# Version 1.1
#
# The major reason for undertaken effort was to mitigate the hazard of
# cache-timing attack. This is [currently and initially!] addressed in
# two ways. 1. S-boxes are compressed from 5KB to 2KB+256B size each.
# 2. References to them are scheduled for L2 cache latency, meaning
# that the tables don't have to reside in L1 cache. Once again, this
# is an initial draft and one should expect more countermeasures to
# be implemented...
#
# Version 1.1 prefetches T[ed]4 in order to mitigate attack on last
# round.
#
# Even though performance was not the primary goal [on the contrary,
# extra shifts "induced" by compressed S-box and longer loop epilogue
# "induced" by scheduling for L2 have negative effect on performance],
# the code turned out to run in ~23 cycles per processed byte en-/
# decrypted with 128-bit key. This is pretty good result for code
# with mentioned qualities and UltraSPARC core. Compared to Sun C
# generated code my encrypt procedure runs just few percents faster,
# while decrypt one - whole 50% faster [yes, Sun C failed to generate
# optimal decrypt procedure]. Compared to GNU C generated code both
# procedures are more than 60% faster:-)
