This article presents a new method to generate a class of nonlinear sequences based on φ(2n-1 ) /n different m - sequences the number stage of which is n , this can increase the complexity of the sequences . By computer analogy , we find that the new sequences has a peak in its auto-correlation and it has the properties similar to that of white noise . The new sequences is a good pseudo-random sequences and can be used as a kind of secret-key sequences.
