SIP-Based Method, Apparatus and System for Secure Communication Between MTC Devices

摘要

Provided is a SIP-based method for secure communication between MTC devices, including that an SIP server establishes a secure connection with a source MTC device and a secure connection with a target MTC device respectively through a GBA manner or a GBA-push manner, the SIP server generates an application layer session key, sends the application layer session key to the source MTC device through the secure connection between the SIP server and the source MTC device, and sends the application layer session key to the target MTC through the secure connection between the SIP server and the target MTC device. A SIP-based system and apparatus for secure communication between MTC devices are also provided. The establishment of a secure connection between MTC devices based on an SIP protocol can be implemented.

1. A Session Initiation Protocol (SIP)-based method for secure communication between Machine Type Communication (MTC) devices, comprising:
establishing a secure connection between an SIP server and a source MTC device and a secure connection between the SIP server and a target MTC device respectively through a Generic Bootstrapping Architecture (GBA) manner or a GBA-push manner; generating, by the SIP server, an application layer session key; sending, by the SIP server, the application layer session key to the source MTC device through the secure connection between the SIP server and the source MTC device; sending, by the SIP server, the application layer session key to the target MTC through the secure connection between the SIP server and the target MTC device.
