摘　　要：在提高燃油效率和驾驶安全性上智能交通系统中的自动车辆排是一种优秀的解决方案。以物联网和5G通信技术为基础的自动车辆排在实现智能组队和行为通信过程中容易受到各种攻击,导致安全事故的发生。为此,结合边缘计算技术,提出一种基于属性的可撤销可追溯的访问控制方案。首先,使用基于属性的加密实现了细粒度的访问控制;其次,利用中国剩余定理动态更新排密钥实现消息的可撤销存储,并借助路边基础设施降低车辆侧的计算开销;接着在此基础上,利用椭圆曲线加密机制实现了用户的匿名和对恶意车辆的追溯。安全性分析和仿真实验结果表明,该方案在安全性和效率方面是可行的。AVP in intelligent transportation systems is an excellent solution for improving fuel efficiency and driving safety.Based on Internet of Things and 5G communication technology,autonomous vehicle platoons are susceptible to various attacks during the process of intelligent teaming and behavior communication,leading to safety accidents.To this end,an attribute-based revocable traceable access control scheme is proposed in combination with edge computing technology.Firstly,fine-grained access control is achieved using attribute-based encryption.Secondly,dynamic updating of the platoon key is implemented using CRT,allowing for the message’s revocable storage and reducing the computational overhead on the vehicle-side through the assistance of roadside infrastructure.Furthermore,an anonymous user and traceability of malicious vehicles are achieved using an elliptic curve encryption mechanism.Finally,through security analysis and simulation experiments,it is shown that the scheme is feasible in terms of security and efficiency.
