Abstract

Abstract: Due to complexity and inefficiency of existing anonymous authentication schemes when a VANET is large-scale，a new scheme based on CPK and blind signature is proposed in the elliptic curve domain.The protocols introduced by the proposed scheme are also presented in detail.The analysis result indicates that the proposed scheme not only satisfies security and privacy，but also has more efficiency compared with the existing schemes.

摘要： 针对现有车载自组织网络（Vehicular Ad-hoc Network，VANET）匿名认证方案在网络规模较大时存在复杂性和执行效率方面的问题，提出了一种基于盲签名和组合公钥（Combined Public Key，CPK）算法的认证方案，并对该方案所包含的认证协议进行了详细描述。安全性和执行效率分析表明，与现有方案相比提出的匿名认证方案在保证用户匿名性的同时还具有较高的执行效率。
