Question 4: (53=15 points)
Consider the following plaintext and key for AES encryption.
Plaintext:
Key:
i. Show the original contents of input State, displayed as 44 matrix.
ii. Show the value of State after initial AddRoundKey. Remember, the initial round key is
w0,w1,w2,w3 which is generated from the given key. Ans should be a 44 matrix.
iii. Show the value of State after SubBytes transformation in round 1. Assume the same S-box
being used from the slides. Ans should be a 44 matrix.
