Faure E. The methods and facilities of data transferring dependability and efficiency enhancement in closed circuit television computer systems

Object of research - data transferring processes in open and covert channels of closed circuit television computer systems. Subject of research - methods and facilities of data transferring dependability and efficiency enhancement in specialized closed circuit television computer systems. The research purpose - development of methods and facilities of data transferring dependability and efficiency enhancement in specialized closed circuit television computer systems due to introduction of the additional covert channel; computer components dependability and efficiency enhancement. The dissertation research is devoted to the development of the methods and facilities of data transferring dependability and efficiency enhancement in specialized closed circuit television computer systems at the expense of secondary covert channel. In this research are developed: the graphic-sign model of specialized closed circuit television computer system with covert channel; the mathematical model of data transferring in open and covert channels which determines computer system components; the original methods and calculation devices of block code checksum generation directed to the calculation curtailment and code polynomial change procurement; the method of binary random sequence non-linear generation which uses discrete random processes; the mathematical model of M-sequence generation which allows to compute the polynomial with the required M-sequence structure. The computer simulation of data transferring in specialized closed circuit television computer system with the covert channel is performed.
