METHODS FOR ASSESSING THE SECURITY OF COMMUNICATION SYSTEMS FOR SPECIAL PURPOSES

Abstract

In the conditions of radio electronic conflict it is actual to create special-purpose communication systems able to provide high security of communication channel from means of radio technical reconnaissance and unauthorized access of the enemy. Increasing the protection of such systems is possible when using several levels of protection of transmitted information. Each level of protection is equipped with a certain arsenal of forming signal structure or data transformation. A system of assessing the effectiveness of information protection methods is suggested in this paper. As the main efficiency criteria, the secure indicators are chosen: noise immunity; structural and energy secrecy. The analysis of influence of methods of increasing energy and structural stealth on the noise immunity of the communication system, taking into account changes in the frequency and energy efficiency of the channel is carried out. The proposed system of assessments allows us to carry out the comparative analysis of information protection methods in the channel, taking into account the customer's requirements for noise immunity and data transmission.
