Abstract

Embodiments of the present invention provide a method and related equipment for generating a group key. The method includes: obtaining the group ID of the group where the machine type communication MTC device is located; obtaining the group communication root key corresponding to the group ID; generating the group key corresponding to the group ID according to the group communication root key; The group key encrypted by the access layer key, so that the MTC device can decrypt it according to the access layer key of the MTC device to obtain the group key. According to the above technical solution, the base station can distribute the group key corresponding to the group where the MTC device is located to the MTC device, so that the MTC devices in the same group can use the same group key to carry out group communication normally, and in the base station, only The same group key needs to be kept for the same group, so that the complexity of base station operation can be reduced, the number of keys maintained and managed by the base station can be reduced, and the performance of the base station can be improved.

Description

technical field [0001] The present invention relates to the field of communication, and more particularly, to a method and related equipment for generating a group key in the field of communication. Background technique [0002] Machine to Machine (M2M) technology is the integration of wireless communication and information technology, which means that machines can communicate directly without human intervention. There are many types of M2M applications, including automatic instrumentation, remote monitoring, industrial safety and ship automation, payment systems, and vehicle remote control. [0003] There are three modes of M2M, including machine-to-machine, machine-to-mobile and mobile-to-machine. In M2M, M2M devices can access the network through long-distance connection technology and short-distance connection technology. The long-distance connection technology involved includes Global System for Mobile communications (Global System for Mobile communications, GSM), Gene...
