Method for the authentification or certification of at least one bit of information stored in the memory of an electronic carrier, especially a replaceable and portable one such as a card
Abstract
Abstract Translated from French Le procédé consiste, pour certifier une information (I) enregistrée dans une mémoire (M) d'une carte (C), à faire exécuter, par des circuits de traitement (TC) de la carte (C), un programme (P) qui prend en compte l'adresse de l'information (I) dans la mémoire (M), adresse qui est communiquée à la carte (C) depuis l'extérieur. L'exécution du programme (P) aboutit à un résultat (R) qui est comparé avec une résultat (R') calculé de façon identique par un appareil de transaction (1) auquel est connectée la carte (C). L'invention s'applique notamment aux cartes de crédit. The method consists, to certify information (I) recorded in a memory (M) of a card (C), to execute, by processing circuits (TC) of the card (C), a program (P) which takes into account the address of the information (I) in the memory (M), address which is communicated to the card (C) from the outside. The execution of the program (P) results in a result (R) which is compared with a result (R ') calculated identically by a transaction device (1) to which the card (C) is connected. The invention is particularly applicable to credit cards.
