Practical Preimage Attacks on 3-Round Keccak-256 and 4-Round Keccak[r=640, c=160] [PDF]
IACR Transactions on Symmetric CryptologyRecently, linear structures and algebraic attacks have been widely used in preimage attacks on round-reduced Keccak. Inherited by pioneers’ work, we make some improvements for 3-round Keccak-256 and 4-round Keccak[r=640, c=160].

Cryptanalysis of 1-Round KECCAK [PDF]
, 2018 In this paper, we give the first pre-image attack against 1-round KECCAK-512 hash function, which works for all variants of 1-round KECCAK. The attack gives a preimage of length less than 1024 bits by solving a system of 384 linear equations. We also give a collision attack against 1-round KECCAK using similar analysis.

Side-channel analysis of MAC-Keccak hardware implementations [PDF]
Proceedings of the Fourth Workshop on Hardware and Architectural Support for Security and Privacy, 2015 As Keccak has been selected as the new SHA-3 standard, Message Authentication Code (MAC) (MAC-Keccak) using a secret key will be widely used for integrity checking and authenticity assurance. Recent works have shown the feasibility of side-channel attacks against software implementations of MAC-Keccak to retrieve the key, with the security assessment ...

Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP [PDF]
IACR Transactions on Symmetric Cryptology, 2018 Cube-attack-like cryptanalysis on round-reduced Keccak was proposed by Dinur et al. at EUROCRYPT 2015. It recovers the key through two phases: the preprocessing phase for precomputing a look-up table and online phase for querying the output and getting ...
