Question: 5.12 Carefully write up a complete decryption of the ciphertext 0000 0111 0011 1000 using the key 1010 0111 0011 1011 and the S-AES algorithm.

5.12 Carefully write up a complete decryption of the ciphertext 0000 0111 0011 1000 using the key 1010 0111 0011 1011 and the S-AES algorithm. You should get the plaintext we started with in Problem 5.10. Note that the inverse of the S-boxes can be done with a reverse table lookup. The inverse of the MixColumns step is given by the ma- frix in the nrevious nroblem
