Mukhin V. Methods and means for the design of the multicomputers systems based on the multi-channel environments for the data transfers

The thesis is dedicated to the solving of the scientific and technical problems in the field of the design of the distributed multicomputer systems (MCS) with the goal to improve the indicators of the data transfer rates, reliability and security of processed data. The prognostic model of the data transfer rates, reliability, and security level in the MCS, as well as the integrated model, that allows receive the optimal indicators of the MCS characteristics are developed. There is proposed the method for selection of the secured routes for the data transfers based on the analysis of the complex state of MCS nodes. There is proposed a method of the forming of the trust level to the nodes based on dynamic ranking of the information by its value. A theory of risk assessment of the security violation in the distributed multicomputer systems, based on the analysis of critical situations in decision-making, is suggested. Experimental researches of the security level of MCS resources, as well as the fractal properties of distributed multicomputer systems was performed.
