Abstract
A system for authenticating a circuit includes: a processor; and a memory, and the memory has stored thereon instructions that, when executed by the processor, cause the processor to: periodically measure physical characteristic data of the circuit, operational data of the circuit, and environmental data; periodically capture the measured data; generate a dynamic fingerprint based on an aggregation of the captured data, and the dynamic fingerprint is a compound data structure encapsulating the aggregated data; associate metadata with the dynamic fingerprint; and output the dynamic fingerprint as a physically unclonable function (PUF) of the circuit.
