换位变换及其在信息加密中的应用

以信息安全问题为背景，提出了换位变换的概念，设计了信息加密的换位变换算法，并分析了算法的安全性。算法过程仅仅使用了换位运算，算法简单，容易实现。序码换位方法选择灵活，算法具有较好的安全性。

Transposition Transform and Its Application in Information Encryption

With the information security problem as the background, the conception of the transposition transform is proposed, an algorithm for transposition transform is designed and the security of the algorithm is analyzed. The number transposition only used in the process of the method, which makes the algorithm is simple and easily implemented by the computer. The selection of the transposition transform is agile, which makes the algorithm has the secure background.
