精品  文件的加密与解密算法研究与实现 摘要：随着信息社会的到来，人们在享受信息资源所带来的巨大的利益的同时，也面临着信 息安全的严峻考验。信息安全已经成为世界性的现实问题，信息安全问题已威胁到国家的政 治、经济、军事、文化、意识形态等领域，同时，信息安全问题也是人们能否护自己的个人 隐私的关键。信息安全是社会稳定安全的必要前提条件。 本文是一篇讨论关于常用文件加密解密算法的毕业设计论文，它详细的讲述了文件加密解密算法实现的过程中所用到的方法、技术。对公钥密码体制和私钥密码体制进行了分析和研究，并对公钥密码体制和私钥密码体制的代表RSA算法和DES算法进行了研究和比较。 关键词：解密；文件加密；密码体制；DES；RSA Design and Implementation of Document tagging software Abstract: With the advent of the information society, people in the enjoyment of information resources brought about tremendous benefits, but also faced with a letter Income security, a severe test. Information security has become a worldwide reality, information security has been a threat to the countrys political Governance, economic, military, cultural, ideological and other areas at the same time, the issue of information security is also a possibility of retaining their own personal Privacy key. Information security and social stability is a necessary precondition for security. ? This article is a discussion paper on encryption and decryption algorithms commonly used in graduate design thesis, which documents in detail about the encryption and decryption process of algorithm used in the methods and techniques. Of public-key cryptosystem private key cryptosystem and analysis and research, and public-key cryptosystem and on behalf of private key cryptography algorithm RSA algorithm and DES have been studied and compared. Keywords: Decryption; file encryption; cryptosystem; DES; RSA 目录 摘要……………………………………………………………………2 TOC \o 1-3 \h \z \u HYPERLINK file:///C:\\Documents%20and%20Settings\\Administrator\\桌面\\毕业设计.doc \l _Toc227297335#_Toc227297335 目录 PAGEREF _Toc227297335 \h 3 HYPERLINK file:///C:\\Documents%20and%20Settings\\Administrator\\桌面\\毕业设计.doc \l _Toc227297336#_Toc227297336 1、前言 PAGEREF _Toc227297336 \h 4 HYPERLINK file:///C:\\Documents%20and%20Settings\\Administrator\\桌面\\毕业设计.doc \l _Toc227297337#_Toc227297337 2、需求分析 PAGEREF _Toc227297337 \h 5 HYPERLINK file:///C:\\Documents%
