一种基于矩阵运算的文件数据块加密方法

论文提出一种将文件信息以矩阵方式进行加解密的方法，采用伪随机序列＋异或＋移位＋乱序＋循环密钥的加密方式，与传统的加解密方式相比，加解密过程中密文和信息同时参与加解密。改变加密过程中的伪随机序列发生函数、乱序序列和循环密钥生成方法都可以成生不同的加解密算法。

A Matrix Manipulation-based Method for Encrypting Message Block

The paper puts forward a method for encrypt the message blocks in the form of matrix. This method uses the pseudo-random sequence plus XOR plus shift plus scrambling plus cycle keys to encrypt the matrix, in which the cipher and the message block participate in encryption and decryption in contrast with the traditional encryption methods. A different encryption algorithm can be gained by changing the function of pseudo-random sequence or the generation of shift sequence or cycle keys in the process of encryption.
