Designing Physical Unclonable Functions From Optically Active Materials. [PDF]
Adv MaterAssigning unforgeable “fingerprints” to manufactured goods is a key strategy to fight global counterfeiting. Optical physical unclonable functions (PUFs) are chemically generated random patterns of optically active materials serving as unique authenticators.
