Abstract

Un procédé de vérification de l'intégrité de données mémorisées dans une mémoire (6) d'un appareil électronique (2) comprend les étapes suivantes : - réception, par l'appareil électronique (2), d'au moins une partie de programme (Pn), d'une pluralité d'éléments de diversification (ri) et de condensats (Hn,i) respectivement associés auxdits éléments de diversification ; - mémorisation desdits éléments de diversification (ri) et desdits condensats (Hn,i) dans une entité électronique (10) équipant l'appareil électronique (2) et distincte de ladite mémoire (6) ; - vérification, par l'entité électronique (10) et au moyen d'un condensat donné (Hn,i) parmi lesdits condensats, de l'intégrité d'une partie au moins de la mémoire (6) mise à jour au moyen du programme (Pn). Une entité électronique associée (10) et un appareil (2) comprenant une telle entité électronique (10) sont également présentés.A method for verifying the integrity of data stored in a memory (6) of an electronic apparatus (2) comprises the steps of: - receiving, by the electronic apparatus (2), at least one program part (Pn), a plurality of diversification elements (ri) and condensates (Hn, i) respectively associated with said diversification elements; storage of said diversification elements (ri) and said condensates (Hn, i) in an electronic entity (10) equipping the electronic apparatus (2) and distinct from said memory (6); - verification, by the electronic entity (10) and by means of a given condensate (Hn, i) among said condensates, the integrity of at least a portion of the memory (6) updated by means of program (Pn). An associated electronic entity (10) and an apparatus (2) including such an electronic entity (10) are also presented.
