IACR Transactions on Symmetric Cryptology, 2016 In this paper, we describe attacks on the recently proposed Haraka hash functions. First, for the two hash functions Haraka-256/256 and Haraka-512/256 in the family, we show how two colliding messages can be constructed in about 216 function ...

CoRR, 2014 We propose a preimage attack against cryptographic hash functions based on the speedup enabled by quantum computing. Preimage resistance is a fundamental property cryptographic hash functions must possess. The motivation behind this work relies in the lack of conventional attacks against newly introduced hash schemes such as the recently elected SHA-3 ...

A second preimage attack on zipper hash
Security and Communication Networks, 2015 AbstractThe zipper hash utilizes two‐pass hashing to strengthen the iterated hash functions against the generic attack. In this paper, we analyze the features of zipper hash and several existing generic attacks on hash functions. A new tree structure called inverse‐diamond, which starts from one fixed point and ends with many points, is exploited to ...

Allocating Rotational Cryptanalysis based Preimage Attack on 4-round Keccak-224 for Quantum Setting [PDF]
, 2022 In this paper, we aim to present a quantum setting oriented preimage attack against 4-round Keccak-224. An important technique we called the allocating rotational cryptanalysis takes the preimage attack into the situation of 2-block preimage recovery ...

A (Second) Preimage Attack on the GOST Hash Function [PDF]
, 2008 In this article, we analyze the security of the GOST hash function with respect to (second) preimage resistance. The GOST hash function, defined in the Russian standard GOST-R 34.11-94, is an iterated hash function producing a 256-bit hash value. As opposed to most commonly used hash functions such as MD5 and SHA-1, the GOST hash function defines, in ...

Preimage Attacks on the Round-reduced Keccak with Cross-linear Structures
IACR Transactions on Symmetric Cryptology, 2017 In this paper, based on the work pioneered by Aumasson and Meier, Dinur et al., and Guo et al., we construct some new delicate structures from the roundreduced versions of Keccakhash function family. The new constructed structures are called cross-linear

Advanced Science, Volume 13, Issue 60, 28 October 2026.An electro‐templating strategy directs the relaxation of cholesteric finger loops into discrete concentric rings whose geometry is electrically programmed. The photopolymerized structures retain the topological defect pattern and, upon heating, show reversible, castle‐like surface modulation.

Preimage Attack on Parallel FFT-Hashing [PDF]
, 2007 Parallel FFT-Hashing was designed by C. P. Schnorr and S. Vaudenay in 1993. The function is a simple and light weight hash algorithm with 128-bit digest.
