用MATLAB实现HILL密码的加密与解密

Using Matlab to Achieve Encrypting and Decrypting Hill Cipher

在当今的通讯领域,信息的安全性非常重要,因此常常需要对信息进行加密和解密。作为以代数为基础的密码学,HILL密码具有一定的实用价值。依照HILL密码的原理,借助MATLAB,准确快速地实现HILL密码的加密和解密。

In today ＇ s communications,the confidentiality of information is especially important,so we have to encrypt and decrypt our messages quite frequently. As a cryptography based on algebra,Hill Cipher is very valuable for us. In this paper,according to the principle of Hill Cipher,we encrypt and decrypt our messages quickly and exactly by using MATLAB.
