Abstract

Abstract:

Presents a new group of group-signature scheme based on discrete logarithm,called(t _j,t,n)threshold group-signature scheme.Comparing to a normal group-signature scheme,these new schemes have two advantages:(1)Each member can have different power;(2)Can set parameter skillful and get different schemes for different utilizations.Also demonstrate the security of these schemes.

Key words: digital signature, (t_j t n)threshold group signature, scheme pre-signature personal, signature group, signature, discrete logarithm
