Improved Meet-in-the-Middle Nostradamus Attacks on AES-like Hashing
IACR Transactions on Symmetric CryptologyThe 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.

A Meaningful MD5 Hash Collision Attack [PDF]
, 2006 It is now proved by Wang et al., that MD5 hash is no more secure, after they proposed an attack that would generate two different messages that gives the same MD5 sum. Many conditions need to be satisfied to attain this collision.

SAT-Based Space Partitioning and Applications to Ascon-Hash256 Cryptanalysis
IACR Transactions on Symmetric CryptologyWe 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 ...

On the Security of Split-and-Lookup-Based ZK-Friendly Primitives
IACR Transactions on Symmetric CryptologyArithmetization-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.
