Method and apparatus for detection of counterfeit parts, compromised or tampered components or devices, tampered systems such as local communication networks, and for secure identification of components

Abstract

Methods, systems and techniques are provided to authenticate a device under test (DUT)/system under test (SUT) comprising an electronic component(s). A profile is defined by injecting a signal to elicit an output that is responsive a physical characteristic of the type of DUT/SUT. In respective embodiments the injected signal is defined to elicit an output for time-domain or frequency-domain evaluation. An injected signal may comprise combinations of (non-destructive/non-activating) signals applied to multiple access points for measurement at arbitrary access points of the DUT/SUT. In an embodiment, measurements of multiple DUT/SUTs of a same type are used to define a common profile. In an embodiment, the profile is built using machine learning to define a classifier. In other embodiments, statistical profiles are defined. During use, output is generated for a target DUT/SUT for evaluation relative to the profile. Counterfeit/alternate designs, altered designs, and implants are detectable.
