In today’s globalized economy, it has become standard business practice to include third party Intellectual Property (IP) into products. However, licensing IP to third parties forces IP vendors to ensure that they can generate revenue from their internally developed IP blocks. This is only guaranteed if designs are properly protected against theft, cloning, and grey market overproduction. In this paper, we describe a solution for the IP protection problem on Field Programmable Gate Arrays (FPGAs) based on the use of Physical Unclonable Functions (PUFs). Our solution includes optimizations at the protocol level, making the resulting protocols more efficient than previously proposed ones. In addition, we show how SRAM memory blocks present in current FPGAs can be used as a PUF. This leads to a solution which allows unique identification of FPGAs without requiring significant additional hardware resources, and to ensure code can only run on authorized platforms.
