WebOct 21, 2009 · Metrics. 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 … WebAug 1, 2024 · 4 Proposed DFA Attack on AES-192. AES-192 key can be a 2-D array of 32 bit word arranged in 4 rows. DFA byte attack on AES-192 includes inducing fault and obtain round keys, which on further mathematical analysis would give us AES-192 key. The primary step involves inducing fault in the key-11 just before scheduling key-12.

Web(AES) [1]. Subsequently, many DFA were proposed on AES cryptosystem [6,11, 14,15,17] with the aim to reduced the number of faulty ciphertext required by the attack. However the DFA on AES can be divided into two categories. One in which the fault is induced in AES states, another in which the fault is induced in the key schedule.

"WebAug 13, 2010 · In this paper, we revisit P&Q's DFA on AES and we explain how this attack can be much more efficient than originally claimed. In particular, we show that only 2 (resp. 3) faulty ciphertexts allow an attacker to efficiently recover the key in the case of AES-192 (resp. AES-256). Our attack on AES-256 is the most efficient attack on this key ... " - Dfa on aes

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 ... WebIn this paper we describe two different DFA attacks on the AES. The first one uses a fault model that induces a fault on only one bit of an intermediate result, hence allowing us to obtain the key by using 50 faulty ciphertexts for an AES-128. The second attack uses a more realistic fault model: we assume that we may induce a fault on a whole byte.
