N2 - The Internet of Vehicles (IoV) greatly improves the traffic environment and life efficiency using messages shared between vehicles. However, due to its complex network structure and high mobility, the messages shared between vehicles are not always reliable. To this, we propose a trust management system of IoV based on blockchain, which formalizes a complete vehicle reputation value calculation scheme to deal with the problem of calculating the credibility of messages. The proposed scheme can detect vehicles that send malicious messages and reduce their reputation values for punishing according to the rating mechanism. In addition, we design a blockchain-based data storage system that can prevent attackers from tampering with the reputation values stored in roadside units (RSUs). In view of the lack of calculation basis when roadside units verify the block, we also store the rating list it. Finally, we use the consensus mechanism that combines PoW and PoS to ensure that vehicles with a large change in reputation can be updated to the blockchain first. The simulation results show that the proposed scheme has an obvious limitation on malicious vehicles, and improves the accuracy of the vehicles' judgment of events based on the received messages.
