# ====================================================================
|
||||
# [Re]written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
|
||||
# project. 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/.
|
||||
# ====================================================================
|
||||
|
||||
# At some point it became apparent that the original SSLeay RC4
|
||||
# assembler implementation performs suboptimally on latest IA-32
|
||||
# microarchitectures. After re-tuning performance has changed as
|
||||
# following:
|
||||
#
|
||||
# Pentium -10%
|
||||
# Pentium III +12%
|
||||
# AMD +50%(*)
|
||||
# P4 +250%(**)
|
||||
#
|
||||
# (*) This number is actually a trade-off:-) It's possible to
|
||||
# achieve +72%, but at the cost of -48% off PIII performance.
|
||||
# In other words code performing further 13% faster on AMD
|
||||
# would perform almost 2 times slower on Intel PIII...
|
||||
# For reference! This code delivers ~80% of rc4-amd64.pl
|
||||
# performance on the same Opteron machine.
|
||||
# (**) This number requires compressed key schedule set up by
|
||||
# RC4_set_key [see commentary below for further details].

|

# This is a little helper program which generates a software-pipelined
|
||||
# for RC4 encryption. The basic algorithm looks like this:
|
||||
#
|
||||
# for (counter = 0; counter < len; ++counter)
|
||||
# {
|
||||
# in = inp[counter];
|
||||
# SI = S[I];
|
||||
# J = (SI + J) & 0xff;
|
||||
# SJ = S[J];
|
||||
# T = (SI + SJ) & 0xff;
|
||||
# S[I] = SJ, S[J] = SI;
|
||||
# ST = S[T];
|
||||
# outp[counter] = in ^ ST;
|
||||
# I = (I + 1) & 0xff;
|
||||
# }
|
||||
#
|
||||
# Pipelining this loop isn't easy, because the stores to the S[] array
|
||||
# need to be observed in the right order. The loop generated by the
|
||||
# code below has the following pipeline diagram:
|
||||
#
|
||||
# cycle
|
||||
# | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |10 |11 |12 |13 |14 |15 |16 |17 |
|
||||
# iter
|
||||
# 1: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
|
||||
# 2: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
|
||||
# 3: xxx LDI xxx xxx xxx LDJ xxx SWP xxx LDT xxx xxx
|
||||
#
|
||||
# where:
|
||||
# LDI = load of S[I]
|
||||
# LDJ = load of S[J]
|
||||
# SWP = swap of S[I] and S[J]
|
||||
# LDT = load of S[T]
|
||||
#
|
||||
# Note that in the above diagram, the major trouble-spot is that LDI
|
||||
# of the 2nd iteration is performed BEFORE the SWP of the first
|
||||
# iteration. Fortunately, this is easy to detect (I of the 1st
|
||||
# iteration will be equal to J of the 2nd iteration) and when this
|
||||
# happens, we simply forward the proper value from the 1st iteration
|
||||
# to the 2nd one. The proper value in this case is simply the value
|
||||
# of S[I] from the first iteration (thanks to the fact that SWP
|
||||
# simply swaps the contents of S[I] and S[J]).
|
||||
#
|
||||
# Another potential trouble-spot is in cycle 7, where SWP of the 1st
|
||||
# iteration issues at the same time as the LDI of the 3rd iteration.
|
||||
# However, thanks to IA-64 execution semantics, this can be taken
|
||||
# care of simply by placing LDI later in the instruction-group than
|
||||
# SWP. IA-64 CPUs will automatically forward the value if they
|
||||
# detect that the SWP and LDI are accessing the same memory-location.
|
||||
|
||||
# The core-loop that can be pipelined then looks like this (annotated
|
||||
# with McKinley/Madison issue port & latency numbers, assuming L1
|
||||
# cache hits for the most part):

