Threshold Group-signature Scheme Based on Discrete Logarithms and Factoring
Qi You Xie · Science Technology and Engineer · 2003
A new group-signature scheme is given, which is based on discrete logarithm and factoring, called ( t_j, t, n ) threshold group-signature scheme. Comparing to a general group-signature scheme, these new schemes have two advantages: (1) Each member can have different power; (2) One can set parameter skillful and get different schemes for different utilizations. The security of these schemes is discussed.
