RSA密碼體制的實(shí)現及改進(jìn)方案

摘要：RSA密鑰體制是公開(kāi)密鑰體制中最容易理解，也是應用最廣泛的1種加密方法，本文在深入研究RSA密鑰體制的基礎上，使用Boland C++實(shí)現了1個(gè)小型的RSA加密系統來(lái)模擬RSA算法的整個(gè)過(guò)程。第1章就密碼學(xué)的發(fā)展，古典密碼及公開(kāi)密鑰技術(shù)進(jìn)行說(shuō)明，并對未來(lái)密碼系統的發(fā)展進(jìn)行了展望。第2，3章，著(zhù)重分析了RSA公鑰體制的原理及算法。第4章分析了RSA體制的不足之處及安全性能，并在此基礎上提出1定的改進(jìn)方案。最后本文著(zhù)重講述了實(shí)現RSA體制的詳細的算法實(shí)現程序。

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
