| Abstract: | Differential Fault Analysis against AES has been actively studied these years. Based on similar assumptions of the fault injection, different DFA attacks against AES have been proposed. However, it is difficult to understand how different attack results are obtained for the same fault injection. It is also difficult to understand the relationship between similar assumptions of fault injection and the corresponding attack results. This paper reviews the previous DFA attacks against AES based on the information theory, and gives a general and easy understanding of DFA attacks against AES. We managed to apply the analysis on DFA attacks on AES-192 and AES-256, and we propose the attack procedures to reach the theoretically minimal number of fault injections. |
