Trusted and privacy-protected intelligent traffic light method and system based on v2x technology

Abstract

The invention discloses a trusted and privacy-protected intelligent traffic light method and system based on V2X technology. The method includes the following steps: system initialization; vehicle registration; a trusted organization TA verifies whether the vehicle identity is legal, and if legal, issues a reputation certificate; Vehicles that are about to pass through the intersection send request messages to traffic lights; traffic lights schedule vehicles based on the received request messages; traffic lights judge whether the actual behavior of vehicles is consistent with the vehicle request; trusted organization TA updates the reputation table. The invention can dynamically adjust the traffic lights according to the traffic conditions at the intersection, and change the display and duration, thereby effectively reducing the occurrence of traffic jams; while ensuring the authenticity and credibility of the information provided by the vehicle, the security of the private information is protected as much as possible Ensure that the traffic light system and vehicles are protected from various attacks by attackers, and ensure the privacy of vehicles and the security and credibility of the information received by the traffic light system during the driving of smart cars.

Description

technical field [0001] The invention belongs to the technical field of intelligent transportation, and in particular relates to a trusted and privacy-protected intelligent traffic light method and system based on V2X technology. Background technique [0002] With the integration of computer technology and vehicles, smart cars are also facing a series of security issues. The development of Internet of Vehicles technology is inseparable from network security technology. How to effectively protect the private information of vehicles while ensuring the safety of vehicles in the vehicle network to resist various hacker attacks is a technical problem that needs to be solved urgently. [0003] In the intelligent traffic light system, all vehicles arriving at the intersection will send a request message, and factors such as message type, quantity, and time determine the time for the green light to pass in each direction. In practical applications, there may be malicious vehicles t...
