Algorithmes de calcul de logarithmes discrets dans les corps finis

Computing discrete logarithms is a fundamental task for public key cryptanalysis. Themere existence of a subexponential algorithm for this purpose is not sufficient to definitely ruleon the security level provided by some cryptosystem. Assessing state-of-the-art cryptanalysiscalls for a thorough evaluation process. This dissertation contributes to such an evaluation.In particula...

Fast Algorithms for Towers of Finite Fields and Isogenies. (Algorithmes Rapides pour les Tours de Corps Finis et les Isogénies)

In this thesis we apply techniques from computer algebra and languagetheory to speed up the elementary operations in some specific towers of finitefields. We apply our construction to the problem of computing isogeniesbetween elliptic curves and obtain faster (both asymptotically and in practice)variants of Couveignes’ algorithm.The document is divided in four parts. In Part...
