TECHNICAL FIELD

This disclosure relates in general to the field of semiconductors and, more particularly, to device asymmetric attestation using a physically unclonable function (PUF).

BACKGROUND

Client platforms, such as personal computers (PCs) and game consoles, typically include any number of electronic components. For example, a client platform can include several compute only devices and application processors. The compute only devices include, but are not limited to, embedded controllers (ECs), on-board graphic processing units (GPUs), on-board voltage regulators (VRs), camera controllers, trusted platform modules (TPMs), and the like. These electronic components can be replaced with counterfeits and/or malicious devices, thereby compromising the security of the entire system. Components of the client platform are authenticated to determine if counterfeit and malicious devices are installed on within the client platform.
