This note was written in 1997 after a talk I gave at the seminaire de complexite et cryptographie at the ´ Ecole Normale Superieure After it was rejected at crypto97 I forgot it until a few… (More)

The heart of Schoof's algorithm for computing the cardinality m of an elliptic curve over a finite field is the computation of m modulo small primes l. Elkies and Atkin have designed practical… (More)

We study the action of modular correspondences in the p- adic neighborhood of CM points. We deduce and prove two stable and efficient p-adic analytic methods for computing singular values of modular… (More)

We give a method for efficiently computing isomorphisms between towers of Artin-Schreier extensions over a finite field. We find that isomorphisms between towers of degree p over a fixed field Fq can… (More)

We construct two new families of basis for finite field extensions. Bases in the first family, the so-called elliptic bases, are not quite normal bases, but they allow very fast Frobenius… (More)

We show how the study of the geometry of the nine flex tangents to a cubic produces pseudo-parameterizations, including the ones given by Icart, Kammerer, Lercier, Renault and Farashahi, and… (More)

Computing l-isogenies between elliptic curves defined over a finite field Fq of small characteristic is of some importance for the computation of the cardinalities of elliptic curves using… (More)

We propose a formal model for situated and reactive multi-agent systems based on correlated discrete random walks. In order to study this model, we construct a continuous approximation ending up on… (More)

We report on current work on parameterization of low genera algebraic curves. For example, we prove that for $q$ a prime power that is large enough and prime to 6, a fixed positive proportion of all… (More)
