The team participates in the “Calcul formel, arithmétique, protection de l'information” research pole of the GDR-IM (CNRS Research Groupon Mathematical Computer Science). The team is a member of the “Arithmétique”, “Calcul formel” and “Codage et Cryptographie” working groups.
ANR CATREL (Cribles: Améliorations Théoriques et Résolution Effective du Logarithme discret)
Participants : Razvan Barbulescu, Cyril Bouvier, Jérémie Detrey, Pierrick Gaudry, Hamza Jeljeli, Emmanuel Thomé [contact] , Marion Videau, Paul Zimmermann.
The CATREL proposal has been accepted in ANR “programme Blanc” in 2012. This project involves Caramel as a leading team, in cooperation with two other partners which are Inria project-team GRACE (Inria Saclay, LIX, École polytechnique), and the Arith team of the LIRMM Laboratory (Montpellier). The project targets the algorithms for solving the discrete logarithm problem in finite fields, using the Number Field Sieve and the Function Field Sieve algorithms. Actual work on the CATREL project started in January 2013. Three meetings have taken place already: in Nancy on Dec. 14th, 2012 (kick-off), in Palaiseau on June 19, 2013, and in Monpellier on November 12-13, 2013.
GDR-IM supported travel for PhD students
Hamza Jeljeli collaborated with Bastien Vialla from LIRMM, Montpellier to integrate RNS-based code in mp and Cado-nfs . This collaboration was funded by the GDR-IM program “visite de doctorants".
