SSE2 Serpent on Atom N270: twice as fast as AES-128
On the Intel Atom N270 processor, OpenSSL 0.9.8g's implementation
of AES-128 runs at 25 MiB per second (CBC mode, using openssl
speed). In contrast, the Serpent implementation using SSE2
I described last
month runs at over 60 MiB per second in ECB mode (2.4x faster) and
48 MiB per second in CTR mode (1.9x faster).
