              <p>Le problèmeLearning With Errors (LWE) est algorithmiquement difficile pour des instances aléatoires. Il a été introduit par Oded Regev en 2005 et, depuis lors, il s'est avéré très utile pour construire des primitives cryptographiques, pour assurer la confidentialité de l'information. Dans ce chapitre, nous présenterons le problème LWE et illustrerons sa richesse, en décrivant des schémas de chiffrement avancés pouvant être prouvés au moins aussi sûrs que LWE est difficile. Nous rappellerons le concept fondamental de chiffrement, puis nous nous focaliserons sur les notions de chiffrement fondé sur l'identité et de chiffrement par attributs.</p>
