- Stream ciphers (additive)
This reminds me, when people talk about linearity with regard to a function, for example CRCs, exactly what sense of the word do they mean? I can understand f(x) = ax + b being linear, but how exactly does XOR get involved, and are there +-linear functions and xor-linear functions? Are they disjoint? etc. -- "Curiousity killed the cat, but for a while I was a suspect" -- Steven Wright Security Guru for Hire http://www.lightconsulting.com/~travis/ -><- GPG fingerprint: 9D3F 395A DAC5 5CCC 9066 151D 0A6B 4098 0C55 1484 --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to [EMAIL PROTECTED]
