The results of evaluation of the potential structural secrecy of multi-frequency signals of wireless broadband communication systems are given, and new data on structural secrecy of OFDM signals are obtained. The structure of the communication system with protection against information interception, when using OFDM signals, is offered; this structure implements algorithms of pseudorandom changing time and frequency signal parameters based on the total system key.
