Abstract: The invention relates to a system comprising a non-volatile memory device configured to contain executable code; and a logic device comprising an internal memory and a processor configured to execute the code contained in the non-volatile memory device, the internal memory being located in a first always-on power domain of the logic device, wherein the system is configured to check whether the internal memory contains a code digest Hc, obtain the executable code from the non-volatile memory device, compute a code digest Hc″ of the executable code, and, if the code digest Hc and the code digest Hc″ are identical, execute the executable code. The invention also relates to a corresponding method.
