Abstract
A device specific key is generated within an electronic device by providing a challenge to a physically unclonable function (PUF) structure integrated within the electronic device, where the PUF structure outputs a specific response based upon a specific challenge provided to the PUF structure. The PUF response is provided to a cryptographic module integrated within the electronic device, and a device specific key is generated by the cryptographic module utilizing a cryptographic key generation algorithm. The device specific key is generated based upon a combination of input data including the PUF response and data that is specific to the electronic device.
