The plug-in has three advantages: First, each packet is authenticated by a One-time Signature, so there is no need for both sender and receiver maintain a buffer and there is no delay for signing and verifying and authentication failure of current packets do not effect the authentication of other packet. Second, we design a mechanism to regenerate Merkle Trees, so just only one normal digital signature signing operation is required to provide unlimited number of One-time Signature for signing unlimited length of

插件有如下特点:一、使用一次签名对每个包单独签名和认证,接发双方不需要缓存包,没有延迟,而且当前包的认证失败或者丢失不影响其他包的认证;二、设计了两颗树交替更新的机制,只需要开头一个普通数字签名,就能确保有效的一次签名能源源不断的生成,因此可对无限长的流签名;三、在包的层次上操作,因此可以处理任何流媒体类型。

Based on characteristic of chinese handwritten signature, some programs are developed to acquire the dynamic handwritten signature data from WACOM Tablet and to calculate velocities from acquired dynamic data. Based on statistics theory, instantaneous velocity and average X velocity and average Y velocity and time when the first maximal velocity arriving during on-line handwritten signa...

根据汉字手写签名的特点,编程从手写板获取签名的动态数据,编写了提取手写签名多种速度特征值的程序,在统计的基础上,对手写签名过程中的瞬时速度、X轴向平均速度和Y轴向平均速度、最大速度出现的位置、极大速度首次出现的位置等特征量的稳定性进行了实验研究,得出了一些有用的结论。

In this dissertation, two new proxy signature schemes from bilinear pairing are proposed, which are all based on discrete logarithm problem on GDH group. In the first scheme, the proxy signing ability can be revoked during the period of validity. Then, the malicious signer can not sign messages any more. Moreover, in this scheme secure channels are not needed.

本文基于GDH群的离散对数问题结合短签名的特点设计了两个代理签名体制,第一个体制可以在证书的有效期内撤销代理签名权,从而防止不诚实的代理签名者继续签名,而且无需安全信道。

This paper designs a new fuzzy signature scheme based on the discrete algorithm problem.

As the extension of restrictive blind signature, partially restrictive blind signature allows some public information to be included in the signature while the anonymity and exposure ability against double signer of receiver are still hold.

部分受限盲签名是受限盲签名的扩展,使用该技术可以在实现接收者的匿名性和重复签名可揭示性的同时,将某些公共消息编码到签名中。

The law of electronic signature prescribed the force efficacity of the trustingly electronic signature,the responsibility and the charge in offence of electronic signaturer and electronic signature appraise,but did not involved how to quote correlative electronic signature.

电子签名法对可靠电子签名的法律效力、电子签名人与认证者的责任及过错承担做了原则规定,但对相关电子签名如何举证、签名依赖方等相关方的过错责任及各方无过错后果如何承担,出现损失后如何能确保相关方的合法权益得到补偿等没有涉及,通过对上述问题的探讨以期对具体的司法实践掌握有所裨益。

The scheme shows that the new scheme is an implementation of secure and efficient confirmer signature.

在证实数字签名方案中,签名的证实和否认功能由一个半可信任的第3方承担,同时证实者具有转化一个证实数字签名为一个普通数字签名的能力。当然,签名者不能参与证实的过程,证实者也不能参与签名的过

The scheme not only expands the function of undeniable digital signature by verifying a signature without exposing any knowledge,but also improves confirmer digital signature due to its much more simplicity than the latter in practice and the significant feature is that it does not need the participation of the third party.

数字签名已经广泛使用于电子商务及网络安全中。数字签名可用来保护信息产品的版权,但普通的数字签名很容易被复制,为了防止数字签名的传播,Chaum[3 ] 引进了不可否认数字签名

First of all, this thesis points out that Qian-Cao-Xue\'s scheme (the first threshold proxy signature scheme from bilinear pairings) does not possess the property of strong unforgeability, presents two attacks and proposes an improved scheme which can resolve the security problem existing in their scheme.

本文主要研究了面向群体的数字签名中的代理数字签名、群数字签名及其应用,对一些数字签名的安全性进行了分析,设计了一些具有附加功能的数字签名

Electric seal is a method to sign a document and it is a kind of electric signature, though a document has some difference compare to other kind of data like program, data of a database, according the speciality of a electric signature to a document, such as view what we signed , validate the signature in a document directly, how to archives a document which has been signed, how to read a document has been archived, it points out that a document is exactly some data with some format data, a document could be disparted as two parts, data and format data.

电子印章是应用层的数字签名,是电子签章的一种,由于文档签名与其他类型数据如程序,数据库数据等相比有其特殊性,本文针对文档签名的特殊性,如签名的可见与可证实性,文档的归档特性,文档阅读的方便性等进行了分析,指出文档实际上是一种格式化的数据,可以分为数据与格式两个部分,在此基础上提出了对文档进行签名的要求。
