[LCP]Speed of the popular encryption routines

[Vincent Penquerc'h]

Some random things picked up on the net:


with the TEACrypt 80x86 v1.0.8 i've managed to obtain a 15Mb/s of
throughput. This means that if you transfer file across the web you can
pratically crypt and decrypt file in real time! For example TEA can be
integrated within the FTP to have 128bit secure file transfers.


A DES implementation:
Throughput (MB/s) = 0.57 * f(MHz)


A fast encryption algorithm based on the SAFERK64 algorithm [11] has been
chosen because the processing time spent in the more complex DES encryption
algorithm can hide total ly the ILP performance gain [4] Even a high speed
implementation achieves only a 1.22 Mbps throughput on a SUN 4 280
