Abstract: A multi-die device a first die containing a plurality of first die signal path elements configured to propagate a stimulus signal and a second die containing a plurality of second die signal path elements configured to propagate the stimulus signal. The multi-die device further includes an interposer configured to establish signal communication between the first die and the second die so as to deliver the stimulus signal from the plurality of first die signal path elements to the plurality of second die signal path elements to generate a propagation delay. The propagation delay is used to generate a single unified PUF response that is indicative of the authenticity of the multi-die device.

Abstract: Generally discussed herein are systems, devices, and methods for device verification. A method can include providing, by test equipment (TE), electrical stimulus consistent with a challenge of a challenge response pair (CRP) to a physical unclonable function (PUF) of a device under test (DUT), receiving, by the TE and from the DUT, a response to the electrical stimulus, comparing, by the TE, the provided response to responses to CRPs in a database including PUF CRPs associated with a device identification and a device type, and validating the identity of the DUT when the response of the PUF to the electrical stimulus matches the response of the CRP or invalidating the identity of the electrical device when the response of the PUF does not match the response of the CRP.

Abstract: Systems, devices, and methods for device or bio-organism authenticity verification are provided. A method can include identifying (i) respective challenges indicating respective stimuli and (ii) a root node hash value, generating the respective stimuli, recording respective responses to the respective electrical stimuli, hashing the respective responses resulting in respective hashed responses, hashing a combination of hashed responses of the respective hashed responses resulting in a key, and comparing the key to the root node hash value.
