The subject of this thesis is the design and implementation of efficient algorithms for some basic operations in computer algebra, as well as their applications to related fields, such as computational number theory and cryptography. The first part of the text is dedicated to basic algorithms on univariate polynomials. The tool which we use systematically is a constructive version of Tellegen's transposition principle, which makes it possible to obtain new algorithms for the problems of multipoint evaluation and interpolation (in various polynomial bases and for various families of evaluation points), as well as a theorem of equivalence between the complexities of these two problems. The second part is devoted to fast computation with algeb...
