Quantum Cryptography For Secure Optical Networks
Dense Wavelength Division Multiplexing optical networks transport a huge aggregate traffic exceeding Tbps per single fiber, and passive optical network technology has been extended to include the residential and enterprise network layer with Fiber-to-the Premises. Because this network allows for multimedia and extremely high data rates to end-users, optical communications security is important not only on the client and the node management layers, but also on the physical layer. Thus, cyber-security becomes also important in optical networks, including unbreakable cipher keys, cipher key distribution, identification of malicious actors, source authentication, physical link signature, and countermeasure strategies. In this paper we overview the security of the WDM optical network. We discuss advanced cryptographic methods that stem from quantum mechanics, known as quantum cryptography, and we identify specific vulnerabilities. We also look into the security of the next-generation optica...
