INDDIV – Studying novel capabilities of PUF-based IPS diversification
In INDDIV we provide an in-depth examination of new tactics to increase adversarial costs enabled by the new capabilities researched in DEPS. We aim to develop quantitative models of attacker costs, and how they reflect the increasing work factor required to reverse engineer operational software relative to the original approach of having no defenses in place. In this original scenario, the cost of an attack reduces to merely duplicating/replicating the machine, as no costs arise from merely copying the operational. With DEPS protections in place, however, the operational software cannot be copied from one machine to another and be expected to work. If DEPS is successful, adversaries need to reverse engineer the protected code.
