摘要：

The Internet of vehicles enables vehicles to disseminate information to improve traffic safety and efficiency. However, in an untrusted environment, how to effectively implement trust assessment and instantly update consistent trust values among multiple road side units (RSUs) remains a challenging problem. Trust management solution for internet of vehicles based on logistic regression and blockchain is proposed. First, the vehicle can calculate the direct trust value and the recommended trust value for it through the historical behavior of the communication partner, and use the logistic regression algorithm to calculate the comprehensive trust value, and then upload it to the nearby RSU, which will package the data into a block. Second, a hybrid consensus mechanism based on proof of stake (PoS) and practical Byzantine fault tolerance (PBFT) is proposed. RSUs with larger stakes are more likely to be selected as miners, and work together with authorized RSUs to verify the correctness of blocks, making the blocks with large changes in trust value can be published instantly. Finally, safety analysis and performance simulation show that the scheme is effective and feasible in calculating and storing vehicle trust value. © 2024 Journal of Computer Engineering and Applications Beijing Co., Ltd.; Science Press.
