Considering RSA is one of the most widely used cryptosystems,this paper proposes a confirmer signature scheme based on RSA for the first time.

考虑到RSA是应用最广泛的公钥密码体制之一，该文提出了一种完全基于RSA的证实数字签名方案，分析表明，该方案是一种安全高效的证实数字签名实现方案。1概述Chaum引进了证实数字签名[3]的概念。

An improved confirmer digital signature scheme was presented based on the analysis of the disadvantages of traditional confirmer signature algorithm and the introduction of zeroknowledge proof.

证实数字签名是在不可否认数字签名的基础上提出的一种新的具有特殊用途的数字签名方案。

Furthermore, if it is necessary, the confirmer could convert confirmer signatures into standard ones such that the validity of these converted signatures can be publicly validated.

进一步地，在必要的时候，证实者还可以将证实签名转化为普通的数字签名，从而使得任何人都可以验证这些签名的有效性。

According to real-time requirement of stream data and losable characteristic of transportation, the thesis analysis existing stream data signature methods suc h as star-s haped tree-shaped and Golle chain. Considering the condition of limit ed resource of receiver, it proposes forward plac ed hash chain data signature sc h eme based on Gilbert-Elliot Network channel model and enhanc ed Golle chain stream data signature method.

本文针对流式数据实时性要求和传输中易丢包的特点，分析比较了现存的星型、树型、Golle链型等几种典型的流式数据签名方法，考虑到接收方资源有限的情况，基于Gilbert-Elliot网络通道模型，改进了Golle链型流式数据签名方法，提出了一种hash值前置流式数据签名方案。

A negotiable document having enhanced security for deterring the generation of counterfeit photocopies of the negotiable document, said negotiable document comprising: a front face; a signature area located on the front face; a first pantographic background design creating a seemingly random background covering a first area of the negotiable document; and a second pantographic design creating a seemingly random background covering the signature area of the negotiable document; and a warning clause, located in the signature area, having a background and print that is visible prior to and after any photocopying of the negotiable document and describing the second pantographic design of the signature area.

可协商文档由于加强了安全性可以防止产生影印的赝品可协商文档。这种可协商文档通常由一个封面，封面上的签名区，一个覆盖可协商文档首部的可缩放的背景设计产生一个表面上随机的背景和一个位于签名区的警告条款，这一条款的背景对于影印的可协商文档是可见的并且在影印文档的前面描绘签名区的第二种缩放设计。

Signature dynamics. Based on an individual's signature, but considered unforgeable because what is recorded isn't the final image but how it is produced——i.e., differences in pressure and writing speed at various points in the signature.

签名动力学它是基于一个人的签名，但被认为是不可伪造的，因为它所记录的不是最后的图像，而是如何产生图像，即在签名的各个点上的压力和书写速度是不同的。
