Title (EN) METHOD FOR PROTECTING SENSITIVE DATA ON A STORAGE DEVICE HAVING WEAR LEVELING
(FR) PROCÉDÉ POUR PROTÉGER DES DONNÉES SENSIBLES SUR UN DISPOSITIF DE STOCKAGE AYANT UNE GESTION DE L'USURE
Abstract:
(EN) Disclosed is a method for protecting sensitive data in a storage device having wear leveling. In the method, a write command, with an associated sensitive write signal indicating that sensitive data is associated with the write command, is received. The sensitive data is further associated with at least one address pointing to a storage location within an initial physical storage block. The write command is executed by writing to at least one storage location within an available physical storage block, pointing the at least one address to the at least one storage location within the available physical storage block, and erasing the initial physical storage block to complete execution of the write command.
(FR) L'invention concerne un procédé pour protéger des données sensibles dans un dispositif de stockage ayant une gestion de l'usure. Dans le procédé, une commande d'écriture, avec un signal d'écriture sensible associé indiquant que des données sensibles sont associées à la commande d'écriture, est reçue. Les données sensibles sont en outre associées à au moins une adresse pointant sur un emplacement de stockage dans un bloc de stockage physique initial. La commande d'écriture est exécutée par l'écriture sur au moins un emplacement de stockage dans un bloc de stockage physique disponible, le pointage de ladite adresse sur ledit emplacement de stockage dans le bloc de stockage physique disponible, et l'effacement du bloc de stockage physique initial pour achever l'exécution de la commande d'écriture.
