Keyless Range–Angle Secure Wireless Links in the Near-Field of an Ultra-Large-Scale RIS

Physical-layer security (PLS) complements cryptography at the wireless edge, yet most existing systems confine secrecy to the angular domain: an eavesdropper on the legitimate direction—merely nearer or farther—still captures clean constellations. This poster presents NF-SecRIS, a prototype that attains range–angle (2D...
