After Quantum Keys are Distributed: Physical-Layer Encryption Aided by Optical Noise

Abstract

AlphaEta is a practical physical encryption system: " Performance similar to standard systems: ~1dB performance reduction " Uses off the shelf components " Use best available traditional cryptographic algorithms " Improved security via random noise / added complexity " Known plain text attack low correlation statistical attack " Lots of practical issues for Eve- How to phase-lock to a dense, noisy Mary " Demonstrated Drop-in compatibility with all-optical fiber networks- 850km " 2.5Gb/s data rates attainable now
