演示
CODEGATE2025
下面用CODEGATE2025的一道题来了解一些矩阵操作。
其实就是一些矩阵的操作，如下图
前面的密钥填充和拓展可以直接动调获取。
输入24*24大小的数据，断点在第一个block3()函数。这里ida有点问题调试看不到变量的数据，可以单步进入block3()函数在进行第一步操作前查看buf的值。
看到矩阵的结构，其实就是用密钥和0包围了一圈，这样的26x26矩阵刚好被3x3的矩阵卷积为24x24的矩阵进行操作。
后面的矩阵操作都基于这个24x24的矩阵，把接下来的操作用python模拟一下。
import numpy as np
def op1(A): #卷积操作
B = np.zeros((24, 24), dtype=int)
for i in range(24):
for j in range(24):
values = [
A[i + 2][j + 2], A[i + 2][j + 1], A[i + 2][j],
A[i + 1][j + 2], A[i + 1][j + 1], A[i + 1][j],
A[i][j + 2], A[i][j + 1], A[i][j]
]
B[i][j] = sum(values)
return B

提取出密文按照矩阵操作进行逆运算。原本打算用numpy来求逆矩阵，但是因为python的数据是没有定义长度大小的，所以numpy会算出小数。而我们的原文加密中，需要把大小维持在0xffff以内，所以我们需要为这个运算规定一个运算域，这里用sage的Zmod(2**16 - 1)实现，并用”“求解逆矩阵。即matrix(Fp, G)是在域Fp下求G的逆矩阵。这样求出的结果就是正常的。
