Abstract:
Disclosed herein are methods, systems, and devices for identifying computational operations based on power measurements. Disclosed herein are systems that may include a phase measurement unit configured to generate a first measurement based on a power signal, the first measurement characterizing a phase angle of the power signal. The systems may also include a power measurement unit configured to generate a second measurement based on the power signal, the second measurement characterizing an amplitude of one or more aspects of the power signal. The systems may further include a processing unit configured to identify a computational operation implemented by a target processing device, the identifying of the computational operation being based on a comparison of the first measurement and the second measurement with reference measurements.
