The article presents the results of the influence of the statistical characteristics of the pseudorandom sequence generator on improving the energy efficiency and information security of the communication system with OFDM. The influence of the modulation depth of a discrete-nonlinear Lorentz system subject to quasi-resonant influences on the autocorrelation function and on the probability of passing the universal set of computer security tests FIPS-140-2 is considered. The paper describes the results of the influence of the modulation depth on the peak factor of the signals of the considered communication system with OFDM and the entropy of the transmitted information. The results presented in the work can be used in the design of the modern communication systems with OFDM in order to increase the energy efficiency and information security of the transmitted information.
