摘　　要：代理签名是解决签名权利委托的一种方案,代理签名可以结合其他特殊的签名方案生成一些新的代理签名方案.代理多重签名可以解决一个签名人代替多个原始签名人签名的问题,盲签名用于隐藏原始消息.结合代理多重签名和盲签名的特性,从双线性对的角度提出一种基于身份的代理多重盲签名方案,私钥生成器利用每个签名人本人身份生成不同的密钥.通过对方案的安全性分析,发现该方案可以抵抗原始签名者内部攻击,防止代理签名权的滥用,具有不可伪造性、不可否认性、不可链接性、盲性和计算效率高的特点.Proxy signature is a solution to the delegation of signature rights.Proxy signature could combine with other special signature schemes to generate some new proxy signature schemes.Proxy multi-signature could solve the problem of one signer signing instead of multiple original signers,and blind signature is used to hide the original message.Combining the characteristics of proxy multi-signature and blind signature,an identity-based proxy multiple blind signature scheme was proposed from the perspective of bilinear pairing.The private key generator use each signer′s identity to generate different keys.Through the security analysis of the scheme,it was found that the scheme could resist the internal attacks of the original signer and prevent the abuse of proxy signature rights.It had the characteristics of unforgeability,nonrepudiation,nonlinkability,blindness and high computing efficiency.
