9 December 2001

We show that it is indeed possible to construct a practical signature scheme based on Niederreiter’s variant [12] on the McEliece cryptosystem. Expand

Security Bounds for the Design of Code-Based Cryptosystems

M. Finiasz, N. Sendrier

ASIACRYPT
2 December 2009

Code-based cryptography is often viewed as an interesting "Post-Quantum" alternative to the classical number theory cryptography. Expand

A Family of Fast Syndrome Based Cryptographic Hash Functions

D. Augot, M. Finiasz, N. Sendrier
Computer Science
Mycrypt
28 September 2005

We present a family of secure hash functions, whose security is directly related to the syndrome decoding problem from the theory of error-correcting codes. Expand

We focus on the problem of recovering the length and synchronization of a linear block code from an intercepted bitstream. Expand

Exhaustive search for small dimension recursive MDS diffusion layers for block ciphers and hash functions

D. Augot, M. Finiasz
Mathematics, Computer Science
IEEE International Symposium on Information…
15 May 2013

This article presents a new algorithm to find MDS matrices that are well suited for use as a diffusion layer in lightweight block ciphers, yielding an efficient 80-bit diffusion layer with maximal branch number. Expand

A Fast Provably Secure Cryptographic Hash Function

TCHo: A Hardware-Oriented Trapdoor Cipher

J. Aumasson, M. Finiasz, W. Meier, S. Vaudenay
Mathematics, Computer Science
ACISP
2 July 2007

This paper improves the Finiasz-Vaudenay construction of \(\mathcal{TCH}o\), a hardware-oriented public-key cryptosystem, whose security relies on the hardness of finding a low-weight multiple of a given polynomial, and on the decoding of certain noisy cyclic linear codes. Expand
