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. WebFeb 28, 2024 · A stream cipher is a symmetric encryption algorithm that encrypts data bit by bit. It works by generating a stream of random bits, known as a keystream, which is combined with the plaintext bit by bit to produce the ciphertext. The keystream is generated using a secret key, which is known only to the sender and the receiver.

WebJul 24, 2024 · Stream Cipher: A stream cipher, on the other hand, encrypts one byte of data at a time. Unlike block cipher, each bit in this mode is encrypted with a different key. In terms of security, it can perform well like a block cipher if designed properly. Examples of stream ciphers include RC4, SEAL, and SNOW.
