About the technical protection of information in OFDM communication channels

The article discusses some theoretical foundations of the organization of technical information protection in wireless OFDM communication channels of information and computing systems at the physical level of the OSI model. An analysis of a number of possibilities for organizing the technical protection of information in OFDM communication channels by increasing the structural secrecy of the OFDM word radio signal is presented. The possibility of organizing technical protection of information comparable to cryptographic protection is shown by introducing simple codes into the signal-code structure of displaying multiple messages on multiple radio signals.
