摘　　要：The increased prevalence of the Internet of Things(IoT)and the integration of digital technology into our daily lives have given rise to heightened security risks and the need for more robust security measures.In response to these challenges,physical unclonable functions(PUFs)have emerged as promising solution,offering a highly secure method to generate unpredictable and unique random digital values by leveraging inherent physical characteristics.However,traditional PUFs implementations often require complex hardware and circuitry,which can add to the cost and complexity of the system.We present a novel approach using a random wrinkles PUF(rw-PUF)based on an optically anisotropic,facile,simple,and cost-effective material.These wrinkles contain randomly oriented liquid crystal molecules,resulting in a two-dimensional retardation map corresponding to a complex birefringence pattern.Additionally,our proposed technique allows for customization based on specific requirements using a spatial light modulator,enabling fast fabrication.The random wrinkles PUF has the capability to store multiple data sets within a single PUF without the need for physical alterations.Furthermore,we introduce a concept called‘polyhedron authentication,’which utilizes three-dimensional information storage in a voxelated random wrinkles PUF.This approach demonstrates the feasibility of implementing high-level security technology by leveraging the unique properties of the rw-PUF.
