A photonic shield spreads and phase-encodes data so it can’t be recorded or decrypted later—even by quantum computers. No raw data exists, and traffic plus key exchange run in one secure channel up to 200 Gbps.

Photonic security sends 100 Gbps over 200 km while hiding the signal under optical noise. Keys update constantly, preventing capture or later decryption, and it coexists with seven standard DWDM channels in real conditions

An all-optical spread-spectrum system hides data under noise; only real-time decoding with the right phase key works. Offline recovery is impossible. We analyze three attack methods and show when the photonic system stays secure.

A stealth all-optical scheme spreads the signal across a comb and hides it under noise. Only real-time decoding with the correct phase mask recovers it; others get unrecoverable noise. Demonstrated: 20 Gbps error-free at −7.5 dB OSNR.
