Fault attacks are powerful and efficient cryptanalysis techniques to find the secret key of the Advanced Encryption Standard (AES) algorithm. These attacks are based on injecting faults into the structure of the AES to obtain the confidential information. To protect the AES implementation against these attacks, a number of countermeasures have been proposed. In this paper, the authors propose a fault detection scheme for the Advanced Encryption Standard. They present its details implementation in each transformation of the AES. The simulation results show that the fault coverage achieves 99.999% for the proposed scheme.
