Cryptanalysis of LowMC instances using single plaintext/ciphertext pair
Serge Vaudenay, Subhadeep Banik, Fatma Betül Durak, Khashayar Barooti
Arguably one of the main applications of the LowMC family ciphers is in the post-quantum signature scheme PICNIC. Although LowMC family ciphers have been studied from a cryptanalytic point of view before, none of these studies were directly concerned with ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2020Cryptanalysis of ForkAES
Forkciphers are a new kind of primitive proposed recently by Andreeva et al. for efficient encryption and authentication of small messages. They fork the middle state of a cipher and encrypt it twice under two smaller independent permutations. Thus, forkci ...
2019GIFT: A Small Present Towards Reaching the Limit of Lightweight Encryption
In this article, we revisit the design strategy of PRESENT, leveraging all the advances provided by the research community in construction and cryptanalysis since its publication, to push the design up to its limits. We obtain an improved version, named GI ...
2017DES S-box generator
Serge Vaudenay, Lauren De Meyer
The Data Encryption Standard (DES) is a cryptographic algorithm, designed by IBM, that was selected to be the national standard in 1977 by the National Bureau of Standards. The algorithm itself was entirely published but the design criteria were kept secre ...
Taylor & Francis Inc2016Algebraic Cryptanalysis of Deterministic Symmetric Encryption
Deterministic symmetric encryption is widely used in many cryptographic applications. The security of deterministic block and stream ciphers is evaluated using cryptanalysis. Cryptanalysis is divided into two main categories: statistical cryptanalysis and ...
EPFL2015Efficient Recursive Diffusion Layers for Block Ciphers, and Hash Functions
Many modern block ciphers use maximum distance separable (MDS) matrices as the main part of their diffusion layers. In this paper, we propose a very efficient new class of diffusion layers constructed from several rounds of Feistel-like structures whose ro ...
