## Constant-time SSSE3 AES core implementation.
## version 0.1
##
## By Mike Hamburg (Stanford University), 2009
## Public domain.

## For details see http://shiftleft.org/papers/vector_aes/ and
## http://crypto.stanford.edu/vpaes/.

######################################################################
# September 2011.
#
# Interface to OpenSSL as "almost" drop-in replacement for
# aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt
# doesn't handle partial vectors (doesn't have to if called from
# EVP only). "Drop-in" implies that this module doesn't share key
# schedule structure with the original nor does it make assumption
# about its alignment...
#
# Performance summary. aes-x86_64.pl column lists large-block CBC
# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per
# byte processed with 128-bit key, and vpaes-x86_64.pl column -
# [also large-block CBC] encrypt/decrypt.
#
#		aes-x86_64.pl		vpaes-x86_64.pl
#
# Core 2(**)	30.5/43.7/14.3		21.8/25.7(***)
# Nehalem	30.5/42.2/14.6		 9.8/11.8
# Atom		63.9/79.0/32.1		64.0/84.8(***)
#
# (*)	"Hyper-threading" in the context refers rather to cache shared
#	among multiple cores, than to specifically Intel HTT. As vast
#	majority of contemporary cores share cache, slower code path
#	is common place. In other words "with-hyper-threading-off"
#	results are presented mostly for reference purposes.
#
# (**)	"Core 2" refers to initial 65nm design, a.k.a. Conroe.
#
# (***)	Less impressive improvement on Core 2 and Atom is due to slow
#	pshufb,	yet it's respectable +40%/78% improvement on Core 2
#	(as implied, over "hyper-threading-safe" code path).
