Abstract

A blockchain-based privacy protection trust model for the Internet of Vehicles. Vehicles on a road generate and broadcast messages by means of a vehicular ad-hoc network in order to share traffic information of the surroundings to improve traffic efficiency and safety. However, because of the untrustworthy network environment of vehicular ad-hoc networks, vehicles can easily expose private information and cannot determine whether a received message is reliable. In the present invention, a vehicle is caused to send a message anonymously by means of ring signature technology, preventing the vehicle from being tracked by a malicious vehicle. Messages sent by vehicles are evaluated and filtered by means of a blockchain technology-based credibility evaluation mechanism, filtering out fake information therein. On the basis of the features of the blockchain itself, it is ensured that vehicle credibility will not be subject to malicious tampering, and real-time synchronous updating of vehicle credibility is made possible, further improving the security and usability of vehicular ad-hoc networks.
