Mass D2D anonymous discovery authentication and key negotiation method

Abstract

The invention belongs to the technical field of communication network security, and discloses a mass D2D anonymous discovery authentication and key negotiation method. The method includes an initialization authentication stage; an anonymous device discovery stage based on prefix encryption; a mutual authentication and key negotiation stage based on batch verification; and a key confirmation stage.According to the scheme design carried out according to the 3GPP standard, communication equipment in the standard does not need to be changed, and the method can be applied to networks of all LTE-A / 5G mobile scenes; the general structure of the equipment discovery and authentication mechanism provided by the invention can realize discovery, mutual authentication, key negotiation and identity privacy protection of adjacent equipment; according to the rapid key confirmation method based on the CRT mechanism provided by the invention, the signaling number is effectively reduced; the signaling overhead, the communication overhead and the transmission overhead are reduced; direct mutual authentication between a large number of D2D devices can be directly realized, and all known attacks at present can be resisted.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to a massive D2D anonymous discovery authentication and key agreement method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: With the development of smart terminals and the explosive growth of wireless communication data volume, in order to meet higher speed, lower delay, larger wireless area capacity and lower In terms of energy consumption per unit of service, 3GPP proposes the fifth generation mobile communication technology (5G). 5G wireless networks are often combined with LTE-A, WLAN, WiMAX and other wireless access technologies to form a high-density heterogeneous network (HetNet), improve network capacity, and provide high-speed coverage and seamless user experience. However, the mutual interference among complex macro, small cells, and micro cells limits the increase of co...
