SDN-based privacy protection switching authentication method and 5G heterogeneous network

Abstract

The invention belongs to the technical field of communication network security, and discloses an SDN-based privacy protection switching authentication method and a 5G heterogeneous network. An SDN controller is located in a 5G data center, and an authentication switching module is placed in the SDN controller as an application and is used to monitor and predict the locations and paths of 5G users;relevant base stations are prepared or appropriate base stations are selected before the switching of the 5G users, and thus the seamless switching authentication can be ensured; and the 5G users control the own security context information and transfer the information to a target base station (BS), wherein the security context information can be directly used for mutual authentication between the users and the BS. According to the scheme of the invention, the 5G users can directly implement the bidirectional authentication with the target BS without adopting complicated communication protocols between the BSs or contacting with other third-party entities, and thus signaling flows can be simplified. According to the scheme of the invention, strong security attributes including anonymity,unlinkability and traceability can be provided, and compared with the prior art, a lower switching cost can be realized.

Description

technical field [0001] The invention belongs to the technical field of communication network security, and in particular relates to an SDN-based privacy protection switching authentication method and a 5G heterogeneous network. Background technique [0002] With the development of smart devices and mobile communication technology, mobile business data is growing rapidly, and the wireless communication network architecture is constantly upgraded and updated. Traditional cellular networks are facing a major transformation from voice services to data services, from circuit switching (CS) to packet switching (PS), from uniform networks to high-density, different-shaped networks, etc. With the maturity of IP network, the development of hardware and software technology and the significant reduction of small base stations, Heterogeneous Network (HetNet) technology has been highly valued by the industry and academia. In order to comply with this trend, the heterogeneous network (He...
