Differential Fault Analysis of Streebog

2015
In August 2012, the Streebog hash function was selected as the new Russian federal hash function standard (GOST R 34.11-2012). In this paper, we present a fault analysis attack on this new hashing standard. In particular, our attack considers the compression function in the secret key setting where both the input chaining value and the message block ...

Improved Differential Fault Analysis on CLEFIA

2008 5th Workshop on Fault Diagnosis and Tolerance in Cryptography, 2008
We propose a more efficient differential fault analysis (DFA) attack on CLEFIA, the 128-bit block cipher developed by Sony Corporation in 2007. In the previous study, the most efficient DFA attack on CLEFIA with a 128-bit key uses approximately 18 pairs of correct and faulty ciphertexts.

Differential Fault Analysis on SHACAL-1

2009 Workshop on Fault Diagnosis and Tolerance in Cryptography (FDTC), 2009
SHACAL-1, known as one of the finalists of the NESSIE project, originates from the compression component of the widely used hash function SHA-1. The requirements of confusion and diffusion are implemented through mixing operations and rotations other than substitution and permutation, thus there exists little literature on its immunity against fault ...

Differential Fault Analysis of Twofish

2013
In this paper we propose Differential Fault Analysis (DFA) of Twofish which was one of the five AES finalists. It uses the concept of key-dependent S-boxes and Pseudo-Hadamard Transform, which make the cipher secure against differential attack. Each S-box is dependent on key because of which the S-box is not known to the attacker.

Improved Differential Fault Analysis of CLEFIA

2013 Workshop on Fault Diagnosis and Tolerance in Cryptography, 2013
CLEFIA is already shown to be vulnerable to differential fault analysis (DFA). The existing state-of-the-art DFA shows that two faults are enough to break CLEFIA-128, whereas for CLEFIA-192 and CLEFIA-256 ten faults are needed. Side-by-side it emphasizes the need for protecting last four rounds of the cipher in order to make it secure against the ...

Differential Fault Analysis Using Symbolic Execution

Proceedings of the 7th Software Security, Protection, and Reverse Engineering / Software Security and Protection Workshop, 2017
Differential fault analysis (DFA) is a cryptanalytic attack that uses corrupted cipher executions to extract secret/private keys. Traditionally applied in hardware-based systems, it is now being actively used in extracting keys from (whiteboxed) software cipher implementations.

Differential Fault Analysis of SHA-3 Under Relaxed Fault Models

Journal of Hardware and Systems Security, 2017
Keccak-based algorithms such as Secure Hash Algorithm-3 (SHA-3) will be widely used in cryptosystems, 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 ...

Fault Space Transformation: A Generic Approach to Counter Differential Fault Analysis and Differential Fault Intensity Analysis on AES-Like Block Ciphers

IEEE Transactions on Information Forensics and Security, 2017
Classical fault attacks, such as differential fault analysis(DFA) as well as biased fault attacks, such as the differential fault intensity analysis (DFIA), have been a major threat to cryptosystems in recent times. DFA uses pairs of fault-free and faulty ciphertexts to recover the secret key.

Differential Fault Analysis of SHA-3

2015
In this paper we present the first differential fault analysis DFA of SHA-3. This attack can recover the internal state of two versions of SHA-3 namely, SHA3-512 and SHA3-384 and can be used to forge MAC's which are using these versions of SHA-3. Assuming that the attacker can inject a random single bit fault on the intermediate state of the hash ...

Differential Fault Analysis of HC-128

2010
HC-128 is a high speed stream cipher with a 128-bit secret key and a 128-bit initialization vector. It has passed all the three stages of the ECRYPT stream cipher project and is a member of the eSTREAM software portfolio. In this paper, we present a differential fault analysis attack on HC-128.
