An authentication method for multi-server architecture in the Internet of Vehicles cloud environment

Abstract

The invention discloses an authentication protocol for a multi-server architecture under the Internet of Vehicles cloud environment, which includes the following steps: (1) system initialization: system parameters are generated by trusted organizations TAs; (2) server and vehicle registration, for each server Set a unique identity and set a unique identity for the vehicle, and equip the vehicle with a tamper-proof device TPD installed on the vehicle; (3) Two-way authentication between the server and the vehicle: the vehicle calculates the signature through the TPD and will contain The vehicle signature request message is sent to the server and the server calculates the signature information after accepting the vehicle's request, and generates a response message containing the signature and sends it to the vehicle; (4) Key negotiation: establish two-way authentication between the vehicle and the server, and negotiate session keys sk, followed by encrypted secure communication. In the present invention, after the user registers with the trusted institution, it is not necessary to register at each server, which improves the calculation efficiency and communication efficiency of the user and the server.

Description

technical field [0001] The invention relates to the field of Internet of Vehicles and wireless communication security, in particular to an authentication method for multi-server architecture under the cloud environment of Internet of Vehicles. Background technique [0002] Vehicle Networking (Vehicular Adhoc Networks, VANETs) is the application of Internet of Things technology in the field of transportation system, and it is also an important part of the next generation mobile Internet network. The Internet of Vehicles system includes three participants: the on-board unit OBU (On Board Unit) deployed on the vehicle, the roadside unit RSU (Road Side Unit) fixed on both sides of the road, and the trusted agency TA (Trust Authority). In the Internet of Vehicles, the highly intelligent OBU can link with the urban traffic information network, smart grid, and community information network according to its own conditions, and obtain instant information anytime and anywhere, thereby...

Problems solved by technology

[0004] In 2016, Xie Yong and others first proposed an authentication protocol for multi-server architecture under the VCC environment. This protocol writes the system master key into the tamper-resistant device. However, the tamper-resistant device cannot resist side-channel attacks. Through side-channel attacks, Such as power analysis and laser scanning, can effectively extract sensitive data from tamper-resistant devices. Once a vehicle is compromised, the entire VANETs system will no longer be safe
