The one-time password method is one of the most common and effective methods of authentication of the source and receiver of information. The main threat to the trusted communication channel of exchange information is a potential attacker who randomly generates and transmits messages to the receiver, that may be mistakenly perceived as an authenticated source. This article discusses an authentication method based on a modified one-time password method, in which the decision on the legality of the received message is made not only on the basis of the content of its verification sequence but also on the basis of the history of the received verification messages. The parameters of the algorithm for generating authenticated data are analyzed, the influence of these parameters on the probability of authentication errors in the communication channel is investigated.
