A Framework for the Evaluation of Physical Unclonable Functions

A PUF is a chip-unique challenge-response mechanism exploiting manufacturing process variation inside integrated circuits (ICs). It has many useful applications such as device authentication and secure, memory-less key storage. A mobile device can be authenticated using a PUF challenge-response pair. Moreover, a cryptographic key can be securely embedded in a mobile device using a PUF without an expensive storage circuit such as flash memory therefore reducing resource cost and solving key storage issues.
