Abstract

Passive Optical Networks (PON) are widely used to deliver fixed line communication due to their cost effectiveness and potential for high data transfer rates. However, due to the nature of their operation, every user on a PON system has access to every other user’s downstream data. Current progress in quantum computing means that the classical encryption algorithms currently used to secure communication data, including PON data, may not be sufficient in the future and so, for total information security another encryption solution, such as Quantum Key Distribution, must be found. This paper outlines the different variations of QKD on PON that have so far been proposed and summarises the current state of the art of experimental demonstrations of QKD on PON.
