1. AES design from scratch based on https://github.com/boppreh/aes/blob/master/aes.py and the book The Rjindael Design.
2. Differential Fault attack on round 9 in Python and C.
3. Differential Fault attack on round 8 in C.

For the program written in C.
For the simple DFA on Encryption on 8th Round, it ran 11 hrs on my computer,
while the DFA on Encryption on 8th Round with 2 phases takes 3.5hrs on my computer.
For the 9th round Encryption it took roughly 2-5 mins.

For program written in Python,
It took 3.5hrs to run the 9th round Encryption.

The structure of the data for AES is as follows:

The matrix[i][j] means i is the column and j is the row.
We converting from b0,b1,b2,....,b15 as
b0 b4 b8 b12
b1 b5 b9 b13
b2 b6 b10 b14
b3 b7 b11 b15
