We consider AES with 128-bit block length and 128-bit key length. What is the output of the first round of AES encryption if the plaintext x consists of sixteen (68)hex (i.e. 01101000 01101000 bit string) and the AES key consists of sixteen (AA)hex (i.e., 10101010 10101010 bit string). You can write your final results in a rectangular matrix format.

Hints: youll have to use AES-128 key schedule to get the subkeys k0 and k1 first. Then you can get your A matrix (16 x 16) by x k0 to start your first round encryption steps ByteSub, ShiftRows, MixCol, and AddSubkey (k1).
