Study on PUF based secure protection for IC design

The rapid progress in integrated circuit (IC) technology makes the gates in a single chip increase by Moore's law. The complexity in design and verification grows accordingly. To address this issue, intellectual property (IP) reuse is prevalently used in system design. However, it may incur IP piracy or illegal copy, which brings big threat to IP protection. When IP dispute occurs, the ownership verifier can activate the Challenge Response Pair (CRP) of Physical Unclonable Function (PUF) to verify IP copyright. In this work, we have analyzed and summarized PUF techniques and current research status. Furthermore, several typical PUF techniques are concretely illustrated and compared. Besides, we demonstrate PUF in multiprocessor by analyzing security and overhead on previous PUF techniques. Finally, we envision the future of PUF techniques and their applications.
