Flexible Anti-Counterfeiting Labels Based on Lens-Free Plasmonic Physical Unclonable Functions
We report a scheme of realizing flexible anti-counterfeiting labels leveraging plasmonic physical unclonable functions. The devices were made by template-assisted deposition of heterogenous plasmonic gold nanoparticles and transferring onto polydimethylsiloxane substrates. Taking advantage of lensless imaging, the generated cryptographic keys exhibit nice uniqueness and repeatability upon repeated stretching up to 30% tensile strain.
