Abstract: This paper describes a differential fault analysis (DFA) on AES with 192 and 256-bit keys. We show a new attack in which both 192 and 256-bit keys are retrieved within a feasible computational time. In order to verify the proposed attack and estimate the calculation time, we implement the proposed attack using C code on a PC. As a result, we successfully recover the original 192-bit key using 3 pairs of correct and faulty ciphertexts within 5 minutes, and 256-bit key using 2 pairs of correct and faulty ciphertexts and 2 pairs of correct and faulty plaintexts within 10 minutes.
