Direct Construction of Recursive MDS Diffusion Layers using Shortened BCH Codes
Daniel Augot, Matthieu Finiasz
MDS matrices allow to build optimal linear diffusion layers in block ciphers. However, MDS matrices cannot be sparse and usually have a large description, inducing costly software/…
Exhaustive Search for Small Dimension Recursive MDS Diffusion Layers for Block Ciphers and Hash Functions
Daniel Augot, Matthieu Finiasz
This article presents a new algorithm to find MDS matrices that are well suited for use as a diffusion layer in lightweight block ciphers. Using an recursive construction, it is po…
Methods for the Reconstruction of Parallel Turbo Codes
Mathieu Cluzeau, Matthieu Finiasz, Jean-Pierre Tillich
We present two new algorithms for the reconstruction of turbo codes from a noisy intercepted bitstream. With these algorithms, we were able to reconstruct various turbo codes with…
NP-completeness of Certain Sub-classes of the Syndrome Decoding Problem
Matthieu Finiasz
The problem of Syndrome Decoding was proven to be NP-complete in 1978 and, since then, quite a few cryptographic applications have had their security rely on the (provable) difficu…
