摘要

The method involves selecting a zone (22) of a memory address space (20) of an information processing system using a selecting unit. A security process (26) is executed on a part of the memory address space during the licit operation of the information processing system, to make the memory address space inaccessible to external processes using an executing unit, where the security process comprises exchange process between determined zones (21, 22) of the memory address space. An independent claim is also included for a device for protecting data and program of an information processing system.
