MUTUAL AUTHENTICATION SYSTEM Russian patent published in 2022 - IPC H04L29/06 H04L9/32 H04W12/69 H04W12/50 

FIELD: wireless communication.

SUBSTANCE: invention relates to a wireless communication system that provides one-way authentication of a respondent device by means of an initiator device and mutual authentication of both devices. The initiator can have a message module and a state machine. The initiator is actuated by obtaining a responder public key through an out-of-band action, and it sends an authentication request. The respondent sends an authentication response containing respondent authentication data based on the respondent confidential key and a mutual conduct status indicating mutual authentication to enable the respondent device to receive an initiator public key through the respondent out-of-band action. The initiator state machine is made with the possibility of providing a mutual authentication state activated when receiving the mutual conduct status to wait for mutual authentication.

EFFECT: prevention of long periods of timeout during wireless communication while simultaneously enabling the initiator to report communication errors to the user within a short time.
