摘　　要：一个基于DSA和RSA的证实数字签名方案(WWZ)存在“非零知识性”、“弱不可见性”和“可转移性”安全性缺陷,该方案中作为证实数字签名核心部分的确认与否认协议是不安全的.为此,提出了一种改进的确认与否认协议,改进的协议实现了“零知识证明”和“不可见性”,实现了WWZ方案的安全和有效.There is a drawback of security in the confirmer signature scheme WWZ based on DSA and RSA. It includes non - zero knowledge, weak non - visibility and transferability. The kernel protocol of confirmation and disavowal in the scheme WWZ is not safe. After researching on the drawback of security in the protocol, an improved protocol of confirmation and disavowal is put forward in this paper. The attestations of zero knowledge and non - visibility have been realized in the improved protocol, and then the scheme WWZ will be secure and efficient.
