摘要:

针对盲代理重签名的匿名性和可控性问题,借鉴部分盲签名的设计思想,引入部分盲代理重签名的概念,并给出了部分盲代理重签名的安全性定义。基于改进的 Shao 方案,构造一种标准模型下的双向盲代理重签名方案,允许在最终的重签名中添加受托者和代理者协商的公共信息,不仅实现了签名从受托者到代理者之间的透明转换,保护重签名消息的隐私,还能防止受托者对重签名的非法使用。分析结果表明,新方案满足正确性、多用性、部分盲性和不可伪造性,其性能更适用于电子政务数据交换、跨域身份认证等系统。

Abstract:

In order to solve the problem of anonymity and controllability of blind proxy re-signature,the concept of partially blind proxy re-signature was introduced by using the idea of partially blind signature.Furthermore,the security definition of partially blind proxy re-signature was also given.Based on the improved Shao scheme,a partially blind proxy re-signature scheme in the standard model was proposed.The proposed scheme allows proxy to add some public information negotiated by delegatee and proxy to re-signature.The scheme not only can achieve the transparent signature conversion from delegatee to proxy and protect privacy of message re-signed by proxy,but also prevented illegal use of re-signature.Analysis results show that the proposed scheme is correct,multi-use,partially blind and existentially unforgeable.It is more suitable for e-government data exchange system,cross-domain authentication system and so on.

Key words: partially blind proxy re-signature, unforgeability, multi-use, standard model
