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 ...

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.

Cube-like Attack on Round-Reduced Initialization of Ketje Sr

open access: yesIACR Transactions on Symmetric Cryptology, 2017
This paper studies the Keccak-based authenticated encryption (AE) scheme Ketje Sr against cube-like attacks. Ketje is one of the remaining 16 candidates of third round CAESAR competition, whose primary recommendation is Ketje Sr.

Differential Trail Search in Cryptographic Primitives with Big-Circle Chi:

open access: yesIACR Transactions on Symmetric Cryptology, 2022
Proving upper bounds for the expected differential probability (DP) of differential trails is a standard requirement when proposing a new symmetric primitive.

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 ...

Tanda tangan Digital Menggunakan Algoritme Keccak dan RSA

open access: yesJurnal Nasional Teknik Elektro dan Teknologi Informasi, 2016
Just like conventional signatures, digital signatures can be used to prove the authenticity of a document in digital form. In addition, digital signatures can also be used to prove the validity of the author of the document, so that the author of the ...

A Tale of Snakes and Horses: Amplifying Correlation Power Analysis on Quadratic Maps

open access: yesTransactions on Cryptographic Hardware and Embedded Systems, 2023
We study the success probabilities of two variants of Correlation Power Analysis (CPA) to retrieve multiple secret bits. The target is a permutation-based symmetric cryptographic construction with a quadratic map as an S-box. More precisely, we focus on

An Economic Analysis of Difficulty Adjustment Algorithms in Proof‐of‐Work Blockchain Systems

open access: yesInternational Economic Review, Volume 67, Issue 1, Page 259-285, February 2026.
ABSTRACT We study the stability of cryptocurrency systems through difficulty adjustment. Bitcoin's difficulty adjustment algorithm (DAA) exhibits instability when the reward elasticity of the hash rate is high, implying that a sharp price reduction could disrupt the current Bitcoin system.
