A New ID-Based Threshold Group Signature Scheme
Zhiqiang Zhang, Yunlong Ye · 2012
A (t,n) threshold group signature scheme allows a singer to determine a (t,n) threshold strategy and only t or more signers of the group can sign messages on behalf of the group. In this paper, we proposed a new ID-based threshold group signature scheme based on discrete logarithm problem, which not only satisfies all the secure requirements but also can resist repeated attack and conspriacy attack.
