Rotational Cryptanalysis of Round-Reduced Keccak [PDF]

open access: yes, 2014
In this paper we attack round-reduced Keccak hash function with a technique called rotational cryptanalysis. We focus on Keccak variants proposed as SHA-3 candidates in the NIST’s contest for a new standard of cryptographic hash function. Our main result is a preimage attack on 4-round Keccak and a 5-round distinguisher on Keccak-\(f\)[1600 ...

Cube-Attack-Like Cryptanalysis of Round-Reduced Keccak Using MILP

open access: yesIACR 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 ...

New Conditional Cube Attack on Keccak Keyed Modes

open access: yesIACR Transactions on Symmetric Cryptology, 2019
The conditional cube attack on round-reduced Keccak keyed modes was proposed by Huang et al. at EUROCRYPT 2017. In their attack, a conditional cube variable was introduced, whose diffusion was significantly reduced by certain key bit conditions.
