Abstract

Perspective directions of using information technologies based on dynamic chaos for the transmission, processing, storage and protection of information are considered. On the basis of nonlinear systems with chaotic dynamics, finite-dimensional generating mathematical algorithms have been developed for the synthesis of chaotic encoding signals with increased structural complexity. The analysis of structural and fractal complexity of pseudo-random integer and binary sequences has been carried out. It is shown that complex coding signals of this type have a high information capacity and, in terms of statistical, correlation, and fractal properties, practically coincide with the parameters of random sequences and can be effectively used in various multi-user radio engineering systems where high noise immunity, protection against unauthorized access, and cryptographic strength are required.
