Description
Summary:Physical unclonable functions (PUFs) are next-generation anti-counterfeiting technologies that leverage random patterns generated during a manufacturing process to create inherently random and non-reproducible security keys. Optical PUFs, a type of PUF, utilize light interaction with nano-materials to create random patterns that serve as robust security keys. However, current optical PUFs using nano-materials are susceptible to production limitations, high costs, and limited encoding capacity. This paper presents MEMS-fabricated nano-structures as a promising alternative to nano-materials to address these limitations. Employing MEMS fabrication technology enables the cost-effective mass production of random nano-patterns across large areas while enhancing encoding capacity. The results of this study indicate that MEMS technologies can make significant contributions to PUF.
