Regarding the mix column operation of the AES round function, it is performed with a pre-defined matrix, i.e., 12 3 1 1] 1 2 3 1 1 1 2 3 L3 1 1 2 Explain why this mix column operation can be implemented with a simple look up table and XOR (4 marks). Apply the same idea used above, explain why the byte substitution, shift row and mix column can be combined together and implemented as a simple look up table operation. And then the whole AES is implemented by look up table and few XORs