|
||||
|
||||
# There are several points worth making here:
|
||||
|
||||
# - Note that due to the bypass/forwarding-path, the first two
|
||||
# phases of the loop are strangly mingled together. In
|
||||
# particular, note that the first stage of the pipeline is
|
||||
# using the value of "J", as calculated by the second stage.
|
||||
# - Each bundle-pair will have exactly 6 instructions.
|
||||
# - Pipelined, the loop can execute in 3 cycles/iteration and
|
||||
# 4 stages. However, McKinley/Madison can issue "st1" to
|
||||
# the same bank at a rate of at most one per 4 cycles. Thus,
|
||||
# instead of storing each byte, we accumulate them in a word
|
||||
# and then write them back at once with a single "st8" (this
|
||||
# implies that the setup code needs to ensure that the output
|
||||
# buffer is properly aligned, if need be, by encoding the
|
||||
# first few bytes separately).
|
||||
# - There is no space for a "br.ctop" instruction. For this
|
||||
# reason we can't use module-loop support in IA-64 and have
|
||||
# to do a traditional, purely software-pipelined loop.
|
||||
# - We can't replace any of the remaining "add/zxt1" pairs with
|
||||
# "padd1" because the latency for that instruction is too high
|
||||
# and would push the loop to the point where more bypasses
|
||||
# would be needed, which we don't have space for.
|
||||
# - The above loop runs at around 3.26 cycles/byte, or roughly
|
||||
# 440 MByte/sec on a 1.5GHz Madison. This is well below the
|
||||
# system bus bandwidth and hence with judicious use of
|
||||
# "lfetch" this loop can run at (almost) peak speed even when
|
||||
# the input and output data reside in memory. The
|
||||
# max. latency that can be tolerated is (PREFETCH_DISTANCE *
|
||||
# L2_LINE_SIZE * 3 cyc), or about 384 cycles assuming (at
|
||||
# least) 1-ahead prefetching of 128 byte cache-lines. Note
|
||||
# that we do NOT prefetch into L1, since that would only
|
||||
# interfere with the S[] table values stored there. This is
|
||||
# acceptable because there is a 10 cycle latency between
|
||||
# load and first use of the input data.
|
||||
# - We use a branch to out-of-line bypass-code of cycle-pressure:
|
||||
# we calculate the next J, check for the need to activate the
|
||||
# bypass path, and activate the bypass path ALL IN THE SAME
|
||||
# CYCLE. If we didn't have these constraints, we could do
|
||||
# the bypass with a simple conditional move instruction.
|
||||
# Fortunately, the bypass paths get activated relatively
|
||||
# infrequently, so the extra branches don't cost all that much
|
||||
# (about 0.04 cycles/byte, measured on a 16396 byte file with
|
||||
# random input data).

