Title (EN) A METHOD TO COMPENSATE BY A SERVER A CLOCK DEVIATION OF A CARD
(FR) PROCÉDÉ DE COMPENSATION, AU MOYEN D'UN SERVEUR, D'UN ÉCART D'HORLOGE D'UNE CARTE
Abstract:
(EN) This invention relates to a method to compensate by a server a clock deviation of a card i by maintaining a time base Tbase (i) synchronized with card i, the method comprising the steps of: receiving (300) at a time TS a dynamic card verification dCVV code value generated by card i; providing (301) a set of at least two dCVV code corresponding to two successive dCVV time periods; if (302) the dCVV code received from card i corresponds to one of the dCVV codes of the provided set but is different from the reference dCVV code, determine (303, 304, 305) the minimum possible timing drift Min_td between the time base maintained by the server for the card and the time base Tbase(i) of the card; updating (306) time base Tbase(i) by addition of a time drift correction equal to the minimum possible time drift Min_td.
(FR) La présente invention concerne un procédé permettant de compenser, au moyen d'un serveur, un écart d'horloge d'une carte ipar maintien d'une base de tempsTbase (i) synchronisée avec la carte i, le procédé comprenant les étapes consistant à : recevoir (300), à un instant TS, une valeur de code de vérification de carte dynamique dCVV générée par la carte i ; fournir (301) un ensemble d'au moins deux codes de dCVV correspondant à deux périodes de temps successives de dCVV ; si (302) le code de dCVV reçu de la carte i correspond à l'un des codes de dCVV de l'ensemble fourni mais est différent du code de référence de dCVV, déterminer (303, 304, 305) la dérive temporelle minimale possible Min_td entre la base de temps maintenue par le serveur pour la carte et la base de temps Tbase(i) de la carte ; mettre à jour (306) la base de temps Tbase(i) par addition d'une correction de dérive temporelle égale à la dérive temporelle minimale possible Min_td.
