Our work [6], in collaboration with J. Fried and N. Heninger from the University of Pennsylvania, describing a kilobit discrete logarithm computation for a trapdoored prime number has been published in Eurocrypt 2017.

A paper detailing the implementation of the ECM factoring algorithm on the Kalray MPPA-256 many-core processor, written as a collaboration between Jérémie Detrey and Pierrick Gaudry from CARAMBA, and Masahiro Ishii, Atsuo Inomata, and Kazutoshi Fujikawa from NAIST (Nara, Japan), was published in IEEE Transaction on Computers [2].

In [39], the notions of Square, saturation, integrals, multisets, bit patterns and tuples cryptanalysis are revised. A new Slice & Fuse paradigm to better exploit multiset type properties of block ciphers is proposed. With this refined analysis, we improve the best bounds proposed in such contexts against the following block ciphers: Threefish, Prince, Present and Rectangle.

In [3], we improve the existing impossible-differential attacks against Rijndael-160 and Rijndael-224.

Our work [10] about the computational power of the Measurement-based Quantum Computation model, written by Luc Sanselme and Simon Perdrix (from the CARTE team at LORIA), has appeared.
