Concealable Physically Unclonable Functions via Wetting-Driven Tunable Opacity in Smart Nanofibrous Mats.
The concealing of uniquely identifiable information is pertinent to both anti-counterfeiting and information security technologies. Current optical physically unclonable functions (PUFs) are based on static stochastic features that make them inherently vulnerable to undesired tampering. This study proposes wetting indu...
