Question
In this assignment, you have to implement a Differential Fault Attack on AES. You would be supplied with two pairs of faulty and correct ciphertext and using that you need to recover the first column (first 32 bits) of the round 10 key. The two pairs of faulty and correct ciphertext for each group are as given below:
