Abstract:
Systems, methods, and devices of the various aspects enable detecting anomalous electromagnetic (EM) emissions from among a plurality of electronic devices. A device processor may receive EM emissions of a plurality of electronic devices, wherein the receiving device has no previous information about any of the plurality of electronic devices. The device processor may cross-correlate the EM emissions of the plurality of electronic devices over time. The device processor may identify a difference of the cross-correlated EM emissions from earlier cross-correlated EM emissions. The device processor may determine that the difference of the cross-correlated EM emissions from the earlier cross-correlated EM emissions indicates an anomaly in one or more of the plurality of electronic devices.
Abstract:
Systems, methods, and devices of the various aspects enable detecting a malfunction caused by radio frequency (RF) interference. A computing device processor may identify a location of the computing device based on a plurality of real-time data inputs received by the computing device. The processor may characterize an RF environment of the computing device based on the identified location and the plurality of real-time data inputs. The processor may determine at least one RF emissions threshold based on the characterization of the RF environment. The processor may compare the characterization of the RF environment to the at least one RF emissions threshold, and may perform an action in response to determining that the characterization of the RF environment exceeds the at least one RF emissions threshold.
