基于自证明公钥和零知识证明的身份认证协议

Authentication Protocol Based on Self-certified Public Key and Zero-knowledge Proof

在分析几种典型零知识身份认证协议的基础上,利用Girault自证明公钥原理、结合椭圆曲线公钥密码的优点提出一种基于自证明公钥和零知识证明的身份认证协议,并为协议增加了密钥协商功能。分析表明该方案具有较高的安全性,与同类方案相比,该方案对存储空间、网络通信量和计算开销的要求较低,有较高的效率。

Based on the analysis of several typical zero-knowledge proof authentication protocols, this paper presents an authentication protocol with key-exchange function based on self-certified public key and zero-knowledge proof, which combines Girault＇s self-certified public key theory and the advantages of ECC. Analysis show that the scheme has higher security. Compared with the congeneric schemes, the proposed scheme is more efficient and has advantages in storage, communication overheads and computation cost.
