Computing change of level and isogenies between abelian varieties
Antoine Dequay, David Lubicz
Let be integers such that . In this paper, we present an efficient change of level algorithm that takes as input a marked abelia…
Quantifying Jitter Transfer for Differential Measurement: Enhancing Security of Oscillator-Based TRNGs
David Lubicz, Maciej Skorski
The aim of this paper is to describe a way to improve the reliability of the measurement of the statistical parameters of the phase noise in a multi-ring oscillator-based TRNG. Thi…
Computing separable isogenies in quasi-optimal time
David Lubicz, Damien Robert
Let be an abelian variety of dimension together with a principal polarization defined over a field . Let be an odd integer prime to the…
Semi-simplified modulo of semi-stable representations: an algorithmic approach
Xavier Caruso, David Lubicz
The aim of this paper is to present an algorithm the complexity of which is polynomial to compute the semi-simplified modulo of a semi-stable $\Q_p$-representation of the absol…
Linear Algebra over Z_p[[u]] and related rings
Xavier Caruso, David Lubicz
Let R be a complete discrete valuation ring, S=R[[u]] and n a positive integer. The aim of this paper is to explain how to compute efficiently usual operations such as sum and inte…
Computing isogenies between abelian varieties
David Lubicz, Damien Robert
We describe an efficient algorithm for the computation of separable isogenies between abelian varieties represented in the coordinate system given by algebraic theta functions. Let…
