摘要: 为了克服基于身份部分盲签名方案的安全性依赖强和签名验证计算开销大等缺陷,结合基于身份的部分盲签名和服务器辅助验证签名,提出了基于身份的服务器辅助验证部分盲签名体制,将签名验证的大部分计算任务委托服务器执行,有效减少了验证者的计算开销。利用双线性映射,设计了一个具体的基于身份服务器辅助验证部分盲签名方案,并在标准模型下证明所提方案是安全的。分析结果表明,所提方案大幅降低了签名验证算法的计算复杂度,在效率上优于Li方案(LI F,ZHANG M,TAKAGI T.Identity-based partially blind signature in the standard model for electronic cash.Mathematical and Computer Modelling,2013,58(1):196-203)和Zhang方案(ZHANG J,SUN Z.An ID-based server-aided verification short signature scheme avoid key escrow.Journal of Information Science and Engineering,2013,29(3):459-473)。

Abstract: Combined ID-based partially blind signature and server-aided verification signature, a partially blind signature scheme with ID-based server-aided verification was presented to overcome the shortcomings of ID-based partially blind signature schemes such as strong security assumption and high computation cost. Most computing tasks of signature verification were accomplished by a server, and it greatly reduced computational overhead of verifier. Based on bilinear mapping, a partially blind signature scheme with specific ID-based server-aided verification was proposed. This scheme was proven to be secure in the standard model. Analysis results show that the proposed scheme greatly reduces computational complexity of signature verification. The proposed scheme is more efficient than Li's scheme (LI F, ZHANG M, TAKAGI T. Identity-based partially blind signature in the standard model for electronic cash. Mathematical and Computer Modelling, 2013, 58(1):196-203) and Zhang's scheme (ZHANG J, SUN Z. An ID-based server-aided verification short signature scheme avoid key escrow. Journal of Information Science and Engineering, 2013, 29(3):459-473).
