摘　　要：知识签名就是签名者在非交互的情况下向别人证明其知道某个秘密而不泄露该秘密本身,现在知识签名广泛应用在群签名中.本文主要研究了带系数的离散对数知识签名,并对几种类型的带系数签名函数进行了定义和证明.通过对签名函数增加系数,可以有效地扩大签名函数的选择范围,增加知识签名的适用性.Signature of knowledge is that signer can prove that he knows knowledge of a secret with respect to public informarion noninteracdvely and he don＇ t leak any secret message. Signature of knowledge has been used in many group signature schemes.In this paper,we mainly study on signature functions of knowledge with coefficient, and give out definition and proof of several kinds of signatures of knowledge of discrete logarithm with coefficient. The coefficient can increase the choices of signature functions,make signatures of knowledge more available.
