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 … 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].

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. 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. golf courses conroe texasWebPaper: FPGAhammer: Remote Voltage Fault Attacks on Shared FPGAs, suitable for DFA on AES.
