Title
(EN) GENERATING A PSEUDORANDOM NUMBER SEQUENCE
(FR) GÉNÉRATION D'UNE SÉQUENCE DE NOMBRES PSEUDO-ALÉATOIRE
Abstract
(EN)
A method of generating a pseudorandom number sequence for encrypting/decrypting data. A seed number is iteratively modified. For each iterative modification of the seed number, a plurality of sequence numbers are generated for the pseudorandom number sequence based on that iteration of the seed number. Thus, a plurality of sequence numbers are obtained during each iteration of modifying a seed number.

L'invention concerne un procédé de génération d'une séquence de nombres pseudo-aléatoire pour chiffrer/déchiffrer des données. Un nombre graine est modifié de manière itérative. Pour chaque modification itérative du nombre graine, une pluralité de nombres de séquence sont générés pour la séquence de nombres pseudo-aléatoire sur la base de cette itération du nombre graine. Ainsi, une pluralité de nombres de séquence sont obtenus au cours de chaque itération de modification d'un nombre graine.
