Phelix
1
is a high-speed stream cipher with a built-in MAC func-
tionality. It is efficient in both hardware and software. On current Pentium
CPUs, Phelix has a per-packet overhead of less than 900 clocks, plus a per-
byte cost well under 8 clocks per byte, comparing very favorably with the best
AES (encryption-only) implementations, even for small packets.
