Conventional blockchain consensus protocols tailored for the Internet of Vehicles (IoV) usually face low transaction throughput, high latency, and elevated communication overhead issues. To address these issues, in this paper, we propose ESBCP, an efficient secure protocol IoV environment. Firstly, considering significant performance differences among nodes IoV, designed a model IoV. Roadside units execute trust evaluation mechanism to select high-quality vehicle process, thereby reducing likelihood malicious cluster. Secondly, node partition strategy adapt dynamic feature Finally, addressing mobility introduced unique list. Vehicle can promptly with reliability from list communicable join their list, while also removing Combining strategies, DK-PBFT, improved Practical Byzantine Fault Tolerance algorithm. The algorithm meets efficiency requirements vehicular networks. Through theoretical analysis, ESBCP could prevent external internal security risks overhead. Experimental verification demonstrated that effectively reduces latency improves throughput. Our proposed be used other application scenarios require efficiency.
