Quantum-Safe Physical Layer Security in Optical Networks

Abstract
Selected approaches to securing the physical layer of optical communication systems are discussed, taking into account different intervention scenarios into the physical channel as well as adversary’s capability to replace conventional detection of the intercepted signal by more general measurement strategies permitted by the laws of quantum physics. Examples include wiretap coding, quantum key distribution, and optical key distribution. It is found that legitimate parties can ensure protocol security over a broad range of system parameters even with restricted technical resources compared to those available to an adversary.
