Linear Structures: Applications to Cryptanalysis of Round-Reduced Keccak [PDF]

, 2016
In this paper, we analyze the security of round-reduced versions of the Keccak hash function family. Based on the work pioneered by Aumasson and Meier, and Dinur et al., we formalize and develop a technique named linear structure, which allows ...

The Road from Panama to Keccak via RadioGatún

, 2009
In this presentation, we explain the design choices of Panama [1] and RadioGatun [2], which lead to Keccak [3]. After a brief recall of Panama, RadioGatun and the trail backtracking cost, we focus on three important aspects. First, we explain the role of the belt in the light of differential trails. Second, we discuss the relative advantages of a block

Keccak [PDF]

, 2015
In October 2012, the American National Institute of Standards and Technology (NIST) announced the selection of Keccak as the winner of the SHA-3 Cryptographic Hash Algorithm Competition [10,11]. This concluded an open competition that was remarkable both

Optimized Implementations of Keccak, Kyber, and Dilithium on the MSP430 Microcontroller

Transactions on Cryptographic Hardware and Embedded Systems
Post-Quantum cryptography (PQC) typically requires more memory and computational power than conventional public-key cryptography. Until now, most active research in PQC optimization for embedded devices has focused on 32-bit and 64-bit ARM architectures,

Key-Recovery Attacks on Full Kravatte

IACR Transactions on Symmetric Cryptology, 2018
This paper presents a cryptanalysis of full Kravatte, an instantiation of the Farfalle construction of a pseudorandom function (PRF) with variable input and output length.

SDN Controller Selection and Secure Resource Allocation

IEEE Access
Software Defined Networking (SDN) has emerged as a promising paradigm for network management. However, in energy-effective task scheduling and security, the centralized control architecture of SDN brings challenges.

Farfalle: parallel permutation-based cryptography

IACR Transactions on Symmetric Cryptology, 2017
In this paper, we introduce Farfalle, a new permutation-based construction for building a pseudorandom function (PRF). The PRF takes as input a key and a sequence of arbitrary-length data strings, and returns an arbitrary-length output.

Improved Preimage Attacks on Round-Reduced Keccak-384/512 [PDF]

, 2023
This paper provides improved preimage analysis on round-reduced Keccak-384/512. Unlike low-capacity versions, Keccak-384/512 outputs from two parts of its state: an entire 320-bit plane and a 64/192-bit truncation of a second plane.
