摘要 利用椭圆曲线上的双线性对,首次构建了一个基于属性的指定证实人签名方案.在该方案中,具有指定属性的人均可对签名的有效性进行确认.同时,对方案的正确性和安全性进行了分析.分析表明本方案具有不可伪造性,并能抵抗合谋攻击. In this paper , we propose a designated confirmer signatures scheme based on bilinear pairings , in which both the signer and the designated confirmer , who has the specific attributes , can confirm a valid desig-nated confirmer signatures .Finally we analyze its correctness and security .Analysis results show that this scheme obtains the advantages of unforgeability and can resist conspiracy attack ..
