Flow-aware approach of evaluating probability of compromise in combined structure network

A flow-aware approach of evaluating the probability of compromise in combined structure network is presented. Experimental and numerical examples have been used to analyze the influence on flow compromising of security parameters of network links and fragments. It is shown that the proposed approach gives more precise results of calculation the probability of flow compromise when using overlapping routes with series-parallel and combined structure up to 30% in most of cases in relation to the known method, which is used for overlapping paths.
