Abstract

L'invention concerne un dispositif sécurisé (200) et, plus particulièrement, des systèmes, des dispositifs et des procédés de réduction de la consommation d'énergie du dispositif sécurisé (200) en limitant la quantité de mémoire volatile sécurisée qui doit être alimentée par une batterie (102). Dans un mode d'alimentation de transport, les données sensibles mémorisées à l'origine dans une mémoire volatile (204) sont sauvegardées dans un format chiffré dans une mémoire non volatile (202), de sorte qu'aucune ou seulement une petite zone de la mémoire volatile sécurisée (204) doive être retenue et alimentée par la batterie (102) pour préserver les clés cryptographiques qui sont utilisées pour sauvegarder et récupérer les données sensibles. Ce dispositif sécurisé (200) est appliqué dans des applications à sécurité élevée telles que des terminaux financiers sécurisés.
