IMPROVEMENT OF NONREPUDIABLE THRESHOLD MULTI-PROXY THRESHOLD MULTI-SIGNATURE SCHEME WITH SHARED VERIFICATION被引量:2
《Journal of Electronics(China)》2007年第6期806-811,共6页Xie Qi Wang Jilin Yu Xiuyuan 
Supported by the National Natural Science Foundation of China (No.10671051);the Natural Science Foundation of Zhejiang Province (No.Y105067).
In 2005, Bao, et al. [Appl. Math. and Comput., vol.169, No.2, 2005] showed that Tzeng, et al.’s nonrepudiable threshold multi-proxy multi-signature scheme with shared verification was insecure, and proposed an improv...

Attack on Digital Multi-Signature Scheme Based on Elliptic Curve Cryptosystem被引量:2
《Journal of Computer Science & Technology》2007年第1期92-94,共3页刘铎 罗平 戴一奇 
This work is supported by the National Natural Science Foundation of China under Grant No. 90304014 and the National Grand Fundamental Research 973 Program of China under Grant No. 2003CB314805.
The concept of multisignature, in which multiple signers can cooperate to sign the same message and any verifier can verify the validity of the multi-signature, was first introduced by Itakura and Nakamura. Several mu...

A NEW THRESHOLD MULTI-PROXY MULTI-SIGNATURE SCHEME被引量:3
《Journal of Electronics(China)》2006年第4期560-563,共4页Kang Baoyuan Han Jingguang Wang Qinju 
Supported by the National Natural Science Foundation of China (No.10471152).
This paper proposes a threshold mult-proxy multi-signature scheme with share verification. In the scheme, a subset of original signers allows a designated group of proxy signers to sign on behalf of the original group...
