Abstract
An executable module includes a dynamic data area that contains all data that may be changed by execution of the executable module. A header in the module includes a start address and an end address for the dynamic data area. The executable module is loaded in a memory. An alternate memory area is allocated in the memory. The dynamic data area is copied to the alternate memory area. The memory is mapped so that execution of the executable module modifies exactly one of the dynamic data area and the alternate memory area. A hash value is computed for the executable module. The hash value includes exactly one of the dynamic data area and the alternate memory area. The unmodified memory area is copied to the modified memory area and the hash value is recomputed to re-establish the executable module in a known state.
