Modern processor systems are equipped with on-chip or on-board power controllers. In this paper, the authors examine the challenges and pitfalls in architecting such dynamic power management control systems. A key question that they pose is: How to ensure that such managed systems are \"Energy-secure\" and how to pursue pre-silicon modeling to ensure such security? In other words, they address the robustness and security issues of such systems. They discuss new advances in energy-secure power management, starting with an assessment of potential vulnerabilities in systems that do not address such issues up front.
