摘要:

针对5G-V2X场景中大量车辆执行切换认证的效率问题,提出了一种基于轨迹预测的安全高效群组切换认证协议。首先,通过预测车辆轨迹,提前完成密钥协商协议。其次,通过用户分组算法将具有移动相关性的车辆视为同一群组,再采用无证书聚合签名技术批量验证群组内所有车辆。再次,针对聚合签名技术易遭受拒绝服务攻击的弊端,采用二分查找法快速定位恶意用户,提高群组切换认证协议的效率。最后,利用形式化验证工具Scyther对所提协议进行了安全性分析,与现有最优协议相比,所提协议的计算效率提高了30%。

Abstract:

Aiming at the efficiency issue of handover authentication for a large number of vehicles in the 5G-V2X scenario, a secure and efficient group handover authentication protocol based on trajectory prediction was proposed.Firstly, the effect of completing key agreement protocol in advance was achieved by predicting vehicle trajectories.Secondly, vehicles with mobility relevance were treated as the same group through user grouping algorithms, and then all vehicles within the group were batch verified using certificateless aggregation signature technology.In addition, to address the vulnerability of aggregated signature technology to DoS attacks, a binary search method was used to quickly locate malicious users and improve the efficiency of group handover authentication protocol.Finally, the security analysis of the protocol was conducted using the formal verification tool Scyther, and compared with the existing optimal protocol, the computational efficiency is improved by 30%.

Key words: 5G-V2X, group handover authentication, user grouping, certificateless aggregation signature, Scyther
