Abstract
Systems and methods for relocating executable instructions to arbitrary locations are described, in which the relocation of the instructions may be arbitrary or random, and may operate on groups of instructions or individual instructions. Such relocation may be achieved through hardware or software, and may use a virtual machine, software dynamic translators, interpreters, or emulators. Instruction relocation may use or produce a specification governing how to relocate the desired instructions. Randomizing the location of instructions provides defenses against a variety of security attacks. Such systems and methods may provide many advantages over other instruction relocation techniques, such as low runtime overhead, no required user interaction, applicability post-deployment, and the ability to operate on arbitrary executable programs.
