Firstly, the dual-chain decentralized storage structure of consortium blockchain-private blockchain was adopted to ensure the security of communication data. Then, the identity-based digital signcryption algorithm and the discrete central binomial distribution-based ring signature scheme were used to solve the security problem in the communication process. Finally, the Dynamic-layering and Reputation-evaluation Practical Byzantine Fault Tolerant mechanism (DRPBFT) was proposed, and the edge computing technology was combined with the cloud computing technology, so as to solve the high time delay problem. Security analysis shows that the proposed scheme can guarantee the security and integrity of data during the information sharing process. Experimental simulation and performance evaluation results show that, DRPBFT has the time delay within 6 s, and effectively improves the throughput of the system. The proposed IoV scheme effectively improves the enthusiasm of vehicle data sharing, leads to more efficient and stable operation of IoV system, and achieves the real-time and efficient purposes of IoV. %U http://www.joca.cn/EN/10.11772/j.issn.1001-9081.2020121938
