Faure E. Methodology of information security based on factorial data coding

The thesis is devoted to the actual scientific and technical problem of creating the methodology of information security in telecommunication systems and networks based on factorial data coding with necessary ensemble, statistical, and structural properties of code sequences for building systems of information security against communication channels errors, unauthorized modifications and/or unauthorized access. It is shown that to date, the developed methods of integrating channel coding and encryption exist only for broadband telecommunication systems. However, these methods do not allow controlling data integrity. The solution of the problem of providing a complex information security provides related problems associated with the improvement of existing and development of new methods of cryptographic transformation and methods of generating and estimating sequences of random and pseudorandom numbers. The methodology of information security based on factorial data coding has been developed. It allows supporting the processes of creation of information security systems that implement the joint data protection from communication channel errors, unauthorized modifications and/or unauthorized access. Application of the methodology makes it possible to use the developed methods and models in a united research strategy in the field of integrated information security in telecommunication systems and networks and to effectively build appropriate security systems with given properties.
