The Markov Model for a Multiphase Security System with the Partial Concurrent Service

Anatoly Yermakov
A cryptographic protocol is not only an algorithm but also a procedure for exchanging data between different network subscribers, associated with the message exchange at different levels. In this case, the problem of minimizing the number of protocol implementation levels depending on the task size is relevant. The algorithm graph for finding the state probabilities of the multiphase mixed-type queuing system is derived. The characteristic parameters are determined: performance, downtime rate, and balancing rate. The example of calculating system performance is considered.
