Issue of packets loss on time of overload on network nodes and connection can be resolved on account of translate an part of traffic at secondary line thru unloaded nodes and connections. Packet loss is increase at increase time of authentication. A method for shortening the execution time of the authentication procedure is proposed. The experiment and the comparative analysis of the performance, existing and proposed algorithms of authentication has been carried out. The advantage of the proposed method has been revealed. It possible to shorten the authentication time by more than 7 times.
