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 ... WebDec 14, 2016 · Differential fault analysis (DFA) aiming at the advanced encryption standard (AES) hardware implementations has become a widely research topic. Unlike theoretical model, in real attack scenarios, popular and practical fault injection methods like supply voltage variation will introduce faults with random locations, unknown values and …

WebFeb 1, 2012 · An improved attack in [54] showed that a DFA on AES key schedule is possible using two pairs of fault-free and faulty ciphertexts and a bruteforce search of 48-bit. Subsequently, there are two ... 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 …
WebDec 19, 2016 · DFA on AES-128 Encryption. Let us present briefly the DFA attack described by Dusart, Letourneux and Vivolo in 2002 . The general requirements of a DFA attack are: The output must be observable … 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.
WebMar 2, 2024 · The proposed case study explains the main techniques that can break the security of the considered AES design using two different attacks on the AES: the scan-based and the DFA attack. In order to secure the 32-bit AES crypto-core under test a test vector encryption countermeasure based on using a lightweight block cipher is used to …
