The biggest one is avoiding a bunch of bit reversals by keeping numbers in bit-reversed form for as long as we can. Also reduced the hashing rounds: just 2 rounds seems to be enough for a reasonable amount of statistical independence on both the scrambling and shuffling. I tested both independently, keeping the other with no scrambling/shuffling respectively. This makes sense because in normal contexts 3 is enough, but in this case both act as input to yet another hash which is effectively doing more rounds. |
