Differential fault analysis of AES: Toward reducing number of faults
Differential Fault Analysis (DFA) finds the key of a block cipher using differential information between correct and faulty ciphertexts obtained by inducing faults during the computation of ciphertexts. Among many ciphers AES has been the main target of DFA due to its popularity. DFA of AES has also been diversified into several directions: reducing the required number of faults, applying it to...
متن کاملNew Differential Fault Analysis on AES Key Schedule: Two Faults Are Enough
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 keys. Furthermore we can retrieve the entire 128 bits with 4 pairs. To the authors’ best knowledge, it is the smallest number of pairs to find the entire AES-128 key with a...
متن کاملEfficient Differential Fault Analysis for AES
This paper proposes improved post analysis methods for Differential Fault Analysis (DFA) against AES. In detail, we propose three techniques to improve the attack efficiency as 1) combining previous DFA methods, 2) performing a divide-and-conquer attack by considering the AES key-schedule structure, and 3) taking the linearity of the MixColumns operation into account. As a result, the expectati...
متن کاملDifferential Fault Analysis for Round - Reduced AES by Fault Injection
© 2011 ETRI Journal, Volume 33, Number 3, June 2011 This paper presents a practical differential fault analysis method for the faulty Advanced Encryption Standard (AES) with a reduced round by means of a semi-invasive fault injection. To verify our proposal, we implement the AES software on the ATmega128 microcontroller as recommended in the standard document FIPS 197. We reduce the number of r...
متن کاملRelaxed Differential Fault Analysis of SHA-3
In this paper, we propose a new method of differential fault analysis of SHA-3 which is based on the differential relations of the algorithm. Employing those differential relations in the fault analysis of SHA-3 gives new features to the proposed attacks, e.g., the high probability of fault detection and the possibility of re-checking initial faults and the possibility to recover internal state...
