Abstract : This paper addresses an efficient concurrent fault detection scheme for the SBox hardware implementation of the AES algorithm. Concurrent fault detection is important not only to protect the encryption/decryption process from random and production faults. It will also protect the system against side-channel attacks, in particular fault-based attacks, i.e. the injection of faults in order to retrieve the secret key. We will prove that our solution is very effective while keeping the area overhead very low.
