New findings you should know, when you use AES. The “Holes” we found in the S-Boxes can lead to very efficient “Known Plaintext”and “Ciphertext Only” attacks. We consider this a special type of side channel attack, because you would need to transport the holes out of the system.
The following paper describes how holes can be found and how the key can then be calculated in seconds.
