Prokopovych-Tkachenko D. Wireless telecommunication networks safety improvement method and means based on pseudorandom access authorization keys forming.

The object of study. The process of authorization of access to improve security of wireless TSN. The subject of the study. Methods and means of improving the security of wireless TSN based on the formation of pseudo-random KAA. The aim of the thesis is to improve the security of wireless TSN based on the formation of pseudo-random KAA. Metody study. When doing dissertation research methods used theories broadcast data authentication theory, mathematical modeling and simulation, probability theory and mathematical statistics, elements of the theory of finite fields and number theory. Scientific novelty determined theoretical generalization and a new solution of important scientific and technical problems, which is to develop a method of improving the safety of wireless TSN based on the formation of pseudo-random KAA. We obtain the following research results: It is the first time when the mathematical model of authorization and authentication, wireless access, which accounted conflict and periodic properties of the molded KAA for safety evaluation of wireless TSN. The method of wireless access authorization and authentication is improved. If differs from the other known methods by using preudorandom series of maximum period, as it allows increasing wireless telecommunication systems and networks safety due to necessary collision properties of autorization formed keys support. Pseudorandom consecutive orders formation method is smproved. It provides maximum period of formed consecutive orders of pseudorandom authorization keys for wireless telecommunication systems and networks due to additional intel of recurrent development over the transient conditions of generator.
