Abstract: A method for a PUK authenticated communication includes creating an optical challenge in a time-frequency domain, providing the optical challenge to a tPUK which includes a spatial input channel and a plurality of spatial output channels, and detecting in which of the plurality of spatial output channels a short temporally focused pulse is created. The tPUK provides a complex challenge-response behavior in the time-frequency domain. The optical challenge is created so that the tPUK creates the response having a short temporally focused pulse in only one of the plurality of spatial output channels of the tPUK.
