given 3x column it's probably inappropriate to call the limit -# asymptotic, if it can be surpassed, isn't it? What happens there? -# Rewind to CBC paragraph for the answer. Yes, out-of-order execution -# magic is responsible for this. Processor overlaps not only the -# additional instructions with AES ones, but even AES instuctions -# processing adjacent triplets of independent blocks. In the 6x case -# additional instructions still claim disproportionally small amount -# of additional cycles, but in 8x case number of instructions must be -# a tad too high for out-of-order logic to cope with, and AES unit -# remains underutilized... As you can see 8x interleave is hardly -# justifiable, so there no need to feel bad that 32-bit aesni-x86.pl -# utilizies 6x interleave because of limited register bank capacity. -# -# Higher interleave factors do have negative impact on Westmere -# performance. While for ECB mode it's negligible ~1.5%, other -# parallelizables perform ~5% worse, which is outweighed by ~25% -# improvement on Sandy Bridge. To balance regression on Westmere -# CTR mode was implemented with 6x aesenc interleave factor. - -# April 2011 -# -# Add aesni_xts_[en|de]crypt. Westmere spends 1.25 cycles processing -# one byte out of 8KB with 128-bit key, Sandy Bridge - 0.90.

some instruction reordering and interleaving; -# - this module doesn't implement key setup subroutine, instead it -# relies on conversion of "conventional" key schedule as returned -# by AES_set_encrypt_key (see discussion below); -# - first and last round keys are treated differently, which allowed -# to skip one shiftrows(), reduce bit-sliced key schedule and -# speed-up conversion by 22%; -# - support for 192- and 256-bit keys was added; -# -# Resulting performance in CPU cycles spent to encrypt one byte out -# of 4096-byte buffer with 128-bit key is: -# -# Emilia's this(*) difference -# -# Core 2 9.30 8.69 +7% -# Nehalem(**) 7.63 6.88 +11% -# Atom 17.1 16.4 +4% -# Silvermont - 12.9 -# -# (*) Comparison is not completely fair, because "this" is ECB, -# i.e. no extra processing such as counter values calculation -# and xor-ing input as in Emilia's CTR implementation is -# performed. However, the CTR calculations stand for not more -# than 1% of total time, so comparison is *rather* fair. -# -# (**) Results were collected on Westmere, which is considered to -# be equivalent to Nehalem for this code. -# -# As for key schedule conversion subroutine.
