Mutual authentication method and system with network in machine type communication
A method for a Mobile Mobility Entity (MME) to carry out mutual authentication with a group of Machine Type Communication (MTC) devices includes receiving group-related authentication data from a leader, transmitting the received information and an identification number of the MME, to a HSS, receiving from the HSS a random value, an Authentication Vector and information of group members, broadcasting the random value and the first authentication token to the MTC device group based on information received from the HSS, receiving from the leader a leader authentication response that the leader generates by using a local master key value calculated by using the first secret key value, authenticating the leader by comparing the leader authentication response with a leader authentication value received from the HSS, and authenticating members within the MTC device group according to the leader authentication result.
