基于零知识证明的匿名身份认证机制

Anonymous Authentication Mechanisms Based on Zero-knowledge Proof

近年来,随着互联网的快速发展,匿名身份认证对保护用户的隐私和信息安全发挥着越来越重要的作用。对现有身份认证机制进行了分析,指出其存在的缺点,并在此基础上,提出了改进方法,给出了基于Wang的使用数字签名的零知识证明的匿名身份认证方案。该方案既降低了通信流量,又具有更高级别的安全性。

With the rapid development of Internet,anonymous authentication plays more and more important roles dur- ing the users＇ privacy protection and information security. Based on the analysis of existed authentication scheme, this paper pointed out the existing shortcomings and proposed the improved one. In addition, the paper gave the zero-know- ledge proof of the scheme with digital signatures proposed by Wang. The proposed scheme greatly reduces the traffic and increases the security.
