Reproducibility of deterministic multiple scattering media via direct laser writing

Activity: Talk or presentationOral presentation


Optical multiple scattering media have all the characteristics of a physical unclonable function (PUF). On this account, there is a number of authentication systems relying on such media [1,2,3]. The unclonability assumption depends on technological constraints. We attempt to falsify this assumption by creating deterministic scattering medium via direct laser writing (DLW) [4]. We predict that DLW can create and reproduce a small multiple scattering medium.
