Abstract: A method for detecting physical attacks on a computing device includes embedding a sensor or FPGA (Field Programmable Gate Array) on a circuit board for gathering a frequency response of a power distribution network providing power to the circuit board. During operation of the circuit board, the sensor identifies and gathers a frequency response suspected of resulting from a tamper effort, and compares the identified frequency response to a frequency response of tempering events. Based on the comparison, a determination of tampering is made.
