Project Type MQP Submission date 2009-04-30 Author Matthew Daniel Dailey, MA URN E-project-043009-165443 Title Authentication Schemes based on Physically Unclonable Functions Advisor Martin, William J, MA Availability unrestricted Abstract
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.
