Abstract
A hardware malware profiling and detection system is disclosed. In embodiments, the system includes a primary (e.g., trusted) system including template processors and hardware sensors. The template processors submit input vectors to the primary system and characterize the system response via power trace data collected by the hardware sensors. Based on the input vectors and power trace data, the template processors generate system templates and derive system challenges therefrom. The template processors submit the system challenges to a remote system under test and characterize the remote system response in real time via identical remote hardware sensors. The template processors correlate the real-time remote system response data with the system templates corresponding to the issued challenges to detect system anomalies or malware within the remote system or its components.
