RESEARCH METHODS FOR INCREASING THE SECURITY OF INFORMATION TRANSFER BASED ON TIMER SIGNALS

Abstract

Protection of information from unauthorized access is the most important task that is assigned to modern confidential communication systems. The analysis of the risks of violating the information confidentiality justifies the necessity of its protection practically on any part of the communication system's path: storage, transformation, transmission, etc. The promising direction of protecting information from unauthorized access is a comprehensive approach that provides data protection at various levels of the OSI model. The article proposes using signals with complex structure for this task. An example of such signals are timer signals, on the basis of which the possibility of integrating the processes of noise-immunity coding and structural stealth of signal construction is explored. The analysis of timer coding possibilities for providing structural stealth and correction ability is considering parameters of construction of timer signals. Quantitative and qualitative analysis of synthesized sets of timer signals was carried out for estimation of potential possibilities of increase structural secrecy with control of fidelity transmitted data. This analysis will allow choosing the optimal parameters for constructing timer signals for the task of ensuring the required accuracy of the transmitted information and the structural secrecy of signal construction. Thus, the search of effective methods of protecting information from both random interference and unauthorized access is an important task.
