Physical Unclonable Functions (PUFs) are employed to generate unique signature to be used for Integrated Circuit (IC) identification and authentication. Existing PUFs exploit only process variations for generating unique signature. Due to the spatial correlation between process parameters, such PUFs will be vulnerable to be modeled or leak information under side-channel attacks. The PUF, the authors present in this paper, called PE-PUF, takes into account both process and environmental variations which magnifies chip-to-chip signature randomness and uniqueness.
