| # 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:-)
