摘要

1998年

Lee 和Chang提出了一种基于离散对数问题的群签名方案。Tseng 和Jan

敖等[3]分别在此基础上给出了新的改进方案。本文对Tseng-Jan方案[2]Ⅱ和敖等[3]的方案进行了分析

通过构造伪造签名

指出这两种方案存在着安全漏洞。

Abstract

In 1998

Lee and Chang proposed a group signature scheme based on the discrete logarithm problem.Tseng

Jan and Ao gave respectively new improved scheme based on Lee-Chang scheme. In this paper

we show there are still some security leaks in these schemes

and give some methods of forgery attack.
