Abstract
L'invention concerne un procédé permettant d'effectuer des calculs dans un système mathématique présentant un exposant de Lyapunov, ou présentant un comportement chaotique, lequel procédé consistant à faire varier un paramètre du système. Lorsque ce procédé est employé en cryptographie, notamment, dans un générateur de nombres pseudo aléatoires d'un algorithme de chiffre en continu, dans un système de cryptage par blocs ou dans un système de condensé numérique (HASH/MAC), l'imprévisibilité peut être accrue. Dans un système analogue, un procédé de calcul consiste à multiplier deux nombres et à manipuler au moins l'un des bits les plus significatifs du nombre résultant de la multiplication pour produire une sortie. Un nombre dérivé d'une division de deux nombres peut être utilisé pour dériver une sortie. Dans un système permettant de générer une séquence de nombres, un réseau de compteurs est mis à jour à chaque étape de calcul, une valeur de retenue étant ajoutée à chaque compteur. L'arithmétique en virgule fixe peut être utilisée. L'invention concerne un procédé permettant la détermination d'une valeur d'identification, et un cryptage simultané et/ou un décryptage simultané d'un ensemble de données.
