TIDAL: Practical Collisions on State-Reduced Keccak Variants [PDF]
, 2023 An important tool that has contributed to collision search on Keccak/SHA3 is the Target Difference Algorithm (TDA) and its inter- nal differential counterpart Target Internal Difference Algorithm (TIDA), which were introduced by Dinur et al.

Higher-Order Differential Properties of Keccak and Luffa [PDF]
International Journal of Advanced Computer Science and Applications, 2011 In this paper, we identify higher-order differential and zero-sum properties in the full Keccak-f permutation, in the Luffa v1 hash function and in components of the Luffa v2 algorithm. These structural properties rely on a new bound on the degree of iterated permutations with a nonlinear layer composed of parallel applications of a number of balanced ...

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 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
