摘要
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。
For the security threats existing in the Vehicular Ad-hoc Network（VANET） and the trusted connection between vehicle to vehicle and vehicle to infrastructure,a strategy based on combination of elliptic curve-Diffie-Hellman public key encryption algorithm and UsbKey two-factor authentication method is proposed,and a novel two-way authentication protocol,including the algorithm,is designed.The security of protocol stragegy is also analyzed in detail,and the analysis result indicates that the authentication protocol is of much stronger security,confidentiality and anti-attack capability.
