Then,based on IBS,we propose two ID-based blind signatures called BIBS1 and BIBS2, respectively, and prove their security from blindness and unforgeability in the random oracle model.

首先设计了一种基于ID的签名方案IBS，然后在此基础上设计了两种基于ID的盲签名方案，称为BIBS1和BIBS2；在随机预言模型中证明了它们的盲性和不可伪造性。

In this paper, the first identity-based proxy signature scheme without random oracles is proposed based on Paterson, et al's identity-based signature scheme. The unforgeability of the proposed scheme is based on the hardness of the well known computational Diffie-Hellman problem.

利用Paterson等的基于身份的签名方案构造了一个基于身份的代理签名方案，并在标准模型下基于计算Diffie-Hellman假设证明了它的安全性。

Aggregate signature and its applications on constructing verifiably encrypted signature scheme are studied.

研究了聚集签名技术及其应用于可验证加密签名体制的构建方法。

Based on the verifiably encrypted signature scheme without random oracles recently proposed by Gorantla et al.,a new scheme of optimistic fair exchange of digital signatures is proposed in this paper.

基于Gorantla等最近提出的标准模型下可证安全的可验证加密签名，提出了一个优化的公平数字签名交换方案。

An Identity-based verifiably encrypted signature scheme using bilinear pairings on ellipse curve was constructed, and a new fair multi-party exchange protocol was designed.

利用椭圆曲线上的双线性对构造基于身份的可验证加密签名方案，基于这种签名方案构建了一种新的多方公平交换协议。

The novel scheme employs verifiably encrypted RSA signatures in the extended integer ring that is elaborately constructed. The security and efficiency of the newly devised scheme are also proved and examined.

在此基础上，利用精心构造的扩环中可公开验证的、加密的RSA签名，提出了一种完全基于RSA签名方案的优化公平交换协议，并对其安全性和效率进行了证明和分析。
