ArtProtect: Blockchain and NFC‐based anti‐counterfeit system for physical art
IET Blockchain, Volume 4, Issue 4, Page 423-442, December 2024.An anti‐counterfeiting system for physical art based on Ethereum blockchain and near‐field communication technology is proposed and implemented. The system leverages the use of Ethereum smart contracts and inter‐planetary file system to store artworks’ certificate of authenticity, and display them in a mobile app called ArtProtect.

New techniques for trail bounds and application to differential trails in Keccak
IACR Transactions on Symmetric Cryptology, 2017 We present new techniques to efficiently scan the space of high-probability differential trails in bit-oriented ciphers. Differential trails consist in sequences of state patterns that we represent as ordered lists of basic components in order to arrange

Higher-Order Side-Channel Protected Implementations of KECCAK
2017 Euromicro Conference on Digital System Design (DSD), 2017 The efficient protection of security critical devices against side-channel analysis attacks is a fundamental need in the age of Internet of Things and ubiquitous computing. In this work, we introduce a configurable hardware design of KECCAK (SHA-3) which can be tailored to fulfill the needs of a wide range of different applications.

Toward designing a lightweight RFID authentication protocol for constrained environments
IET Communications, Volume 18, Issue 14, Page 846-859, August 2024.Our article investigates the vulnerabilities of lightweight RFID authentication schemes, namely LRSAS+ and LRARP+, and proposes an enhanced version leveraging the χper$\chi per$ function to address their weaknesses. Through formal analysis and comparison with contemporary systems, we demonstrate that the improved scheme achieves robust security while ...

Algebraic-differential analysis of Keccak
, 2016 In this thesis, we analyze the cryptographic sponge function family Keccak - the winner of the SHA-3 Cryptographic Hash Standard competition. Firstly, we explore how higher order differentials can be used to forge a tag in a parallelizable MAC function ...

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

MILP-aided Cube-attack-like Cryptanalysis on Keccak Keyed Modes [PDF]
, 2018 Cube-attack-like cryptanalysis was proposed by Dinur et al. at EUROCRYPT 2015, which recovers the key of Keccak keyed modes in a divide-and-conquer manner. In their attack, one selects cube variables manually, which leads to more key bits involved in the
