We approach the emerging area of energy efficient, secure real-time embedded systems design. Many modern embedded systems have to fulfill strict security constraints and are often required to meet stringent deadlines in different operation modes, where the number and nature of active tasks vary (dynamic task sets). In this context, the use of dynamic voltage/frequency scaling (DVFS) techniques and onboard field-programmable gate array (FPGA) co-processors offer new dimensions for energy savings and performance enhancement. We propose a novel design framework that provides the best security protection consuming the minimal energy for all operation modes of a system. Extensive experiments demonstrate the efficiency of our techniques.
