Spectral physical unclonable functions: downscaling randomness with multi-resonant hybrid particles
Abstract Optical physical unclonable functions (PUFs) are state-of-the-art in advanced security applications. Fabricated with inherent randomness, they generate fingerprint-like responses, serving as trust anchors for material assets. However, the existing PUFs, typically reliant on microscopic spat...
