Overview

This file illustrates how to do PUF registration and generating syndrome data and obtaining helper data, debug 2 result, Auxiliary and CHash values from generated syndrome data.

This example also encrypts the provided AES key with PUF and generates the black key. Finally programs the PUF code and black key into eFUSE on user request (provided in xilskey_puf_registration.h)
