RSA密码体制的实现及改进方案

摘要：RSA密钥体制是公开密钥体制中最容易理解，也是应用最广泛的1种加密方法，本文在深入研究RSA密钥体制的基础上，使用Boland C++实现了1个小型的RSA加密系统来模拟RSA算法的整个过程。第1章就密码学的发展，古典密码及公开密钥技术进行说明，并对未来密码系统的发展进行了展望。第2，3章，着重分析了RSA公钥体制的原理及算法。第4章分析了RSA体制的不足之处及安全性能，并在此基础上提出1定的改进方案。最后本文着重讲述了实现RSA体制的详细的算法实现程序。

Implementing and Improving Proposal for RSA Cryptosystem
 
Abstract: RSA cryptography system is the easiest system to be understood among the public key cryptography systems and it’s the most populer cryptography system in use. This paper will go into the RSA cryptography system and implement a small cryptosystem using Boland C++ to module the course of the RSA cryptography system.The first chapter of this paper explains the development of cryptography, tradition cryptogram, Public Key Cryptosystem and the future of cryptography.The second and the third chapters of this paper explain the basic theory and arithmetic of RSA Public Key Cryptosystem.The fourth chapter of this paper analyses RSA deficiency and security function. This paper will attempt to give out an improving proposal for RSA cryptosystem.The last chapter of this paper explains the particular implementing procedure.
Keywords: RSA Public Key Cryptosystem;Tradition Key System;Public Key System; Euclidean Algorithm
