摘　　要：为实现车联网相关数据的安全传输和隐私保护,提出了一种基于车端量子密钥的车联网数据访问控制方案。设计了基于预充注量子密钥的身份认证和密钥协商机制,提出了基于量子随机数发生器的车辆数据访问控制方案,在车载通信终端集成量子随机数发生器以生成量子加密密钥,并由车辆所有者对来自外部设备的车联网数据访问请求进行管控,以防止非授权访问、高权限人员恶意侵入和车辆隐私数据的不当开放。最后,对提出的方案进行了安全性和性能分析,结果表明,该方案具有较强的安全性,具有比其他主要方案更小的计算开销(0.395 ms)和通信开销(420 B)。To realize secure transmission of vehicular network related data and privacy protection,this article proposed a quantum key based identity authentication and data access control scheme for the vehicular networks.An identity authentication scheme and key agreement mechanism based on pre-charge quantum keys were designed,vehicle data access control scheme based on quantum random number generator was proposed to generate quantum encryption keys,allowing the vehicle owner to control access requests for vehicle networking data from external devices to prevent unauthorized access,malicious intrusion by high-privileged personnel and improper opening of vehicle privacy data.Finally,this article conducted security and performance analysis,analysis results show that this scheme has good security,with a computational cost of 0.395 ms and a communication cost of 420 B,which are lower than that of other schemes.
