多重代理盲签名是代理盲签名的延伸,被授权的代理签名者代替多个原始签名者进行签名.采用构造方法,分析一个不需要安全渠道的多重代理盲签名方案的安全性,结果证明其不安全,不满足不可伪造性和不可链接性,不能用于电子商务、电子货币、电子投票等系统.
多重代理盲籤名是代理盲籤名的延伸,被授權的代理籤名者代替多箇原始籤名者進行籤名.採用構造方法,分析一箇不需要安全渠道的多重代理盲籤名方案的安全性,結果證明其不安全,不滿足不可偽造性和不可鏈接性,不能用于電子商務、電子貨幣、電子投票等繫統.

A multi-proxy blind signature is an extension of proxy blind signature, which allows the designated proxy signer to generate a signature on behalf of several original signers. The security of a proxy blind multi-signature scheme without a secure channel is analyzed with the method of construction. The results show that this proxy blind signature scheme is not secure. The scheme does not satisfy the properties of unforgeability and unlinkbility. It can not be applied to e-commerce, e-cash and e-voting system.
