The authentication algorithm for machine-to-machine communication devices via the MQTT Protocol is considered, which allows verifying the device legality without sending the password. The algorithm protects the Internet of things network from unauthorized access, ensures confidentiality by generating a common session key, and provides protection against attacks of the "man in the middle" and others. The obtained experiment results showed noticeable performance improvement compared to the TLS Protocol. The cryptographic strength of the proposed algorithm is based on the discrete logarithm problem. The main advantage of the algorithm is the ability to authenticate in one requestresponse cycle.