# ====================================================================
|
||||
# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL
|
||||
# project. 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/.
|
||||
# ====================================================================
|
||||
#
|
||||
# 2.22x RC4 tune-up:-) It should be noted though that my hand [as in
|
||||
# "hand-coded assembler"] doesn't stand for the whole improvement
|
||||
# coefficient. It turned out that eliminating RC4_CHAR from config
|
||||
# line results in ~40% improvement (yes, even for C implementation).
|
||||
# Presumably it has everything to do with AMD cache architecture and
|
||||
# RAW or whatever penalties. Once again! The module *requires* config
|
||||
# line *without* RC4_CHAR! As for coding "secret," I bet on partial
|
||||
# register arithmetics. For example instead of 'inc %r8; and $255,%r8'
|
||||
# I simply 'inc %r8b'. Even though optimization manual discourages
|
||||
# to operate on partial registers, it turned out to be the best bet.
|
||||
# At least for AMD... How IA32E would perform remains to be seen...
|
||||
|
||||
# As was shown by Marc Bevand reordering of couple of load operations
|
||||
# results in even higher performance gain of 3.3x:-) At least on
|
||||
# Opteron... For reference, 1x in this case is RC4_CHAR C-code
|
||||
# compiled with gcc 3.3.2, which performs at ~54MBps per 1GHz clock.
|
||||
# Latter means that if you want to *estimate* what to expect from
|
||||
# *your* Opteron, then multiply 54 by 3.3 and clock frequency in GHz.
|
||||
|
||||
# Intel P4 EM64T core was found to run the AMD64 code really slow...
|
||||
# The only way to achieve comparable performance on P4 was to keep
|
||||
# RC4_CHAR. Kind of ironic, huh? As it's apparently impossible to
|
||||
# compose blended code, which would perform even within 30% marginal
|
||||
# on either AMD and Intel platforms, I implement both cases. See
|
||||
# rc4_skey.c for further details...
|
||||
|
||||
# P4 EM64T core appears to be "allergic" to 64-bit inc/dec. Replacing
|
||||
# those with add/sub results in 50% performance improvement of folded
|
||||
# loop...
|
||||
|
||||
# As was shown by Zou Nanhai loop unrolling can improve Intel EM64T
|
||||
# performance by >30% [unlike P4 32-bit case that is]. But this is
|
||||
# provided that loads are reordered even more aggressively! Both code
|
||||
# pathes, AMD64 and EM64T, reorder loads in essentially same manner
|
||||
# as my IA-64 implementation. On Opteron this resulted in modest 5%
|
||||
# improvement [I had to test it], while final Intel P4 performance
|
||||
# achieves respectful 432MBps on 2.8GHz processor now. For reference.
|
||||
# If executed on Xeon, current RC4_CHAR code-path is 2.7x faster than
|
||||
# RC4_INT code-path. While if executed on Opteron, it's only 25%
|
||||
# slower than the RC4_INT one [meaning that if CPU µ-arch detection
|
||||
# is not implemented, then this final RC4_CHAR code-path should be
|
||||
# preferred, as it provides better *all-round* performance].
|
||||
|
||||
# Intel Core2 was observed to perform poorly on both code paths:-( It
|
||||
# apparently suffers from some kind of partial register stall, which
|
||||
# occurs in 64-bit mode only [as virtually identical 32-bit loop was
|
||||
# observed to outperform 64-bit one by almost 50%]. Adding two movzb to
|
||||
# cloop1 boosts its performance by 80%! This loop appears to be optimal
|
||||
# fit for Core2 and therefore the code was modified to skip cloop8 on
|
||||
# this CPU.

|

* The original reason for implementing this(*) was the fact that
|
||||
* pre-21164a Alpha CPUs don't have byte load/store instructions
|
||||
* and e.g. a byte store has to be done with 64-bit load, shift,
|
||||
* and, or and finally 64-bit store. Peaking data and operating
|
||||
* at natural word size made it possible to reduce amount of
|
||||
* instructions as well as to perform early read-ahead without
|
||||
* suffering from RAW (read-after-write) hazard. This resulted
|
||||
* in ~40%(**) performance improvement on 21064 box with gcc.
|
||||
* But it's not only Alpha users who win here:-) Thanks to the
|
||||
* early-n-wide read-ahead this implementation also exhibits
|
||||
* >40% speed-up on SPARC and 20-30% on 64-bit MIPS (depending
|
||||
* on sizeof(RC4_INT)).
|
||||
*
|
||||
* (*) "this" means code which recognizes the case when input
|
||||
* and output pointers appear to be aligned at natural CPU
|
||||
* word boundary
|

I am shocked, shocked, I tell you, shocked, to discover
|

that the cypherpunks have illegaly and criminally revealed
|

a crucial RSA trade secret and harmed the security of

America by reverse engineering the RC4 algorithm and

publishing it to the world.

One data point:
|
||||
|
||||
I can't say anything about the internals of RC4 versus the
|
||||
algorithm that Bill Sommerfeld is rightly calling 'Alleged RC4',
|
||||
since I don't know anything about RC4's internals.
|
||||
|
||||
However, I do have a (legitimately acquired) copy of BSAFE2 and
|
||||
so I'm able to compare the output of this algorithm to the output
|
||||
of genuine RC4 as found in BSAFE. I chose a set of test vectors
|
||||
and ran them through both algorithms. The algorithms appear to
|
||||
give identical results, at least with these key/plaintext pairs.
|
||||
|
||||
I note that this is the algorithm _without_ Hal Finney's
|
||||
proposed modification
|
||||
|
||||
(see <199409130605.XAA24133@jobe.shell.portal.com>).
|
||||
|
||||
The vectors I used (together with the ciphertext they produce)
|
||||
follow at the end of this message.
