An Information Theoretic Perspective on the Di erential Fault Analysis against AES

Di erential Fault Analysis (DFA) against AES has been actively studied these years. Based on similar assumptions of the fault injection, di erent DFA attacks against AES have been proposed. However, it is di cult to understand how di erent attack results are obtained for the same assumption of fault injection. It is also di cult to understand the relationship between similar assumptions of fault injections and the corresponding attack results. This paper reviews the previous DFA attacks against AES from an information theoretic point of view, and gives a general understanding for DFA attacks against AES.
