基于身份的盲签名方案设计

ID-based Blind Signature Schemes Design

利用椭圆曲线上Weil配对的双线性性质,提出了基于身份的盲消息、盲参数和弱盲等3种签名方案.这些方案用以身份为基础的公钥取代数字证书形式的公钥,有效地省略了验证签名时从系统中获取公钥的步骤,减少了交互的次数并节省了存储空间.

The blind signature schemes of ID-based blind message, blind parameter and weak blindness by using the bilinear property of Weil pairing defined on elliptic curve are proposed. These schemes use ID-based public key to replace the digital certification public key and can effectively omit the process to get public key from the system in signature verifying phase. With the schemes the interaction times and the memory space can be reduced.
