Abstract: In Vehicular Networks, vehicles share information to improve traffic efficiency and safety. However, false information incurs severe damage or injuries because of malicious nodes. Althogh many schemes have been implemented for detection of false information,, there are problems concerning inadequate data security, large processing delay, weaker precision in detecting malicious nodes. In this paper, we put forward a Blockchain-based incentive-compatible trust management system. It provides a succinct and effective incentive mechanism to stimulate vehicles to broadcast road-related emergency information and vicinity vehicles to evaluate its timeliness. We also propose a novel method to calculate the reputation score to reflect the history behavior better. The transactions on the reputation scores are recorded in a consortium Blockchain consisted by Road Side Unit (RSU). The system has been experimentally validated to have a lower time delay and higher accuracy, and more accuracy reputation scores in Vehicular Networks.
