Security has become an important characteristic for many real-time systems. Due to the lack of enough and stable energy supply in battery-powered embedded systems, one of the foremost challenges is the mismatch between energy and performance requirements of security processing. In this paper, we propose a security-aware and energy-efficient scheduling algorithm that aims at reducing energy consumption while ensuring the real-time and security requirements. Based on the feedback control theory, we employ a feedback unit to keep track of the CPU utilization and manage the security level dynamically. Simulation results show the effectiveness and efficiency of the proposed algorithm. © 2012 Springer Science+Business Media.
