Abstract
Recently, we applied wavefront shaping techniques to implement quantum-secure
readout of a physical unclonable key for authentication [1]. Unfortunately, spatial wavefront shaping is unsuitable for long distance use. We therefore propose to use
wavefront shaping in the time domain. We show temporal focusing 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.
