On the (re)design of an FPGA-based PUF

Physically Unclonable Functions (PUFs) represent a promising basis for solutions to problems such as secure key storage, and delivery of higher-level applications such as authentication. Although effective PUF designs exist for CMOS-based technologies (e.g., arbiter PUFs), their implementation on FPGAs remains a challenge (e.g., because of their routing characteristics). With this in mind, Anderson described a PUF design specifically tailored towards FPGAs. In this paper we identify and analyse a flaw in said design which renders it impractical for security-critical use. We describe two alternative solutions (relating to different tradeoffs) that eliminate this flaw.
