Abstract :
Using optical processing techniques, we experimentally enhance the physical layer security of optical communication systems. The multilevel security provided improves the confidentiality and availability of the network. We also introduce the use of optical CDMA as backup channels to achieve a bandwidth-effective way to counter physical infrastructure attacks.
