摘　　要：数字签名是密码学的研究热点之一,在信息安全领域发挥着越来越重要的作用,不论是电子政务还是区块链技术都需要数字签名技术的支撑。代理盲签名作为一种特殊的数字签名体制,是近年来数字签名研究的热点问题。但是随着量子计算机前沿发展迅速,传统公钥密码体制下的代理盲签名方案已不能很好地满足当下应用环境的需求,因此基于多变量公钥密码体制设计安全可行的代理盲签名方案在抵抗量子计算机攻击方面具有重要的现实意义。本文基于多变量公钥密码体制研究热点之一的Rainbow体制,设计了一个代理盲签名方案,然后对其进行了安全性分析的同时与传统密码体制签名进行对比分析,分析结果表明其在确保安全性的同时又满足代理盲签名相关特性,为代理盲签名提供了一种更适应当前应用需求的方案。Digital signature is a research focus of cryptography and plays an increasingly important role in the field of information security,providing technical support to both the e-government and blockchain technology.As a special digital signature system,proxy blind signature is a hot issue of digital signature in recent years.However,with the rapid development of quantum computer,the proxy blind signature scheme in traditional public key cryptosystem could not satisfy the current requirement for application environment.Thus,designing a safety and feasible proxy blind signature scheme based on multivariate public key cryptosystem has great practical significance to resist quantum computer attacks.Based on the Rainbow algorithm that is a research focus of multivariate public key cryptosystem,a proxy blind signature scheme is proposed in this paper.Then,the security of the proposed scheme is analyzed and the performance of the proposed scheme is compared with the traditional cryptography signature.Analysis results indicate that the proposed scheme ensures the security as well as satisfies the related properties of the proxy blind signature,and the proposed scheme provides a solution with wider application prospect to the proxy blind signature.
