Abstract
One feature pertains to a near field communication (NFC) target device comprising a memory circuit adapted to store sensitive data, an NFC interface adapted to transmit and receive information using NFC protocols, and a processing circuit. The processing circuit receives a plurality of provider identification (PID) numbers from a plurality of providers, where each PID number is associated with a different provider. The processing circuit also stores the PID numbers at the memory circuit, and assigns a privilege mask to each PID number received and stored. The NFC target device may also include a physical unclonable function (PUF) circuit. The processing circuit may additionally provide one or more PID numbers as input challenges to the PUF circuit, and receive one or more PUF output responses from the PUF circuit, where the PUF output responses are different from one another and are associated with different providers.
