一个有效的门限群签名方案

An Efficient Threshold Group Signature Scheme

门限群签名是一种重要的数字签名.但现有的门限群签名方案几乎都存在无法抵御合谋攻击的缺陷.本文提出一个新的门限群签名方案,方案满足门限群签名应具有的性质,并能够抵御部分成员的合谋攻击,具有强壮性和防伪造性。

Threshold group signature is an important kind of digital signature. But almost all the proposed threshold group signature scheme can not resist the collusive attack. This paper proposes a new threshold group signature scheme which has the properties of threshold group signature and can resist the collusive attack.
