一种零知识证明的群签名方案

在群签名方案中,群中任意成员可以代表整个群生成签名,在验证者仅需要知道签名的存在性时,群管理员必须参加验证,群签名通过群公钥公开验证。论文提出了一种可用零知识证明的群签名方案,签名者不直接提供对信息m的签名,而是提供一个零知识证明他或她拥有对该信息的数字签名,这对防止签名的任意传播起到了很好的保护作用。

A Group Signature Scheme of Possessing Zero-Knowledge Proof

In the schemes of the group signature,any individuals can sign a signature for the group.If the inspector only need know the existence of the signature,the administrator must be in for validation.The group signature is proved to be right by the validation of public key.We have proposed a scheme of the group signature that can be proved by zero-knowledge.A signatory don't need to give directly the signature of the message,but only give a zero-knowledge proof of possessing the signature.The zero-knowledge is a new method of preventing arbitrary propagation of signature.
