Improved Preimage Attacks on 4-Round Keccak-224/256
IACR Transactions on Symmetric Cryptology, 2021 This paper provides an improved preimage attack method on standard 4-round Keccak-224/256. The method is based on the work pioneered by Li and Sun, who design a linear structure of 2-round Keccak-224/256 with 194 degrees of freedom left.

Improved Preimage Attacks on 3-Round Keccak-224/256
IACR Transactions on Symmetric Cryptology, 2021 In this paper, we provide an improved method on preimage attacks of standard 3-round Keccak-224/256. Our method is based on the work by Li and Sun. Their strategy is to find a 2-block preimage instead of a 1-block one by constructing the first and second

Improving security of lightweith SHA-3 against preimage attacks [PDF]
International Journal of Electronics and Telecommunications, 2018 In this article we describe the SHA-3 algorithm and its internal permutation in which potential weaknesses are hidden. The hash algorithm can be used for different purposes, such aspseudo-random bit sequences generator, key wrapping or one pass ...

Improved MITM Cryptanalysis on Streebog
IACR Transactions on Symmetric Cryptology, 2022 At ASIACRYPT 2012, Sasaki et al. introduced the guess-and-determine approach to extend the meet-in-the-middle (MITM) preimage attack. At CRYPTO 2021, Dong et al.

Preimage Attack on BioHashing [PDF]
Proceedings of the 10th International Conference on Security and Cryptography, 2013 Biometric recognition is more and more employed in authentication and access control of various applications. Biometric data are strongly linked with the user and do not allow revocability nor diversity, without an adapted post-processing. Cancelable biometrics, including the very popular algorithm BioHashing, is used to cope with the underlying ...

Automatic Preimage Attack Framework on Ascon Using a Linearize-and-Guess Approach
IACR Transactions on Symmetric Cryptology, 2023 Ascon is the final winner of the lightweight cryptography standardization competition (2018 − 2023). In this paper, we focus on preimage attacks against round-reduced Ascon.

Classical and Quantum Meet-in-the-Middle Nostradamus Attacks on AES-like Hashing
IACR Transactions on Symmetric Cryptology, 2023 At EUROCRYPT 2006, Kelsey and Kohno proposed the so-called chosen target forced-prefix (CTFP) preimage attack, where for any challenge prefix P, the attacker can generate a suffix S such that H(P∥S) = y for some hash value y published in advance by the ...

Preimage Attack on 23-Step Tiger [PDF]
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2011 This paper evaluates the preimage resistance of the Tiger hash function. To our best knowledge, the maximum number of the attacked steps is 17 among previous preimage attacks on Tiger, where the full version has 24 steps. Our attack will extend the number of the attacked steps to 23.
