摘要
介绍了信息加密技术中的置换法及其加密解密思想.采用置换法对文本文件中的字符信息进行加密,给出了一个完整的加密和解密软件制作的程序设计方法和详细步骤,并用C语言进行了具体实现.该软件在信息的传输和存储上具有较高的安全性,能有效防止信息被破解.
Thoughts on replacement algorithm as well as encryption and decryption of information encryption technology were introduced.Replacement algorithm was adopted to encrypt the characters in text files,whose a method of formula design for the comprehensive making process of an encryption and decryption software was given.C language was used to implement it.The findings show that this software has high safety in aspects of information transmit and sotre,which can prevent the information from being decrypted.
