WebA stream cipher is a symmetric cipher which operates with a time-varying transformation on individual plaintext digits. By contrast, block ciphers operate with a fixed transformation on large blocks of plaintext digits. More precisely, in a stream cipher, a sequence of plaintext digits, ${m}_{0}{m}_{1}\ldots $, is encrypted into a sequence of ciphertext digits … WebSecure message transmission is of extreme importance intodays information-based society. Stream encryption is apractically important means to this end.
