An Improved Fault Based Attack of the Advanced Encryption Standard

In the present paper a new fault based attack has been proposed against AES-Rijndael. The paper shows that inducing a single random byte fault at the input of the eighth round of the AES algorithm the block cipher key can be deduced. Simulations show that when two faulty ciphertext pairs are generated, the key can be exactly deduced without any brute-force search. Further results show that with one single faulty ciphertext pair, the AES key can be ascertained with a brute-force search of 232.
