Abstract

CryptMT version 3 (CryptMT3) is a stream cipher obtained by combining a large LFSR and a nonlinear filter with memory using integer multiplication. Its period is proved to be no less than 219937驴 1, and the 8-bit output sequence is at least 1241-dimensionally equidistributed. It is one of the fastest stream ciphers on a CPU with SIMD operations, such as Intel Core 2 Duo.
