Abstract: Multi-component generators of pseudorandom multi-dimensional and two-dimensional signals based on the selection of the set of non-linear functions, the type of the relationship between the non-linear functions, the order of using the initial key parameters and the type of processing of the generated pseudorandom signal and allowing to improve the statistical and cryptographic properties of ones are developed. The results of the simulation of multi-component ring and parallel random generators, twocomponent generator with random permutations, the two-dimensional generator of the vertical-horizontal permutations matrix and multi-component moire mask generator are presented.

Keywords: one- and multi-component pseudorandom generators, chaotic function, moire mask, initial key parameters, stream encryption, entropy.
