Malicious Keccak. [PDF]

open access: yesIACR Cryptol. ePrint Arch., 2015
In this paper, we investigate Keccak --- the cryptographic hash function adopted as the SHA-3 standard. We propose a malicious variant of the function, where new round constants are introduced.

Higher-Order Differential Properties of Keccak and Luffa [PDF]

open access: yesInternational 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 ...

Multi-Core Dataflow Design and Implementation of Secure Hash Algorithm-3

open access: yesIEEE Access, 2018
Embedded multi-core systems are implemented as systems-on-chip that rely on packet storeand-forward networks-on-chip for communications. These systems do not use buses or global clock.

Algebraic Attacks on Round-Reduced Keccak/Xoodoo [PDF]

open access: yes, 2020
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 ...

Cube Attacks and Cube-Attack-Like Cryptanalysis on the Round-Reduced Keccak Sponge Function [PDF]

open access: yes, 2014
International audienceIn this paper, we comprehensively study the resistance of keyed variants of SHA-3 (Keccak) against algebraic attacks. This analysis covers a wide range of key recovery, MAC forgery and other types of attacks, breaking up to 9 rounds

Sponges and Engines: An introduction to Keccak and Keyak

open access: yesIACR Cryptol. ePrint Arch., 2015
In this document we present an introductory overview of the algorithms and design components underlying the Keccac cryptographic primitive and the Keyak encryption scheme for authenticated (session-supporting) encryption. This document aims to familiarize readers with the basic principles of authenticated encryption, the Sponge and Duplex constructions

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.
