ABSTRACT:
Restricting execution by a computing device of instructions within an application program. The application program is modified such that execution of the selected instructions is dependent upon a corresponding expected state of one or more hardware components in the computing device. In an embodiment, the application program is modified to place the hardware components in the expected states prior to execution of the corresponding selected instructions. Creating the dependency on the hardware components prevents the unintended or malicious execution of the selected instructions.
