Physical Unclonable Functions for Device Authentication and Secret Key Generation
Physical Unclonable Functions (PUFs) are innovative circuit primitives that extract secrets from physical characteristics of integrated circuits (ICs) We present PUF designs that exploit inherent delay characteristics of wires and transistors that differ from chip to chip, and describe how PUFs can enable low cost authentication of individual ICs and generate volatile secret keys for cryptographic operations.
