1). Decrypt the following using Simple AES.

The key is 1010011100111011 and the ciphertext is 0000011100111000. Find the plaintext pair of ASCII characters (note a = 01100001, . . . , z = 01111010). You should get an amazing message(or at least an ok one).

2).

Create the difference table for the simple AES s-box.

3).

Create the difference table for DES S_1 s-box.

4).

Create the PC-1 transform from DES. It should produce two arrays, C and D.
