摘要 针对零知识身份认证协议存在的问题,根据数字水印能隐藏信息的特点,提出了一种新的零知识身份认证协议。在此协议中使用数字水印改善了认证的特性。在认证过程中,验证者在验证示证者身份时需要两方面的信息:一是来自网络的信息,二是本地的信息,从而有效地解决了存在的问题,提高了认证的安全性。 In order to answer the problems in Zero-knowledge authentication, proposed a new authentication scheme, in which used watermark to promote the characters of authentication. In the authentication scheme, the verifier verifies the identity of user depending not only on the information coming from network, also on local information. The new authentication answers the problems.
