文章提出了基于双线性的前向安全的门限部分盲签名方案，该方案利用更新门限成员中的部分私钥来保证前向安全的基础，结合门限签名和部分盲签名性质，不但增强了签名消息的安全性，同时简化了签名中心在签名过程中的作用。由于前向安全的特点，方案可以防止移动攻击，安全性分析表明方案具有部分盲性、不可伪造性和前向安全性。

A forward secure threshold partially blind signature scheme based on bilinear pairing is pro-posed .The scheme uses the update of the members’ private key to ensure the forward security .The new scheme takes into consideration the nature of the threshold signature and partially blind signa-ture ,w hich enhances the security of the signature message and simplifies the signature center ’s role in the signing process .Because of the characteristics of forward security ,the scheme can prevent the mobile attack .The results of security analysis show that the scheme has partial blindness ,unforge-ability and forward security .
