摘要:

车辆身份是车辆在可信中心的唯一合法标识,它直接关联车辆用户的信息,对车辆身份的匿名认证是用户隐私保护的一种体现。基于此,以无证书签名方案为基础,设计一种车载网络匿名身份认证协议。该协议无需证书管理且不存在密钥托管问题。对协议的安全性与性能进行分析,结果表明,该协议认证效率明显高于基于证书的认证协议与基于身份的认证协议,同时满足匿名性、不可否认性、相互认证性、条件隐私保护性及抗重放攻击性。

Abstract:

Vehicle identity is the vehicle’s exclusive user legitimate identification stored in trusted centre,which is directly related to the vehicle user’s information,so that its anonymous authentication reflects the protection of user privacy.Based on a certificateless signature scheme,this paper proposes an anonymous authentication protocol without the management of certificate or the problem of key escrow.The security and performance of the proposed protocol are analyzed.Result shows that the protocol has higher efficiency than the certificate-based authentication protocol and the identity-based authentication protocol.It is anonymous,undeniable,mutually authenticated,privacy preserving and anti-attack.

Key words: vehicular network, vehicle identity, privacy preserving, anonymous identity authentication, certificateless signature
