| 摘 要： | 现有基于身份的盲签名方案安全性依赖于可信私钥产生机构，结合受限部分盲签名和门限性质，利用双线性对实现一种新的基于身份的部分盲签名方案。分析结果表明，与同类签名方案相比，该方案在保持高效性的同时，具有更多安全特性，其整体安全性较高。

| Abstract: | Aiming at the problem of current ID-based blind signature scheme that its security is based on the trusted Private Key Generator(PKG), this paper realizes an ID-based partially blind signature scheme by using bilinear pairing. The scheme combines restrictive partial blind signature and threshold properties. Analysis results show that compared with the related research, this scheme maintains efficiency while ensuring higher security and bringing in more security properties. |
