在身份公钥密码体制下,结合盲签名,提出了一个高效的基于身份的盲签名方案。详细地分析了方案的安全性,得出该方案具有不可伪造性、盲性和不可追踪性等安全性。与已有方案相比,该方案具有更少的双线性对运算量,计算效率较高。
This paper proposes an efficient identity-based blind signature scheme based on identity-based public key cryptogra-phy by adopting blind signature scheme.By analyzing the schemei,t concludes that the scheme has unforgeability,blindness,un-traceability.Compared with other schemest,he new scheme has lower computation complexity and better computational efficiency.
