Enhanced method of calculating the probability of message compromising using overlapping routes in communication network

The enhanced method of calculating the probability of message compromising in a communication network when using overlapping routes with series-parallel and combined structure are considered. A number of numerical examples have been used to analyze the influence on message compromising of security parameters belonging to certain elements (links) and fragments of the network. It is shown that the proposed method gives more precise calculation results from 20% to 40% in most of initial data in comparison to the known method used for overlapping paths.
