Fabrication of Physically Unclonable Functions via Additive Manufacturing


As a new method of encryption with a wide field of applications, Virginia Tech has proposed a novel idea of creating unclonable parts embedded with nanomaterials through 3-D printing methods. Due to the semi-ordered and semi-random nature of the distributed nanomaterials, parts would be nearly impossible to recreate. The nanomaterials can be detected in different manners such as radio-waves, fluorescence, or spectroscopy. The range of possible combinations of nanomaterials and designs of the 3-D printed part allows for a nearly infinite set of physical unclonable functions.
