签名

Ask you to leave documents unsigned or ask for your signature on incomplete or blank documents.

请你离开未签名的文件，或要求您的签名对不完整或空白证件。

This paper has obtained following three results about the new scheme:(1) The hardness of recovering the private key from the public key is based on the hardness of the shortest vector problems of several lattices;(2) The hardness of forging a signature is equivalent to the hardness of the closest vector problem of some lattice;(3) Each signature will leak information on the private key,but the final shape of the unlimited leakage is just a group of complicated non-linear equations.

文中给出新方案的3个结果：(1)由公钥恢复出私钥的困难性基于若干格上的最小向量问题；(2)由公钥伪造签名的困难性等价于某个格上的最近向量问题；(3)每个签名值仍然会泄露私钥的一些信息，但无限制泄露的最终形式只是关于私钥的一组复杂的非线性方程。

We do research on identity based proxy multi-signature and designated verifier proxy signature.

3对基于身份的代理多重签名和指定验证者代理签名进行了研究。

In a designated verifier signature scheme,only the designated verifier can verify the validity of the signature.

在一个指定验证者签名方案中，只有指定的验证者才能验证签名的有效性。

On-line verification takes place as a writer creates his signature on a digital tablet or a similar device to grab dynamic information, while off-line verification is the process of verifying a static signature which is written on white paper and collected by a digital scanner or a video camera.

而脱机签名鉴定只要求提供签名者在普通纸张上的签名，然后通过数字扫描仪或摄像仪采集样本，因此它具有更广阔的应用范围。

A confirmer signature scheme based on RSA is proposed. It is showed that the new scheme is an implementation of secure and efficient confirmer signature.

提出了一种完全基于RSA的证实数字签名方案，分析表明，该方案是一种安全而高效的证实数字签名实现方案。

The subscriber's security and the confirmer signature invisibility are characteristic to a confirmer signature scheme.

签名者的安全性和证实签名的&不可见性&是一个证实数字签名方案必须具备的两个重要特性。

The signature subscriber s security and the confirmer signature s invisibility are characteristic to a confirmer signature scheme.

签名者的安全性和证实签名的&不可见性&是一个证实数字签名方案必须具备的两个重要特性。

The scheme is the improvementof confirmer digital signature. Also it is simpler and doesnt require the participation of the confirmer.

该方案是可证实数字签名的改进，比证实签名简单且不需要第三方的参与。

Meanwhile, a confirmer is able to transfer a confirmer signature into a general signature that can be verified by anyone if he or she can obtain it.

同时证实者具有转化一个证实签名为一个普通数字签名（即：可被任何人公开验证）的能力。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
