A Massive D2D Anonymous Discovery Authentication and Key Agreement Method

Abstract

The invention belongs to the technical field of communication network security, and discloses a massive D2D anonymous discovery authentication and key agreement method; an initialization authentication stage; an anonymous device discovery stage based on prefix encryption; a mutual authentication and key agreement stage based on batch verification; key confirmation stage. The present invention is designed according to the 3GPP standard, so there is no need to change the communication equipment in the standard, and it can be applied to the network of all LTE-A / 5G mobile scenarios; the general structure of the device discovery and authentication mechanism proposed by the present invention can realize neighboring devices Discovery, mutual authentication, key negotiation, and identity privacy protection; the fast key confirmation method based on the CRT mechanism proposed by the present invention effectively reduces the number of signaling; reduces signaling overhead, communication overhead, and transmission overhead; can be directly implemented Direct mutual authentication between massive D2D devices, and can resist all currently known attacks.

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...
