Title
(EN) METHOD FOR CALCULATING HASHING OF A MESSAGE IN A DEVICE COMMUNICATING WITH A SMART CARD
(FR) PROCEDE PERMETTANT DE CALCULER LE HACHAGE D'UN MESSAGE DANS UN DISPOSITIF COMMUNIQUANT AVEC UNE CARTE A PUCE
Abstract
(EN)
The invention is a method for calculating hashing of a message in a device communicating with a smart card, said device and said smart card storing the same hash function, the message comprising data blocks including secret data and other data, secret data being only known by the smart card, characterized in that the calculation of the hash of the secret data is performed in the smart card and the calculation of the hash of all or part of the other data is performed in the device, and in that, the intermediate result is transmitted from the device to the card, or inversely, depending on whether the hash calculation of the hash of a data has to be performed by the smart card or the device.
(FR)
La présente invention concerne un procédé permettant de calculer le hachage d'un message dans un dispositif communiquant avec une carte à puce. Ce dispositif et cette carte à puce contiennent la même fonction de hachage. Le message contient des blocs de données contenant des données secrètes ainsi que d'autres données; les données secrètes étant connues de la seule carte à puce. Le procédé décrit dans cette invention se caractérise par l'exécution du calcul du hachage des données secrètes, dans la carte à puce, et par l'exécution du calcul du hachage de toutes ou partie des autres données, dans le dispositif. Le résultat intermédiaire est transmis par le dispositif à la carte, ou inversement, selon que le calcul du hachage des données doit être exécuté par la carte à puce ou le dispositif.
