Abstract
Systems and methods are disclosed herein for implementing a secure hardware component by dividing a single Physically Unclonable Function (PUF) into several PUF challenge space subsets and mapping each subset to each requesting entity. In one example of the secure hardware component, the controller divides a challenge space of the PUF into multiple challenge space subsets and performs a mapping of allowed requesting entities to the plurality of challenge space subsets, respectively. The secure hardware component receives a request for an output from the requesting entity, which comprises a set of parameters. The controller determines whether the request is a valid request based on the set of parameters and forwards the challenge to the response generation subsystem. The response generation subsystem generates the output based on the challenge and forwards it to the requesting entity.
