Abstract :
In CHES 2006, M. Amir et al. introduced a generalized method of differential fault attack (DFA) against AES-128. Their fault models cover all locations before the 9th round in AES-128. However, their method cannot be applied to AES with other key sizes, such as AES-192 and AES-256. On the differential analysis, we propose a new method to extend DFA on AES with all key sizes. Our results in this study will also be beneficial to the analysis of the same type of other iterated block ciphers.
