PUF Emulation Key (PEK)

The PUF emulation key (PEK) is a 256-bit factory-defined key unique to each device that is randomly generated by the device during initialization of the factory keys. This key is used only in the PUF emulation protocol.

Note: The PEK is not generated by the PUF circuit every time the user recalls it, but is instead a static programmed value that is read from Flash bits.
