In this project we investigate dierent hardware authentication schemes based on Physically Unclonable Functions. We start by analyzing the concepts of a fuzzy extractor and a secure sketch from an information-theoretic perspective. We then present a hardware implementation of a fuzzy extractor which uses the code oset construction with BCH codes. Finally, we propose a new cryptographic protocol for PUF authentication based upon polynomial interpolation using Sudan's list-decoding algorithm. We provide preliminary results into the feasibility of this protocol, by looking at the practicality of nding a polynomial that can be assigned as a cryptographic key to each device.
