Proactive Threshold Signature Protocol for MANETs
Zhongmei Wan · Jisuanji gongcheng · 2012
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 basic RSA assumption,and satisfies universal compsability security.Furthermore,the proposed protocol is proactive,providing both the secret key sharing and the partial secret key refreshing.Security analysis result proves high effectiveness of protocal.
