In this paper, the authors present a lightweight concurrent fault detection scheme for the AES. In the proposed approach, the composite field S-box and inverse S-box are divided into blocks and the predicted parities of these blocks are obtained. They have found the optimum solutions for the least overhead parity-based fault detection structures. Moreover, through their error injection simulations for one S-box (respectively inverse S-box), they show that the total error coverage of almost 100% for 16 S-boxes (respectively inverse S-boxes) can be achieved.
