摘要

在Kim-like代理多重签名方案的基础上

提出一个改进的代理多重签名方案

它解决原方案存在的两个问题:(1)安全性

任意一个原始签名者能伪造代理多重签名.(2)效率

代理多重签名的长度和验证其签名效率与原始签名者的个数有关.

Abstract

On the basis of the Kim-like's proxy multi-signature scheme

we propose an improved proxy multi-signature scheme

which resolves two problems in the Kim-like's proxy multi-signature scheme:(1)Security

anyone of the multi-original signers can forge a valid proxy multi-signature for any message.(2)Efficiency

the size of the proxy multi-signature and the efficiency of checking whether it is avail are dependent on the number of the original signers.
