# This is AESNI-CBC+SHA256 stitch implementation. The idea, as spelled
|
|
# in http://download.intel.com/design/intarch/papers/323686.pdf, is
|
|
# that since AESNI-CBC encrypt exhibit *very* low instruction-level
|
|
# parallelism, interleaving it with another algorithm would allow to
|
|
# utilize processor resources better and achieve better performance.
|
|
# SHA256 instruction sequences(*) are taken from sha512-x86_64.pl and
|
|
# AESNI code is weaved into it. As SHA256 dominates execution time,
|
|
# stitch performance does not depend on AES key length. Below are
|
|
# performance numbers in cycles per processed byte, less is better,
|
|
# for standalone AESNI-CBC encrypt, standalone SHA256, and stitched
|
|
# subroutine:
|
|
#
|
|
# AES-128/-192/-256+SHA256 this(**)gain
|
|
# Sandy Bridge 5.05/6.05/7.05+11.6 13.0 +28%/36%/43%
|
|
# Ivy Bridge 5.05/6.05/7.05+10.3 11.6 +32%/41%/50%
|

# Haswell 4.43/5.29/6.19+7.80 8.79 +39%/49%/59%

# Bulldozer 5.77/6.89/8.00+13.7 13.7 +42%/50%/58%
|
|
#
|
|
# (*) there are XOP, AVX1 and AVX2 code pathes, meaning that
|
|
# Westmere is omitted from loop, this is because gain was not
|
|
# estimated high enough to justify the effort;
|

# (**) these are EVP-free results, results obtained with 'speed
