知识签名

Signatures of Knowledge

知识签名就是签名者利用数学知识和公共信息,非交互和不泄露某个秘密的情况下向别人证明他知道这个秘密。现在知识签名广泛应用在群签名中,利用它可以在签名中有效减少交互次数,提高签名速度。本文主要研究了带有系数的离散对数知识签名。

Signature of knowledge is that signer can prove that he has knowledge of a secret with respect to public information noninteractively and he doesn＇t leak any secret message. Signature of knowledge has been used in many group signature schemes. It can improve speed of the signature by decreasing interactive times during signing when we make use of signatures of knowledge. In this paper, we mainly study signatures of knowledge of discrete logarithm with coefficient.
