Ultradurable Embedded Physically Unclonable Functions. [PDF]
ACS Appl Mater InterfacesPhysically unclonable functions (PUFs) have attracted growing interest for anticounterfeiting and authentication applications. The practical applications require durable PUFs made of robust materials. This study reports a practical strategy to generate extremely robust PUFs by embedding random features onto a substrate.
