A flexible design flow for software IP binding in commodity FPGA

— Software intellectual property (SWIP) is a critical component of increasingly complex FPGA based system on chip (SOC) designs. As a result, developers want to ensure that their SWIP sources are protected from being exposed to an unauthorized party and are restricted to run only on a trusted FPGA platform. This paper proposes a novel design flow for protecting SWIP by binding it to a specific FPGA platform. We accomplish this by leveraging the qualities of a Physical Unclonable Function (PUF) and a tight integration of hardware and software security features. A prototype implementation demonstrates our design flow to successfully protect a SWIP by encryption using a 128 bit FPGA-unique key extracted from a PUF.
