Mind the Faulty Keccak: A Practical Fault Injection Attack Scheme Applied to All Phases of ML-KEM and ML-DSA

IEEE Transactions on Information Forensics and Security
ML-KEM and ML-DSA are NIST-standardized lattice-based post-quantum cryptographic algorithms. In both algorithms, Keccak is the designated hash algorithm extensively used for deriving sensitive information, making it a valuable target for attackers.

A Lightweight Unified Keccak Module for Efficient Hashing in ML-KEM and ML-DSA

Proceedings of the 2025 Quantum Security and Privacy Workshop
One of the major modules used in post-quantum cryptographic (PQC) algorithms is Keccak or SHA-3. For generating the coefficients of the public vector, secret vector, and error vector, different sampler functions receive the output of the Keccak function ...

Algebraic Attacks on Round-Reduced Keccak

2021
Since Keccak was selected as the SHA-3 standard, both its hash mode and keyed mode have attracted lots of third-party cryptanalysis. Especially in recent years, there is progress in analyzing the collision resistance and preimage resistance of round-reduced Keccak.

An Extended Grendel Approach Applied to Blockchain Signature as an Alternative to Keccak Permutation

Statistics, Optimization & Information Computing
In this paper, we present our own developed programming which helps to generate a sponge-based function while avoiding any call from hashing libraries. Then, we try to implement it in a blockchain signature by getting inspired from Keccak methods such as

Practical Analysis of Reduced-Round Keccak

2011
Keccak is a finalist of the SHA-3 competition. In this paper we propose a practical distinguisher on 4 rounds of the hash function with the submission parameters. Recently, the designers of Keccak published several challenges on reduced versions of the hash function. With regard to this, we propose a preimage attack on 2 rounds, a collision attack on 2

Side-Channel Analysis of MAC-Keccak

2013 IEEE International Symposium on Hardware-Oriented Security and Trust (HOST), 2013
NIST recently completed the SHA-3 competition with the selection of Keccak as the new standard for crypto-graphic hashing. In this paper, we present a comprehensive Side-Channel Analysis of Keccak, when it is used with a secret key to generate a Message Authentication Code (MAC) (MAC-Keccak). Our analysis covers all the variations of the algorithm.

Cryptanalysis of 1-Round KECCAK

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.
