A physical unclonable function based on setup time violation

In this work, we propose a physical unclonable function (i.e. PUF) based on setup time violations. The paper presents the way the PUF has been developed detailing the successive design iterations. This work has been developed by Grenoble INP students (J. Dubeuf, M. Augagneur and Y. Clauzel) during the secure IC design course at Grenoble INP Esisar for the Embedded System Challenge during the Cyber Security Awareness Week (CSAW) 2011 organized by Polytechnic Institute of New York University.
