Abstract

Three-dimensional (3D) printing is implemented to introduce randomness into systems and devices that are being manufactured. 3D printed physically unclonable wireless systems (PUWS) provide flexibility in system package complexity, number of physically unclonable function (PUF) based security measures/types, and customization of the PUF parameters. Using flexibility and economics of 3D printing, PUWS can combine multiple PUF measures in a 3D package for cryptographic secret keys and introduce PUFs at the physical layer of the communication system. A 3D printed wireless system packaging concept is described herein where 3D printing parameters are randomized to 1) generate new physically unclonable functions (at the physical layer), 2) generate new physically unclonable functions within the system package (rather than at integrated circuit (IC) level), and 3) combine multiple physically unclonable functions (such as optical and electrical/VIA based ones) within single device structure.
