Pseudo-random sequences identification by probability distribution moments

The paper discusses the method for determining the deterministic nature of a pseudo-random process, formed by a nonlinear mapping 0,1 to 0,1. The method is based on comparing two-dimensional mixed moments of distributions of values generated by this mapping. The possibility of approximation for the mapping that generates pseudo-random process based on aggregation of two-dimensional mixed distribution moment is considered. (In Russian). (in Russian).
