Method for Realizing Secure Communications among Machine Type Communication Devices and Network Entity
First Claim
1. A method for realizing secure communication between machine type communication (MTC) devices, comprising:
- creating, by a network entity, an MTC device group for a directly-communicating MTC device, and saving MTC device group information corresponding to the MTC device group and MTC device information of an MTC device contained in the MTC device group, wherein the MTC device group information comprises MTC device group identification information and MTC device group key information; and
sending, by the network entity, the MTC device group information of the MTC device group, to which the MTC device belongs, to the MTC device.
