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 ...

Improved Meet-in-the-Middle Nostradamus Attacks on AES-like Hashing

IACR Transactions on Symmetric Cryptology
The Nostradamus attack was originally proposed as a security vulnerability for a hash function by Kelsey and Kohno at EUROCRYPT 2006. It requires the attacker to commit to a hash value y of an iterated hash function H.

SAT-Based Space Partitioning and Applications to Ascon-Hash256 Cryptanalysis

IACR Transactions on Symmetric Cryptology
We introduce an efficient SAT-based space partitioning technique that enables systematic exploration of large search spaces in cryptanalysis. The approach divides complex search spaces into manageable subsets through combinatorial necklace generation ...

Linear Cancellations in the MitM Attacks on Sponge Functions

IACR Transactions on Symmetric Cryptology
At EUROCRYPT 2023, Qin et al. proposed the MitM attack framework on sponge functions by separating the message bits into two sets of neutral bits.

Indifferentiability of the Sponge Hash Family: New Attacks and the Optimal Construction

IACR Transactions on Symmetric Cryptology
The sponge construction is subject to an indifferentiability security bound of c/2 bits, where c denotes the capacity. For a given b-bit permutation, the sponge construction allows sacrificing the rate r = b − c to achieve the theoretically optimal ...

On the Security of Split-and-Lookup-Based ZK-Friendly Primitives

IACR Transactions on Symmetric Cryptology
Arithmetization-Oriented hash functions are optimized for their verification to be efficiently implemented within various proof systems, but they are often too slow when evaluated on a regular machine.
