The Pike
stream cipher
stream cipher is a symmetric key cipher where plaintext digits are combined with a pseudorandom cipher digit stream (keystream). In a stream cipher, each plaintext digit is encrypted one at a time with the corresponding digit of the keystream ...
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. It potentially has a huge
key length, and no attacks have been published .
