WebHence, generally the required number of faults increases in DFA of AES-192 and AES-256. The work by Piret and Quisquater can be extended to attack AES-192 and AES-256 that need four pairs of correct and faulty ciphertexts. In 2009 Li et al. [25] proposed two DFA on AES-192 and AES-256 based on the Moradi et al.’s DFA on AES-128 [28]. Webdescribe AES using matrix on GF(28) but we try to keep the notations of [1]. The AES is a block cipher with block length to 128 bits, and support key lengths N k of 128, 192 or 256 …

WebSep 8, 2008 · In this paper we show a new differential fault analysis (DFA) on the AES-128 key scheduling process. We can obtain 96 bits of the key with 2 pairs of correct and faulty ciphertexts enabling an easy exhaustive key search of 2 32 keys. Furthermore we can retrieve the entire 128 bits with 4 pairs. To the authors' best knowledge, it is the smallest ...
