Add an implementation of AES-128 using SSSE3 instructions. It runs in
constant time and on a Nehalem is significantly faster than the table
based version. This implementation technique was invented by Mike
Hamburg and described in a paper in CHES 2009 "Accelerating AES with
Vector Permute Instructions". This code is basically a translation of
his public domain x86-64 assembly code into intrinsics.
Todo: Adding support for AES-192 and AES-256; this just requires
implementing the key schedules.
Currently only tested on an i7 with GCC (32 and 64 bit code);
testing/optimization on 32-bit processors with SSSE3 like the Atom,
and with Visual C++ and other compilers, are also todos.
