Embodiment

[0075] image 3 It is a schematic diagram of the system architecture for realizing the MTC server shared key in the embodiment of the present invention, such as image 3 As shown, the system includes: MTC equipment (equipment used by users for machine type communication), subscriber identification card (such as UICC, generally installed in MTC equipment), BSF (Bootstrapping Server Function) and MTC server (provides MTC for MTC users business), HSS (Home Subscriber System, user home server). Among them, the BSF and the MTC device implement authentication through the AKA protocol, and negotiate a session key K that is subsequently used for communication between the MTC device and the MTC server NAF , the BSF can set the life cycle of the key according to the local policy; optionally, in the system based on the present invention, the HSS can also save the relationship between different MTC servers, such as saving different Relationship between MTC servers. When the relationshi...

Abstract

The invention discloses a method for MTC servers to share keys. When an MTC device establishes a secure connection with a first MTC server through a GBA process and performs secure communication, it can send request information to a second MTC server (including the MTC device and the first MTC server). The host identification NAF-ID1 of the boot identification B-TID and the first MTC server being used); The second MTC server sends an authentication request to the BSF (including the host identification NAF-ID2, B-TID and NAF-ID1 of the second MTC server ); After the BSF verifies that NAF-ID2 and NAF-ID1 are valid, it generates a session key KNAF according to B-TID and NAF-ID1, and sends it to the second MTC server. The present invention also correspondingly discloses a system for MTC servers to share keys. Through the present invention, MTC equipment can be safely communicated with multiple MTC servers at the same time, and the use efficiency of network resources is improved.

Description

technical field [0001] The present invention relates to a mobile communication system and a machine type communication (Machine Type Communication, MTC) technology, in particular to a method and a system for MTC servers to share keys. Background technique [0002] MTC refers to the general term for a series of technologies and their combinations that use wireless communication technology to realize data communication and exchange between machines and machines, and between machines and people. Machine to machine (M2M) has two layers of meaning: the first layer is the machine itself, which is called a smart device in the embedded field; the second layer means the connection between machines, connecting machines to Together, so as to make human life more intelligent. MTC has a wide range of applications, such as intelligent measurement, remote monitoring, tracking, medical treatment, etc. Compared with traditional human-to-human communication, MTC devices (M2M Devices) have a...
