1. A data processing system comprising: at least one first processor; at least one memory module; at least one memory access controller connected between the at least one first processor and the at least one memory module; at least one external processing module having access to a storage device, the storage device comprising: at least one segment comprising at least one digital information; at least one access condition associated with the at least one segment; at least one first authentication data associated with the at least one segment, the at least one first authentication data allowing for the integrity of the information in the at least one segment to be authenticated; and at least one second authentication data associated with the at least one access condition, the at least one second authentication data allowing for the at least one access condition to be authenticated; and at least one secure memory management module connected to the at least one first processor, the at least one memory module, the at least one external processing module and the at least one memory access controller; wherein the at least one external processing module is configured to request the at least one digital information, the at least one secure memory management module being configured to monitor the request, and, in response to the request, to: authenticate the at least one segment using the first authentication data; authenticate the at least one access condition using the second authentication data; send the at least one access condition to the memory access controller; and load the at least one segment from the at least one storage device to the at least one memory module; wherein the at least one memory access controller is configured to: detect a processor status of the at least one first processor; compare the at least one access condition with the processor status; and provide access to the at least one memory module by the at least one first processor when the processor status satisfies the at least one access condition; and wherein the at least one external processing module is outside a secure zone comprising the at least one first processor, the at least one memory module, the at least one memory access controller, and the at least one secure memory management module.
