摘要:已提出的代理重签名方案都不具备消息致盲性,因此在保护原始签名者隐私方面存在缺陷。该文把一般的
代理重签名方案进行扩展,借鉴盲签名的设计思想,首先给出盲代理重签名方案的定义;根据该定义,运用双线性
映射的技术以及 Waters 提出的标准模型签名的框架,提出了一种基于标准模型的盲代理重签名方案,并证明了该
方案的安全性。该方案实现了签名从原始签名者到代理重签名者之间的透明转换,保护了原始签名者的隐私;同时,
由于方案设计过程中采用了标准模型的框架,具有一定的实用性。

Abstract: The proposed proxy re-signature schemes had no message blinded properties as yet, so there is a problem
that they can not protect the original signer’s privacy. The general proxy re-signature scheme is extended using the
idea of blind signature. The definition of blind proxy re-signature scheme been given firstly; then according to the
definition, the blind proxy re-signatures scheme Based on Standard Model is proposed using of bilinear mapping
technology and standard model framework proposed by Waters, finally, the security of the scheme is proven. The
transparent signature conversion from o
