Physical Unclonable Functions (PUFs) have demonstrated great potential as fast and robust hardware security primitives. Public physical Unclonable Functions (PPUFs) have removed the main conceptual limitations of PUFs by enabling the creation of public key protocols. Traditional methods of constructing PPUFs leverage intrinsic process variation in submicron integrated circuits. However, these implementations impose high power usage and require long simulation times, producing high latency protocols. The authors propose to use next generation CMOS-compatible technologies, such as memristors and nanowires, whose components exhibit non-linear circuit characteristics, for the creation of PPUFs.
