Abstract
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.
