MUTUAL AUTHENTICATION METHOD AND SYSTEM WITH NETWORK IN MACHINE TYPE COMMUNICATION, KEY DISTRIBUTION METHOD AND SYSTEM, AND UICC AND DEVICE PAIR AUTHENTICATION METHOD AND SYSTEM IN MACHINE TYPE COMMUNICATION

摘要

A method of performing a mutual authentication with a group of an MTC (Machine Type Communication) device by an MME (Mobile Mobility Entity) of a network includes the steps of: (a) requesting authentication data related to the group of the MTC device from an HSS (Home Subscriber Server); (b) receiving a group master key and information of the group members based on an IMGI (International Mobile Group Identity) related to the group of the MTC device from the HSS; (c) generating an authentication token based on the received group master key and the group member information; (d) receiving the authentication token to perform an authentication with the network by the MTC device, and requesting generation of the temporary group key and a response value by using the group master key based on the authentication performance resu and (e) receiving the temporary group key and the response value from the MTC device to perform an authentication of the MTC device.
