摘 要: 提出了一个动态门限群签名方案 .此方案不仅能满足门限群签名的性质 ,而且与已存在的门限群签名方案相比 ,具有以下优点 :( 1)能方便更改门限值 ;( 2 )能抵抗合谋攻击 ;( 3 )方便加入或注销群成员 。 A dynamic threshold group signature scheme is proposed in this paper. Comparing to the existing threshold group schemes, the scheme not only can satisfy the properties of threshold group signature, but also has following advantages: conveniently change threshold value, withstand conspiracy attack, conveniently add or delete one or more the group members, and the scheme's parameters are changed little.
