1.Consider an encryption and decryption using S-DES with a key, K = 1100 0011 11.
a) Generate the keys, K1 and K2 that will be used in the algorithm.
b) Encrypt the ASCII code for “M” and get the ciphertext.
c) Decrypt the ciphertext to restore the plaintext
2. Consider an encryption and decryption using Mini-AES with a key, K0 = 1010 0000 1011 0001.
a) Generate the keys, K1 and K2 that will be used in the algorithm.
b) Encrypt the ASCII code for “MU” and get the ciphertext. (Each capital letter with 8 bits).

b) Encrypt the ASCII code for “MU”:
Encrypting "M":
Encrypting "U":
Concatenate the results: 10101010 11001100
