inv_addroundkey.cpp

之前看書參考試著自己寫 但沒成功 請網上較強的大哥試著修改一下 謝啦

#include "stdafx.h"
#include "Inv_AddRoundKey.h"											//Different



void Inv_AddRoundKey(int state[4][4],int Round_count)
{
	int round_key[4][4];
	int i,j;
	get_round_key(round_key,Round_count);

	for(i=0;i<4;i++)
	{
		for(j=0;j<4;j++)
		{
			state[i][j]=state[i][j]^round_key[i][j];
		}
	}
}
