查询词典 key signature

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。

Digital signature operates the born and a series of sign and codes to constitute the electronics password to carry on the signature through a certain password , replace to the writing signature or an official seals , to confirm the body , the data source and integrities of signs , keeping data from burglarize to take , distort and break , thus to attain the purpose of protecting the data

数字签名是通过某种密码运算生成一系列符号及代码组成电子密码进行签名，来代替书写签名或印章，确认签名者的身份、数据来源和完整性，防止数据被窃取、篡改和破坏，从而达到保护数据的目的。

The distributive signature and cheat-proof secret sharing scheme are used during the course of the signature in this scheme. Compared with recent RSA digital signature,this scheme has a higher security.

该方案在签名过程中溶入了部分签名和防欺骗的秘密共享方案，相比于现有的RSA签名方案，该方案具有更高的安全性。

It is based on the difficulty of computing the discrete logarithm modulo for a composite number and the factorization problem of large integer.The size of the group signature and verification time of the group signature are equivalent to that of an individual signature.

该方案的安全性是基于求离散对数和RSA大整数因式分解的困难，其群签名长度和群签名的验证时间只相当于一般个人签名。

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。

Blind group signature scheme is group signature scheme with the characteristic of blind signature, which is widely applied in electronic commerce and electronic government.

摘要盲群签名方案是具有盲签名特点的群签名方案，在电子商务和电子政务中都有重要的应用。

One-time Signature is a type of signature scheme which is very fast based on one way function without trapdoor. Together with Merkle Tree, One-time Signature can be used to construct a solution to Multicast Source Authentication problem.

一次签名是一类基于无陷门单向函数的快速的数字签名，结合使用Merkle树来进行密钥管理，可用来构造组播源认证方案。
