Recent MAC improvements
...e underlying hash function (e.g. SHA1) for each packet. My
tests found that this yielded at 12-16% speedup for bulk transfers to
localhost using HMAC-MD5 and arcfour256. HMAC-SHA1 should see an even
bigger improvement, because SHA1 is a more expensive hash function.
The second improvement is Peter Valchev's addition of a new MAC: Ted
Krovetz' UMAC-64[1]. This MAC uses a very different approach than the
HMACs that OpenSSH currently supports, and it comes with a nice security
proof that guarantees its resistance so long as its underlying block
cipher (AES) remains cryptologically intact. Testi...
