Automatic Preimage Attack Framework on Ascon Using a Linearize-and-Guess Approach [PDF]
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.

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.

Preimage Attacks on Reduced Tiger and SHA-2 [PDF]
Lecture Notes in Computer Science, 2009 This paper shows new preimage attacks on reduced Tiger and SHA-2. Indesteege and Preneel presented a preimage attack on Tiger reduced to 13 rounds (out of 24) with a complexity of 2128.5. Our new preimage attack finds a one-block preimage of Tiger reduced to 16 rounds with a complexity of 2161. The proposed attack is based on meet-in-the-middle attacks.

New Preimage Attacks Against Reduced SHA-1 [PDF]
Lecture Notes in Computer Science, 2012 This paper shows preimage attacks against reduced SHA-1 up to 57 steps. The best previous attack has been presented at CRYPTO 2009 and was for 48 steps finding a two-block preimage with incorrect padding at the cost of $$2^{159.3}$$ evaluations of the compression function.

A Second Preimage Attack on the XOR Hash Combiner
IET Information SecurityThe exclusive-or (XOR) hash combiner is a classical hash function combiner, which is well known as a good PRF and MAC combiner, and is used in practice in TLS versions 1.0 and 1.1.

Preimage Attacks on 3, 4, and 5-Pass HAVAL [PDF]
Lecture Notes in Computer Science, 2008 This paper proposes preimage attacks on hash function HAVAL whose output length is 256 bits. This paper has three main contributions; a preimage attack on 3-pass HAVAL at the complexity of 2225, a preimage attack on 4-pass HAVAL at the complexity of 2241, and a preimage attack on 5-pass HAVAL reduced to 151 steps at the complexity of 2241. Moreover, we

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 ...
