一类高效的无证书代理盲签名方案

已有的代理盲签名方案主要是基于传统公钥密码系统(PKI)以及基于身份的公钥密码系统(ID-PKC)提出的,它们分别存在看证书存储、管理以及密钥托管等问题.为避免上述问题,在无证书公钥密码系统上利用双线性对的知识提出了一种高效的无证书代理盲签名方案,该方案不仅具有较高的效率,满足代理盲签名要求的所有性质,而且克服了它们所...

An Efficient Certificateless Proxy Blind Signature Scheme

Until now the existing proxy blind signature schemes are mainly based on certificate-based public key cryptography or identity-based cryptography,which have the problems of certificate management and key escrow respectively.To resolve the problems above,we proposed a new certificateless proxy blind signature scheme from bilinear pairings in the certificateless public key cryptography.It is proved that our scheme satisfies all the requirements of proxy blind signatures.Furthermore,our scheme is more efficien...
