摘要: 智能交通系统中行驶车辆需要传递各种实时交通信息或位置信息,这些信息的真实性、不可伪造性、向前向后安全、可追踪等性能在提高交通效率、减少交通事故、提升出行体验等方面发挥着极其重要的作用。通过研究基于椭圆曲线的数字签名算法,设计了一个可溯源车联网匿名签名和批量验证方案。可信机构初始化系统并为车辆用户设置假名,发送相应的用户公钥和签名私钥;车辆用户对需要发送的消息进行签名,并发送路侧单元进行验证,验证方式包含单个验证和批量验证,其中批量验证又包含Type I型和Type II型两种验证方式;进行了正确性和安全性证明,并通过仿真实验与已有方案进行比较,该方案带宽需求和计算代价更少;最后进行了全文总结和下一步研究展望。

Abstract: In intelligent transportation systems, vehicles need to transmit various real-time traffic information or location information. The authenticity, unforgeability, forward and backward safety, and traceability of this information play an extremely important role in improving traffic efficiency, reducing traffic accidents, and enhancing travel experience. A traceable anonymous signature and batch verification scheme for connected vehicles is designed by studying a digital signature algorithm based on elliptic curves. Firstly, the trusted institution initializes the system,sets a pseudonym for the vehicle user, and sends the corresponding user public key and signature private key. Then the vehicle user signs the message to be sent and sends it to the roadside unit for verification. The verification method includes single verification and batch verification, and batch verification includes two forms: Type I and Type II. Subsequently, the correctness and security of the proposed scheme are demonstrated, and simulation experiments are conducted to demonstrate that compared with existing schemes, this scheme has more advantages in achieving performance efficiency. Finally, a summary of the entire paper and prospect for future research is presented.
