"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]. " - Dfa on aes
