Heterogeneous network unified authentication method based on physical layer safety

Abstract

The invention relates to a heterogeneous network unified authentication method based on physical layer safety. The heterogeneous network unified authentication method based on the physical layer safety comprises the steps that the unified identity information of a terminal is obtained by an authentication center; physical layer random authentication parameters are generated by the terminal and an access point; the physical layer random authentication parameters are reported to the authentication center by the access point; authentication data are generated by the authentication center through a root key of the terminal and the physical layer random authentication parameters, and the authentication data are transmitted to the terminal; the access point and the authentication center are authenticated by the terminal through the root key, the physical layer random authentication parameters and the authentication data of the authentication center, and terminal authentication data are generated and transmitted to the authentication center; the terminal is authenticated by the authentication center through the root key of the terminal, the physical layer random authentication parameters and the terminal authentication data; the physical layer random authentication parameters are simultaneously updated by the terminal and the access point, and continuous authentication is achieved. By means of the method, multi-party bidirectional identity authentication between various terminals and a heterogeneous network is achieved, and transparent transfer attacks of pseudo-base-stations and pseudo-terminals can be recognized and restrained.

Description

technical field [0001] The invention relates to a unified authentication method for heterogeneous networks based on physical layer security. Background technique [0002] The existence of pseudo-base stations and pseudo-terminals seriously interferes and threatens the secure communication of mobile communication networks, and poses a serious challenge to the information security of legitimate users, and this problem is more serious in heterogeneous wireless networks. In a heterogeneous wireless network, multiple wireless access technologies coexist, but for different wireless access technologies, their authentication mechanisms are different and have different security protection capabilities. Therefore, an authentication mechanism with a low security level will restrict the security performance of the entire heterogeneous wireless network. [0003] Current heterogeneous wireless networks generally use high-level encryption and authentication technologies to ensure the secu...
