【 摘 要 】

Shannon is a synchronous stream cipher with message authentication functionality, designed according to the ECrypt NoE call for stream cipher primitives, profile 1A (but well after the call). Shannon is named in memory of Claude E. Shannon[20] of Bell Labs and MIT, founder of Information Theory. Shannon is anentirely new design, influenced by members ofthe SOBERfamily ofstream ciphers[11][13][19], Helix/Phelix[7], Trivium[4], Scream[10], and SHA-256[8]. It consists of a single 2-bit wide, 16-element nonlinear feedback shift register and an extra word, which is supplemented for message authentication with 32 parallel CRC-16 registers.
