摘　　要：证实数字签名是在不可否认数字签名的基础上提出的一种新的具有特殊用途的数字签名方案。在分析已有证实数字签名算法缺陷的基础上,将零知识证明引入证实数字签名,提出了一个改进的证实数字签名方案。方案中签名者不直接提供对信息的签名,而是提供一个零知识证明其拥有对该信息的数字签名,该证明中含有签名者的身份信息。改进的方案比传统的证实数字签名算法简单有效,且具有较高的安全性。An improved confirmer digital signature scheme was presented based on the analysis of the disadvantages of traditional confirmer signature algorithm and the introduction of zero-knowledge proof. In this scheme, signer need not directly provide his signature to the information, he just need to provide a zero-knowledge to prove that he has the information signature. This zero-knowledge proof includes the signer＇s identity information. Compared with the traditional confirmer signature algorithms, the improved scheme is simpler and more efficient, and has higher security.
