基于双线性对与身份的数字签名方案研究

研究了基于双线性对与身份的可以防止PKG伪造用户有效签名的签名方案,得到几种一般化形式并进行了优化,最后进行了安全分析.

Abstract：

Digital signature, which can provide authentication, integrity and non-repudiation, is a key technique of information security. The authors of this paper propose some new ID-based signatures which can prevent the PKG from forging the signature, and analyse them after optimizing these patterns.     

B92协议的改进与数字签名

对量子密钥分配的B92协议做了一些改进,即通过令发信方Alice故意公布一些假的测量基提高诱使窃听者Eve现身的概率并基于改进的B92协议和RSA加密体制提出了一种双向认证签名方案.

Abstract：

An improvement of B92 quantum key distribution protocol is proposed in this paper. The main idea is to find secret listeners more easily from a trap of the quantum channel by some false basis the sender has inserted. Based on the quantum key distribution protocol of B92 and the RSA public-key cipher system, a new dual safekeeping and mutually authenticated digital signature scheme is constructed.     

基于Matlab的加密算法DES的设计与实现

给出了一种基于Matlab的带有图形用户界面(GUI)的DES程序的设计及实现过程.本程序可以用于实际的加密,更重要的是为DES的教学和实验提供了一个方便直观的工具.

Abstract：

.DES (Data Encryption Standard), which was the most widely used cryptosystem in the world, is still used as a model for teaching and research.This paper describes the design and implementation of a Matlab-based DES encryption algorithm.Our program with a comfortable GUI (graph user interface) can be used in practical encryption.What is more important is that it offers a convenient tool for DES teaching and experiments.
