A Power-Aware Malware-Detection Framework on Mobile Handheld Devices

Abstract: Mobile users of computation and communication services have been rapidly adopting battery-powered mobile handhelds, such as PocketPCs? and SmartPhones? , for their work. However, the limited battery-lifetime of these devices restricts their portability and applicability, and this weakness can be exacerbated by mobile malware targeting depletion of battery energy. Such malware are usually difficult to detect and prevent, and frequent outbreaks of new malware variants also reduce the effectiveness of commonly-seen signature-based detection. To alleviate these problems, we propose a power-aware malware-detection framework that monitors, detects, and analyzes previously unknown energy-depletion threats.
