毕业设计（论文）-RSA公开密钥密码体制的研究及实现.doc

摘要
当今世界信息技术获得了前所未有的大发展,因而信息的安全性必将变得越来越受到人们的重视。而数字签名技术是目前网络安全领域的研究热门方向。
RSA算法是第一个能同时用于加密和数字签名的算法,易于应用和理解。RSA从提出一直到现在,它经历了各种考验。它通过认证技术来分辨真与假。RSA数字签名体制使用地是RSA公开密钥算法进行得数字签名。
本文主要是对RSA公开密钥密码体制的研究,并在此基础上实现了RSA的数字签名的体制。本文的主要内容包括:
第一:在查阅大量文献资料的基础上,分析了密码学领域里,公钥加密体制的优点所在及其RSA数字签名的安全性(攻击性);第二:简述了DSA以及椭圆曲线数字签名,深入分析RSA算法的理论基础及算法原理,包括RSA大素数的产生,密钥对的产生,以及对明文的加密和解密:第三:对MD5算法基本原理的详细介绍。第四:阐述了RSA数字签名的设计与实现,其中包括RSA公钥和私钥的产生,RSA加密与解密算法的实现,消息摘要的生成,还有就是利用RSA加密算法实现数字签名以及签名的验证。第五,简要陈述数字签名的用途。
关键词: 加密解密 RSA算法 RSA数字签名


Abstract
Now the information of the world is developing the security of the information is ing more and more importantly. Digital signature filed will e hot spots in future.
It is the first algorithm for both data encryption and digital can be understood easily by has undergone various tests when it is put as the public key cryptosystem representative approved data integrity is a kind of information technology. It is through the authentication techniques to distinguish true and false. RSA digital signature system using a RSA public key algorithm for digital signature.
The text is about the study of RSA public key encryption,based on this generating RSA digital :
,Firstly on the basis of previous research, a system based on elliptical curve proxy signature, The advantage of public key encryption and the security of RSA digital signature(attack )Secondly,it analyzes the principle of RSA,including how to generat a prime number,how to generat the secret keys and how to encryption as well as decrypt, Thirdly,it states the principle of MD5 in , it states design and realization of RSA digital signature in detail. The main modules includes producing RSA secret keys, implementation of RSA encryption algorithm and decryption algorithm, producing message digest and realizing digital signature and verification by RSA.
Key words: RSA algorithm; encryption; decryption; RSA digital signature
