Wavelet: Code-based postquantum signatures with fast verification on microcontrollers
Gustavo Banegas, Thomas Debris-Alazard, Milena Nedeljković +1
This work presents the first full implementation of Wave, a postquantum code-based signature scheme. We define Wavelet, a concrete Wave scheme at the 128-bit classical security lev…
Classical and Quantum algorithms for generic Syndrome Decoding problems and applications to the Lee metric
André Chailloux, Thomas Debris-Alazard, Simona Etinski
The security of code-based cryptography usually relies on the hardness of the syndrome decoding (SD) problem for the Hamming weight. The best generic algorithms are all improvement…
On the hardness of code equivalence problems in rank metric
Alain Couvreur, Thomas Debris-Alazard, Philippe Gaborit
In the recent years, the notion of rank metric in the context of coding theory has known many interesting developments in terms of applications such as space time coding, network c…
Ternary Syndrome Decoding with Large Weight
Rémi Bricout, André Chailloux, Thomas Debris-Alazard +1
The Syndrome Decoding problem is at the core of many code-based cryptosystems. In this paper, we study ternary Syndrome Decoding in large weight. This problem has been introduced i…
Wave: A New Family of Trapdoor One-Way Preimage Sampleable Functions Based on Codes
Thomas Debris-Alazard, Nicolas Sendrier, Jean-Pierre Tillich
We present here a new family of trapdoor one-way Preimage Sampleable Functions (PSF) based on codes, the Wave-PSF family. The trapdoor function is one-way under two computational a…
Two attacks on rank metric code-based schemes: RankSign and an Identity-Based-Encryption scheme
Thomas Debris-Alazard, Jean-Pierre Tillich
RankSign [GRSZ14a] is a code-based signature scheme proposed to the NIST competition for quantum-safe cryptography [AGHRZ17] and, moreover, is a fundamental building block of a new…
