Time-domain wavefront shaping for secure communication — •Matthias C. Velsink and Pepijn W.H. Pinkse — MESA+ Institute for Nanotechnology, University of Twente, Enschede, The Netherlands

Recently, we applied wavefront shaping techniques to implement quantum-secure readout of a physical unclonable key for authentication [1] and communication [2]. Unfortunately, spatial wavefront shaping is unsuitable for long-distance use. We therefore propose to use wavefront shaping in the time domain using a single spatial mode. We show spatiotemporal control of a pulse through a complex medium. Furthermore, we investigate a secure communication method based on physical unclonable functions in the time domain. We will report on the progress.
