摘要
车联网中的身份认证方案是解决车联网许多安全和隐私问题的有效途径之一。然而,现有认证方案多数没有关注单点故障问题或者存在信息泄露。针对上述问题,提出了一种车联网中基于阈值的边缘辅助身份认证方案。该方案在保护车辆真实身份信息的前提下,由多个边缘节点协同认证车辆,避免了单点故障问题。同时,在初始合作认证阶段生成令牌用于快速切换认证阶段的身份认证,在不与多个边缘节点交互下实现基于身份认证的快速切换,有效减少了认证延迟。若认证过程中出现异常,云计算中心也可以对恶意车辆进行追踪,还原其真实身份并进行撤销。安全性分析和仿真实验表明,所提方案是安全有效的。最后对提出方案进行了总结,并对未来工作作出展望。
The identity authentication scheme in vehicular Ad hoc network is one of the effective ways to solve many security and privacy problems in the Internet of Vehicles.However,most of the existing authentication schemes do not focus on single points of failure or information leakage.In order to solve the above problems,this paper proposed a threshold-based edge-assisted identity authentication scheme in VANET.On the premise of protecting the real identity information of the vehicle,the solution cooperated with multiple edge nodes to authenticate the vehicle,thereby avoiding the issue of a single point of fai-lure.At the same time,in the initial cooperative authentication stage,the scheme generated a token for rapid switching of identity authentication in the authentication stage,and achieved rapid switching based on identity authentication without interacting with multiple edge nodes,which effectively reduced the authentication delay.If there was an abnormality in the authentication process,the cloud computing center could also track the malicious vehicle,restore its real identity and revoke it.The security analysis and simulation experiments show that the proposed scheme is secure and effective.Finally,it prospected the proposed scheme summarized and the future work.
