Abstract
Trusted execution of a self-modifying executable is facilitated. An attempt to access a data portion of a self-modifying executable during execution of the self-modifying executable is detected. The self-modifying executable includes the data portion, for storing data to be accessed during execution of the self-modifying executable, and an instruction portion including instructions for execution of the self-modifying executable. The attempt to access the data portion is retargeted to a separate portion of memory space that is separate from another portion of memory space in which the self-modifying executable is loaded for execution. Meaningful measurability of the integrity of the self-modifying executable is thereby provided.
