Abstract
In this work, we study the sensitivity of Fano-type resonant scattering from a core-shell (plasmonic-dielectric) nanoparticle and its potential applications in optical encryption and hardware security. Specifically, we present the physical unclonable function (PUF) based on the scattering cross section (SCS) spectra of core-shell nanoparticles, of which the ultrahigh sensitivity near the Fano resonance makes their scattering properties highly sensitive to nanomanfacturing process variations. Such a property leads to a perfect entropy source for the generation of PUF-based cryptographic keys encoded in scattering responses. Our numerical and statistical results show that this optical PUF can exhibit excellent uniqueness and randomness for effective encryption.
