Our engineer did a differential fautl analysis on a smart card - or rather he began the attack. <br>
|

|
|
He went on vacation before the data analysis, so now it's your task, first year intern. <br><br>
|
||
|
|
We'll give you the plaintext, the ciphertext, and 32 faulted ciphertexts. <br>
|
||
|
|
You need to recover the 64 bits key and to submit it in hexadecimal inside the 42CTF{} tag. <br><br>
|
||
|
|
|
||
|
|
Example : 42CTF{1234567890ABCDEF}<br>

Good luck.<br>
