reference implementation, it does not interface to OpenSSL yet.

# ====================================================================
|

# 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/.

# Bit-sliced AES for ARM NEON
|
||||
#
|
||||
# February 2012.
|
||||
#
|
||||
# This implementation is direct adaptation of bsaes-x86_64 module for
|
||||
# ARM NEON. Except that this module is endian-neutral [in sense that
|
||||
# it can be compiled for either endianness] by courtesy of vld1.8's
|
||||
# neutrality. Initial version doesn't implement interface to OpenSSL,
|
||||
# only low-level primitives and unsupported entry points, just enough
|
||||
# to collect performance results, which for Cortex-A8 core are:
|
||||
#
|
||||
# encrypt 20.9 cycles per byte processed with 128-bit key
|
||||
# decrypt 25.6 cycles per byte processed with 128-bit key
|
||||
# key conv. 900 cycles per 128-bit key/0.34 of 8x block
|
||||
#
|
||||
# When comparing to x86_64 results keep in mind that NEON unit is
|
||||
# [mostly] single-issue and thus can't benefit from parallelism. And
|
||||
# when comparing to aes-armv4 results keep in mind key schedule
|
||||
# conversion overhead (see bsaes-x86_64.pl for details)...
