摘要 现有的门限签名方案存在大量动态的用户集合,不适用于移动Ad-hoc网络(MANETs)。为此,提出一种适用于MANETs网络的高效门限签名协议。该协议的安全性基于标准RSA假设,且满足通用可组合安全性。高效门限签名协议具有前摄性,能够同时提供"分享密钥"和"更新用户子密钥"的功能。安全性分析结果证明该协议的高效性。 Threshold signature methods mostly have very large and dynamic groups,they don't apply to Mobile Ad-hoc Networks(MANETs).This paper presents an efficient threshold signature protocol for MANETs,which is proved secure based on the basic RSA assumption,and satisfies universal compsability security.Furthermore,the proposed protocol is proactive,providing both the "the secret key sharing" and "the partial secret key refreshing".Security analysis result proves the high effectiveness of the protocal.
