State of the Art in Lightweight Symmetric Cryptography
Alex Biryukov,Léo Perrin +1 more
TL;DR: The different implementation constraints that a “lightweight” algorithm is usually designed to satisfy in both the software and the hardware case are discussed and a clearer distinction between two subsets of lightweight cryptography is suggested.
Design Strategies for ARX with Provable Bounds: Sparx and LAX
Daniel Dinu,Léo Perrin,Aleksei Udovenko,Vesselin Velichkov,Johann Großschädl,Alex Biryukov +5 more
- 04 Dec 2016
TL;DR: In this article, the authors proposed the long trail design strategy (LTS), a dual of the wide-trail design strategy that is applicable (but not limited) to ARX constructions, which advocates the use of large S-boxes together with sparse linear layers.

Triathlon of Lightweight Block Ciphers for the Internet of Things.
TL;DR: In this article, the authors introduce an open framework for the benchmarking of lightweight block ciphers on a multitude of embedded platforms, allowing a user to define a custom "figure of merit" according to which all evaluated candidates can be ranked.
Feistel Structures for MPC, and More
Martin R. Albrecht,Lorenzo Grassi,Léo Perrin,Sebastian Ramacher,Christian Rechberger,Dragos Rotaru,Dragos Rotaru,Arnab Roy,Markus Schofnegger +8 more
- 23 Sep 2019
TL;DR: In this article, a family of PRP/PRF generalizations of the well-known Feistel design approach followed in a previously proposed application specific design -MiMC is presented.

Saturnin: a suite of lightweight symmetric algorithms for post-quantum security
Anne Canteaut,Sébastien Duval,Gaëtan Leurent,María Naya-Plasencia,Léo Perrin,Thomas Pornin,André Schrottenloher +6 more
- 22 Jun 2020
TL;DR: Saturnin-CTR-Cascade as discussed by the authors is an authenticated cipher using the counter mode and a separate MAC, which requires two passes over the data but its implementation does not require the inverse block cipher.
