A digital signature scheme is analogous to the traditional handwriting signature. Since it achieves unforgeability, integrity and non-repudiation, digital signature plays an important role in E-commerce and E-government.

数字签名是对传统手写签名的模拟，它具有防伪造、防篡改和防抵赖等特点，在电子商务和电子政务中有重要应用。

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。

The security of the Fu-Kou-Xiao's proxy signature scheme with proxy signer's privacy anonymity was analyzed, and it was shown that the scheme did not possess the property of strong unforgeability.

对 Fu-Kou-Xiao 具有代理匿名性的代理签名方案进行分析，指出该方案不具备强不可伪造性。

Aiming at the actual need of impeach work, and on the basis of analyzing, concluding, summarizing and informing against the systematic current situation at present, the article structure the new model of electronic impeaching system, adopt group signature and bit commitment technology to realize each functions of the system respectively, and guarantee the security of accuser, such as anonymity, unforgeability, undeniable, unlinkability,traceability,etc.

论文针对检举工作的实际需要，在分析、归纳、总结了当前检举系统现状的基础上，构造了新型电子检举系统的模型，并分别采用群签名和比特承诺技术实现了系统的各项功能，保证了匿名性、不可伪造性、不可否认性、不相关性和可追踪性等安全性。

S scheme which is a combination of Mambo et al.\'s proxy signature scheme and Zheng\'s signcryption scheme. Our analysis demonstrates that their scheme cannot guarantee strong unforgeability, strong identifiability, non-repudiation, and prevention of misuse.

他们的体制本质上是Mambo等人的代理签名体制和Zheng的签密体制的结合，安全性分析表明他们的体制不能满足强不可伪造性、强可识别性、不可抵赖性，也不能防止滥用。

In the random oracle model,it can be proved that the new protocol fulfills all the characteristics that anonymous subscription protocols should satisfy in order to be interesting or useful in practice,i.e.,anonymity,unlinkablility,unforgeability,coalition-resistance,etc.

在随机预言模型下，可以证明新协议满足了实用匿名订购协议所要求的全部特性，即匿名性、无关联性、不可伪造性、抵抗联合攻击等。

It is proved to be unforgeable in the standard model, and is unconditionally anonymous.

在标准模型下证明其能抵抗签名伪造攻击，且具有无条件匿名性。

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。
