Description
Summary:In this paper, we consider the NB-Fi protocol that provides secure communication between IoT devices and control servers. It is shown that the version of the protocol proposed in the draft national standard of the Russian Federation does not provide confidentiality and data integrity in the considered adversary model. A variant of the protocol modification that provides these properties is proposed.
