Method and system of securing group communication in a machine-to-machine communication environment
First Claim
1. A method of securing group communication in a machine-to-machine (M2M) communication environment, wherein the M2M communication environment includes a plurality of machine type communication (MTC) groups, and wherein each of the plurality of MTC groups includes a plurality of MTC devices, the method comprising:
- receiving, by a first network entity securing group communication of MTC devices, subscription information of the MTC devices associated with an MTC group from a second network entity managing the subscription information, the subscription information including a group identifier associated with the MTC group to which the MTC devices belong;
generating, by the first network entity, a unique group key for securing communication with the MTC devices associated with the MTC group in the M2M communication environment, based on the subscription information of the MTC devices; and
securely providing, by the first network entity, information on the unique group key to the MTC devices associated with the MTC group,wherein the MTC devices securely receive at least one broadcast group message using the information on the unique group key.
