简易的矩陣加密編编码法
- 算法介绍 矩阵求逆在程序中很常见,主要应用于求Billboard矩阵。按照定义的计算方法乘法运算,严重影响了性能。在需要大量Billboard矩阵运算时,矩阵求逆的优化能极大提高性能。这里要介绍的矩阵求逆算法称为全选主元高斯-约旦法。 高斯-约旦法(全选主元)求逆的步骤如下: 首先,对于 k 从 0 到 n - 1 作如下几步: 从第 k 行、第 k 列开始的右下角子阵中选取绝对值最大的元素,并记住次元素所在的行号和列号,在通过行交换和列交换将它交换到主元素位

AES
- AES加密过程是在一个4×4的字节矩阵上运作,这个矩阵又称为“体(state)”,其初值就是一个明文区块(矩阵中一个元素大小就是明文区块中的一个Byte)。(Rijndael加密法因支持更大的区块,其矩阵行数可视情况增加)加密时,各轮AES加密循环(除最后一轮外)均包含4个步骤: 1.AddRoundKey — 矩阵中的每一个字节都与该次回合金钥(round key)做XOR运算;每个子密钥由密钥生成方案产生。 2.SubBytes — 通过一个非线性的替换函数,用查找表的方式把每个
