Abstract
The embodiment of the present invention discloses a key negotiation method, user equipment and short distancecommunication controlnetwork element. The method includes: the near-field communication controlnetwork element receives registration request information sent by the user equipment; sends security context request information to the control network element according to the registration request information; receives security context request information sent by the control network element according to the security context request information. context response information; determine the negotiation key according to the security context response information; send registration response information to the user equipment, so that the user equipment generates a negotiation key according to the registration response information; the negotiation key is used The key for the interaction between the user equipment and the short-range control network element. The key negotiation method, user equipment and short-distance communication controlnetwork element provided by the embodiment of the present invention realize the key negotiation between the UE and the short-distance communication control network element without changing the existing ProSe architecture.
Description
[0001] This application claims the priority of the Chinese patent application with the application number 201410109503.2 and the title of the invention "key agreement method, user equipment and short-distance communication control network element" submitted to the China Patent Office on March 21, 2014. technical field [0002] The present invention relates to the technical field of communication, and in particular to a key negotiation method, user equipment and short-distance communication control network elements. Background technique [0003] Proximity Service (ProSe) technology is mainly applied to establish a secure communication channel between two user equipments (UEs) for end-to-end data transmission in a short distance, so that data can be exchanged safely. In the existing ProSe system architecture, such as figure 1 As shown, it includes UE, Evolved Packet Core (EPC), ProSe Function and Evolved Universal Terrestrial Radio Access Network (E-UTRAN). The UE communicate...
