Abstract

Disclosed is a method for a location-based secure communication based on IRS. The controlled multipath components of the reflected signal are exploited by IRS, and secure communication is enabled through shuffling the phases of those components so they add constructively only at the intended receiver.

Claims (4)

1 . A method for location-based secure communication based on intelligent reflecting surface (IRS) by encoding reflected multipath components, the method comprising:

setting a tier-1 beamforming to focus a reflected signal toward a receiver;

setting a tier-2 beamforming to change during transmission; and

selecting phase of the reflected multipath components SO that a resolved multipath component at the receiver has a strength above a given accepted power threshold, the resolved multipath component being a linear combination of physical components corresponding to segments thereof, wherein the step of setting the tier-2 beamforming is achieved by grouping the segments in pairs such that one segment of the segment of pairs selects a random phase and another segment of the segments in pair selects one to remove an effect thereof and a user location for a given pair for one phase duration, wherein another pair is selected randomly in a following phase duration.
