Ballistic Missile Defense Innovative Anti-Tamper Techniques

Adversaries reverse engineer weapons systems to replicate a system's advanced capabilities or discover its weaknesses. Many of these critical systems are real-time systems. The restrictions of real-time have a significant impact on the implementation of anti-tamper technology. This work will build on our prototype for transforming source code and machine code to add state-of-the-art protection against reverse engineering. An optimizing planner will determine how to best apply the defensive transformations in order to maximize the degree of protection without violating the real-time constraints. We will also investigate transforms that are directed specifically toward protecting architectural features of real-time platforms.
