摘要
DES数据加密算法具有很强的健壮性,在计算机密码学和数据通信领域中的发展发挥了巨大作用,也在一般的计算机数据传输活动方面提供了有力保障。文章在详细地介绍了DES对称密钥数据加密算法的原理基础上,研究该算法的机理并结合当前主流的程序设计平台在C++的平台下予以实现。
DES data encryption algorithm has strong robustness,plays a significant role in computer cryptography and data communications and provides guarantee for the computer data transmission.This paper introduces the principles of DES symmetric key data encryption algorithm in detail,studies the mechanism of the algorithm and realizes the algorithm under the C＋＋ platform combined with the current mainstream programming platform.
