实现DES加密算法安全性的分析与研究

Analysis and research on realizing the security of DES encryption algorithm

文章主要研究探析了DES加密算法安全性问题,首先介绍了实现DES加密算法安全性的过程,主要包括两个方面的内容:DES算法的工作流程以及DES算法的加密过程,并通过这两个方面的内容,分析了DES算法的IP变换以及逆变换和S盒换位表等问题,并找出了其中存在的换位规则。之后在此基础上,探讨了DES算法实现方法的改进方法,希望能够为以后相关方面的研究工作提供一些参考。

The article mainly studies and analyzes the security problem of the DES encryption algorithm.First,it introduces the process of implementing the security of the DES encryption algorithm,which mainly includes two aspects:the workflow of the DES algorithm and the encryption process of the DES algorithm,and through these two aspects The content of the DES algorithm is analyzed,such as IP transformation,inverse transformation and S box transposition table,and the transposition rules existing therein are found.After that,the improvement method of the DES algorithm implementation method is discussed.Provide some reference for the related research work in the future.
