针对现有车载自组织网络(VANET,Vehicular Ad-hoc Network)存在的安全威胁及车辆与车辆之间,车辆与基础设施之间建立可信的连接问题,提出基于ECDH(Elliptic curve-Diffie-Hellman)公钥加密算法和UsbKey双因子身份鉴别的方案,设计出新的双向安全认证协议及详细算法,并对协议方案进行详细的安全分析,分析表明该认证协议具有更强的安全性、保密性及抗攻击能力。
Aiming at the security threats existing in Vehicles Ad-hoc Network (VANET) and the credible connection between vehicles and vehicles, and vehicles and infrastructure, this paper proposes an Elliptic Curve-Diffie-Hellman ) Public key encryption algorithm and UsbKey two-factor identity authentication scheme, a new bidirectional security authentication protocol and a detailed algorithm are designed, and a detailed security analysis is carried out on the protocol scheme. The analysis shows that the authentication protocol has stronger security and confidentiality And anti-attack ability.
