Re: Implementing byte stream cipher

Although Tom may have a different opinion to this end :)
I suggest Salsa20 Stream Cipher by DJB.

Its there on ecrypt.eu.org/estream

Salsa20 uses on XOR, ADD and Rotate. Again Salsa requires no lookup
tables, is amazingly fast and trivial to code :)
Imlemented the same on a P89C51 (8051 Derivative) as a Pre-Final Year
Hobby Ckt (Its so easy), if you need the schematics or anything, do let
me know.
TEA code is available for the 8051 on many hobby sites.
