A Physical Unclonable Function (PUF) represents a sophisticated hardware security approach that harnesses the intrinsic variations within the semiconductor manufacturing process. This results in the creation of a distinct "digital fingerprint" for each individual chip, serving as a unique identifier. Typically, this technology is employed in semiconductor devices like microprocessors, offering physically defined output responses for critical security functions, including chip authentication and key generation.
