4## Constant-time SSSE3 AES core implementation.
5## version 0.1
6##
7## By Mike Hamburg (Stanford University), 2009
8## Public domain.

14# September 2011.
15#
16# Interface to OpenSSL as "almost" drop-in replacement for
17# aes-x86_64.pl. "Almost" refers to the fact that AES_cbc_encrypt
18# doesn't handle partial vectors (doesn't have to if called from
19# EVP only). "Drop-in" implies that this module doesn't share key
20# schedule structure with the original nor does it make assumption
21# about its alignment...
22#
23# Performance summary. aes-x86_64.pl column lists large-block CBC
24# encrypt/decrypt/with-hyper-threading-off(*) results in cycles per
25# byte processed with 128-bit key, and vpaes-x86_64.pl column -
26# [also large-block CBC] encrypt/decrypt.
27#
28# aes-x86_64.pl vpaes-x86_64.pl

30# Core 2(**) 30.5/43.7/14.3 21.8/25.7(***)
31# Nehalem 30.5/42.2/14.6 9.8/11.8
32# Atom 63.9/79.0/32.1 64.0/84.8(***)
33#
34# (*) "Hyper-threading" in the context refers rather to cache shared
35# among multiple cores, than to specifically Intel HTT. As vast
36# majority of contemporary cores share cache, slower code path
37# is common place. In other words "with-hyper-threading-off"
38# results are presented mostly for reference purposes.
39#
40# (**) "Core 2" refers to initial 65nm design, a.k.a. Conroe.
41#
42# (***) Less impressive improvement on Core 2 and Atom is due to slow
43# pshufb, yet it's respectable +40%/78% improvement on Core 2
44# (as implied, over "hyper-threading-safe" code path).
