下载后可任意编辑河南农业大学本科生毕业论文 题 目 基于 C++ 的 DES 算法实现 学 院 专业班级 学生姓名 指导老师 撰写日期： 年 月 日基于 C++的 DES 算法实现摘要随着科技的进展，人们在享受信息资源所带来的巨大的方便的同时，信息安全也面临着的巨大考验，信息技术的迅猛进展使得网络环境变得日益复杂。因此，数据加密便成为了当前我们面下载后可任意编辑临的一大问题，其目的是使信息通过互联网传输时，即使被窃取或截获，也让对方不能了解其真正的含义，对于非法使用者来说，相当于一段乱码。通过这次讨论发现了 DES 算法是当下使用比较广泛的加密算法，也是最有代表性的分组加密算法，虽然 DES 加密算法在一些技术面前有被破解的风险，但凭借其自身的优点，相关产品仍然占据市场的主导地位，目前较为广泛的应用于通信加密之中。本文首先讨论了 DES 算法的基本原理,并且分析了 DES 算法的优缺点,通过查资料编写了 C++的源代码。并且在后续的讨论实验中,在所编写的程序上计算得出了加密后的数据。关键词：DES 加密算法；数据安全下载后可任意编辑The realization of RSA algorithm based on C++WANG TaoAbstractWith the development of science and technology, people in the enjoyment of information resources to bring great convenience at the same time, information security also faces a huge challenge, the rapid development of information technology makes the network environment has become more and more complex. Therefore, data encryption has become a big problem we are facing. The purpose is to make the information through the Internet transmission, even if the theft or intercepted, also let your opponent cannot understand the true meaning of, for illegal users, which is equivalent to a garbled. Firstly, .Through the study found that the DES algorithm is today widely encryption algorithm, is also the most representative block encryption algorithm, although the DES encryption algorithm in front of some technology has being cracked, but with its own advantages, related products m...
