MACHINE TYPE COMMUNICATION DEVICE GROUP MANAGEMENT METHOD AND SYSTEM BASED ON GENERIC BOOTSTRAPPING ARCHITECTURE

摘要

The present invention discloses a Machine Type Communication (MTC) device group management method based on Generic Bootstrapping Architecture (GBA). The method is applied in a system including the MTC device, a Bootstrapping Sever Function (BSF), and a Machine to Machine Service Center (M2M-SC). The method includes the following steps: when a first MTC device negotiates with the M2M-SC and determines to join the MTC device group with a group identifier G-ID, a first session key is established between the first MTC device and the M2M-SC via a first GBA process between the first MTC device, the BSF and the M2M-SC; the M2M-SC encrypts, with the first session key, the G-ID of the MTC device group and the group key Kg of the MTC device group and then transmits them to the first MTC device. With the present invention, a security management can be performed on group members of the MTC device group.
