基于身份的可认证盲签名协议

The Identity-Based Authenticated Blind Signature Protocol

提出了一个基于椭圆曲线双射对性质实现的、基于身份的具有可相互认证功能的盲签名协议.该协议把对用户身份的认证和对机构的认证融合到一个盲签名协议中,不仅避免了盲签名应用系统中对用户身份的额外认证,还使得应用系统的整体工作效率大大提高,有效地避免了盲签名系统在实际应用中同其他认证系统协同工作时可能出现的一些潜在的不安全问题.协议具有强不可伪造性和强不可否认性.

This paper proposed an identity-based authenticated blind signature protocol using the bilinear pairing property based on elliptic. The proposed protocol combines the authenticated functions for users with a blind signature protocol, which not only avoids the extra authentications for users in the system that uses the blind signature, but also improves the work efficiency of the system much, and efficiently avoids some potential insecure problems when a blind signature scheme cooperates with another authenticated system in a real application. The proposed protocol provides strong non-forgeability and strong non-deniability.
