For this exercise you will break 8 rounds of TC02 (the full cipher) a cipher designed to have (really) poor diffusion. It is an AES like cipher with a 64-bit state and a 64-bit key (see the specifications for more information). The goal is to find the full encryption key using a Meet in the Middle (MitM) attack.
The data you get for this exercise is 32 plaintext-ciphertext pairs.
