Abstract

Reconfigurable Physical Unclonable Function In article number 2504288, Dong Ki Yoon, Moon Jong Han, Hee Seong Yun, and their colleagues develop reconfigurable physical unclonable function (PUF) integrating optical and electrical responses by using unique optical fingerprint textures and random molecular alignment of the semiconductive smectic liquid crystal. This approach enhances security by enabling hierarchical authentication, providing robust solutions for anticounterfeiting and cryptographic applications.
