Keccak-based algorithms such as Secure Hash Algorithm-3 (SHA3) will be widely used in crypto systems, and evaluating their security against different kinds of attacks is vitally important. This paper presents an efficient differential fault analysis (DFA) method on all four modes of SHA-3 to recover an entire internal state, which leads to message recovery in the regular hashing mode and key re...

© 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...

Differential Fault Analysis (DFA) attack is a powerful cryptanalytic technique that could be used to retrieve the secret key by exploiting computational errors in the encryption (decryption) procedure. In the present paper, we propose a new DFA attack on SMS4 using a single fault. We show that if a random byte fault is induced into either the second, third, or fourth word register at the input ...

Biased fault attacks such as the Differential Fault Intensity Analysis (DFIA) have been a major threat to cryptosystems in recent times. DFIA combines principles of side channel analysis and fault attacks to try and extract the key using faulty ciphertexts only. Biased fault attacks have also been shown to weaken traditional redundancy based countermeasures, such as Concurrent Error Detection (...

In September 1996 Boneh, Demillo, and Lipton from Bellcore announced a new type of cryptanalytic attack which exploits computational errors to find cryptographic keys. Their attack is based on algebraic properties of modular arithmetic, and thus it is applicable only to public key cryptosystems such as RSA, and not to secret key algorithms such as the Data Encryption Standard (DES) . In this pa...
