This question is related to the AES key schedule. Consider round 0 in AES where the key consists of 128 bits, each of which is 0. (a) Show that the key for the first round is: W (4) W(5) W(6) = W(7) = - (b) Show that: - W(8) = W (10) # W (9) = W(11) 0110 010 01100011 01100011 01100011 This question is related to the AES key schedule.
