Energy attacks and defense techniques for wireless systems.

ABSTRACTThis paper addresses the energy attacks towards wireless systems, where energy is the most critical constraint to lifetime and reliability. We for the first time propose a hardware-based energy attack, namely energy hardware Trojans (HTs), which can be well hidden in the wireless systems and trigger ultra-high energy increases at runtime. Then, we develop a non-destructive HT detection approach to identify the energy attack by remotely sampling the power profiles of the system and characterizing the gate-level temperatures. Our evaluation results on ISCAS benchmarks indicate the effectiveness of the proposed energy attacks and defense techniques.
