SPAD PUFs: Reconfigurable Physically Unclonable Functions Using Single-Photon Avalanche Diodes

We present a study on physically unclonable functions (PUFs) derived from the dark signal non-uniformity (DSNU) of a perimeter-gated single-photon avalanche diode (pg-SPAD) CMOS imager. We introduce a method for generating unique and chip-specific signatures by leveraging challenge-response pairs (CRPs) with pixel addresses serving ...
