Abstract: A new pseudo-random sequence generating method was proposed. Based on linear feedback shift register, m sequence matrix was constructed. In the m sequence matrix, each row as well as each column is a m sequence. Randomly selecting sequences from the matrix, obtained sequences are different, while extraction methods are different. Theoretical and practical analysis showed that all the sequences not only inherited the excellent pseudo-random properties of m sequence, but also could effectively resist the attack of B-M algorithm. The m sequence matrix method extends the sequence period and linear complexity, increases the key space, and improves the security of stream cipher. m sequence matrix can also be extended to any general matrix, the sequence extracted from the general matrix meets the general characteristics of pseudo-random sequence. And the sequence period is longer, the key space is larger, and the analysis of an attacker on the password is more difficult. The pseudo-random sequence generating method is simple and effective.
