Abstract

Méthode cryptographique de vérification des données Procédé de comparaison mis en œuvre par au moins un appareil (A ; B), entre un premier et deuxième ensemble de données, en vue notamment de déterminer si ces deux ensembles de données sont identiques, ce procédé ne nécessitant pas la présence de ces deux ensembles de données sur l’appareil, et comportant les étapes suivantes : le mélange d’un nombre, dit nombre de mélange, au premier ensemble de données, à l’aide d’une fonction de mélange (105 ; 405), pour obtenir des données mélangées, le hachage des données mélangées à l’aide d’une fonction de hachage (106 ; 406), et la comparaison du haché ainsi obtenu à l’étape b) avec un troisième ensemble de données supposé être le haché du deuxième ensemble de données mélangé au même nombre de mélange que celui utilisé à l’étape a) et avec la même fonction de mélange (105 ; 405). Figure pour l’abrégé : Fig. 2
