Disclosed is a session initiation protocol (SIP) inter-machine type communication (MTC) device secure communications method, comprising: an SIP server establishing secure connections with a source MTC device and a target MTC device respectively through a generic bootstrapping architecture (GBA) manner or a GBA-push manner; the SIP server generating an application layer session key; sending the application layer session key to the source MTC device by using the secure connection between the SIP server and the source MTC device; sending the application layer session key to the target MTC device by using the secure connection between the SIP server and the target MTC device. Also disclosed are an SIP based inter-MTC device secure communications system and device. Through the present invention, a secure connection can be established between MTC devices based on an SIP protocol. |
