一种椭圆曲线群签名方案的设计与分析

Design and Analysis on the Elliptic Curve Group Signature Scheme

群签名在设计上比较复杂,目前的方案基本都是基于离散对数或者知识签名的,签名长度都比较长,因此只有提高群签名的效率,才能使它真正的得到广泛应用。椭圆曲线密码体制在于在安全性相当的前提下,可使用较短的密钥和较小的空间,论文设计了一个基于椭圆曲线数字签名的群签名方案。

Design of the group signature is complex,the current scheme are based on signature knowledge or discrete logarithm,the length of the signature is very longer,so,improving the efficiency of group signatures can really be widely applied.Elliptic curve cryptosystem is rather in the premise of security,you can use shorter keys and smaller space,this paper design a digital signature based on elliptic curve group signature scheme.
