The present invention describes a system and a method for securely loading digital information from a storage device into a memory module in a data processing system, said data processing system comprising at least one storage device, one memory module and at least one processor, said data processing system further comprising a memory access controller module connected between the processor and the memory module, and a secure memory management module connected to the processor, the memory module, the storage device and the memory access controller. Requests by the processor for data are passed to the secure memory management module, which loads the data from the storage device to the memory module and configures the memory access controller such that the processor will have access to the data.

La présente invention concerne un système et un procédé pour charger de façon sécurisée des informations numériques à partir dun dispositif de stockage dans un module de mémoire se trouvant dans un système de traitement de données, ledit système de traitement de données comprenant au moins un dispositif de stockage, un module de mémoire et au moins un processeur, ledit système de traitement de données comprenant en outre un module de commande daccès à la mémoire connecté entre le processeur et le module de mémoire, et un module de gestion de mémoire sécurisé connecté au processeur, le module de mémoire, le dispositif de stockage et lunité de commande daccès à la mémoire. Des demandes de données provenant du processeur sont transmises au module de gestion de mémoire sécurisé, qui charge les données du dispositif de stockage dans le module de mémoire et configure la commande daccès à la mémoire de telle sorte que le processeur puisse avoir accès aux données.
