摘要:

基于离散对数问题给出了一类新型 (tj,t,n)门限群签名方案,该类群签名方案与一般的群签名方案相比具有如下特点 :(1 )各签名者可具有不同的权力 ;(2 )可通过灵活设置参数得到满足不同应用需求的解决方案.同时还对这类方案的安全性进行了安全论证

关键词: 数字签名, (tj, t, n)门限群签名, 预签名, 个人签名, 群签名, 离散对数

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, (tj t n)threshold group signature, scheme pre-signature personal, signature group, signature, discrete logarithm
