Ce livre, à travers l’histoire de la cryptographie, décrit les méthodes de chiffrement utilisées selon les époques et leur évolution.
Il est principalement destiné aux enseignants du secondaire (mathématiques ou NSI), et aux candidats au CAPES ou à l’agrégation interne de mathématiques et a pour but de donner un support de cours et des exercices adaptés, selon les chapitres, à différents niveaux, en accord avec les programmes actuels. Le lecteur trouvera, par exemple, des chiffrements « à la main » en Python ou Scratch.

This book provides a survey on different kinds of Feistel ciphers, with their definitions and mathematical/computational properties. Feistel ciphers are widely used in cryptography in order to obtain pseudorandom permutations and secret-key block ciphers. In Part 3, we give results on DES and specific Feistel ciphers.

This book provides a survey on different kinds of Feistel ciphers, with their definitions and mathematical/computational properties. Feistel ciphers are widely used in cryptography in order to obtain pseudorandom permutations and secret-key block ciphers. In Part 1, we describe Feistel ciphers and their variants. We also give a brief story of these ciphers and basic security results. In Part 2, we describe generic attacks on Feistel ciphers. In Part 3, we give results on DES and specific Feistel ciphers. Part 4 is devoted to improved security results. We also give results on indifferentiability and indistinguishability.
