Group pre-switching authentication method and device based on trusted relay

Abstract

The invention discloses a group pre-switching authentication method and device based on a trusted relay, and the method comprises the steps: carrying out the group authentication of a user terminal through the trusted relay, and recording the information of the user terminal passing the authentication to a pre-switching set; predicting the track of the user terminal in the pre-switching set to obtain a target base station of the user terminal; and comparing the current base station coverage range of the user terminal with the position information of the user terminal, and switching the user terminal to a target base station by using a trusted relay when the position of the user terminal exceeds the current base station coverage range. The group pre-switching technology and the trusted execution technology are combined, group switching can be rapidly and safely carried out, it is guaranteed that the 5G network can provide smooth and safe communication experience for users in the train running process, the switching problem of mass terminal devices in the current 5G network in the high-speed moving process is solved, and the user experience is improved. The method is high in applicability and safety, and switching overhead consumption is reasonable.

Description

technical field [0001] This application relates to the field of information security technology, in particular to a trusted relay-based group pre-handover authentication method and device. Background technique [0002] The rapid development of 5G networks has promoted the implementation of new services and new scenarios. The International Telecommunication Union (ITU) defines Enhanced Mobile Broadband (Enhanced Mobile Broadband, eMBB), Massive Machine-Type Communications (Massive Machine-Type Communications, mMTC) and Ultra-reliable and Low Latency Communications (Ultra-reliable and Low Latency Communications). , uRLLC) three typical 5G application scenarios. Among them, mMTC supports the connection of a large number of terminal devices, allowing the base station to have a greater ability to manage a large number of network interruptions, and uRLLc focuses on providing services for scenarios with stricter delay and reliability such as industrial Internet and autonomous driv...
