RÉSUMÉ

The problem of the information-theoretical methods application to estimation of communication systems security on the channel and physical level of the model of the OSI communications is presented. The methodology is offered for estimating the level of security of data transmission systems (DTS) using the notion of vulnerability in the energy gap from interception (security gap). The comparative estimates of security of the DTS with different methods of modulation, coding and scrambling signal in the main channel of communication are obtained.
