Abstract:
An apparatus and method for detecting a change in electrical properties in a system is disclosed. Embodiments of the disclosure enable the detection of a change in electrical properties in a system by, in response to a load generated on a power delivery network power in at least part of the system, measuring noise induced in the power delivery network in response to the load. Based on the measured noise, a dynamic-response property of the power delivery network is determined and the dynamic-response property is compared to a stored reference dynamic-response property of the power delivery network based on a predetermined load. In the event of a difference between the dynamic-response property and the reference dynamic-response property, a response to the event is triggered to indicate tampering with the power delivery network.
