盲签名和代理多重签名在电子商务和电子现金系统中有着广泛的应用。文章通过对代理盲多重签名方案安全性的分析,发现方案中一个恶意的原始签名人可以伪造出代理签名密钥,从而可以生成代理盲多重签名,在此基础上提出了基于双线性配对的代理盲多重签名方案,克服了原方案的缺陷,并提高了签名效率。
盲籤名和代理多重籤名在電子商務和電子現金繫統中有著廣汎的應用。文章通過對代理盲多重籤名方案安全性的分析,髮現方案中一箇噁意的原始籤名人可以偽造齣代理籤名密鑰,從而可以生成代理盲多重籤名,在此基礎上提齣瞭基于雙線性配對的代理盲多重籤名方案,剋服瞭原方案的缺陷,併提高瞭籤名效率。

Blind signature and proxy multi-signature are widely used in e-commerce and e-cash systems . The security analysis of a certain proxy blind multi-signature scheme is carried out .It is found that this scheme can not resist the proxy signing key forgery attack from a malicious original signer w ho u-ses the forged proxy signing key to generate the proxy blind multi-signature .In order to resist the a-bove forgery attack ,a novel proxy blind multi-signature scheme based on bilinear pairings is pro-posed ,w hich is proved to be much more correct and safer than the former scheme .
