Cryptographic stream cipher

WebThe Pike stream cipher was invented by Ross Anderson to be a "leaner and meaner" version of FISH after he broke FISH in 1994. Its name is supposed to be a humorous allusion to the pike fish . The cipher combines ideas from A5 with the lagged Fibonacci generators used in FISH. It is about 10% faster than FISH, yet believed to be much stronger. http://www.crypto-it.net/eng/symmetric/stream-ciphers.html
