FIELD: information technology.
SUBSTANCE: disclosed is a method which is realised by a mobile device (100) in order to authenticate communication with a network (400), in which keys are generated (on step S610, 620) using voice encryption and authentication for cellular communication and an authentication key is then generated (on step S630) based on said keys. The authentication key is used to generate the expected message authentication code used for network authentication according to a security protocol for key matching and authentication.
EFFECT: high reliability of secure wireless communication.
