Architecture for Reconfigurable Quantum Key Distribution Networks Based on Entangled Photons Directed by a Wavelength Selective Switch

摘要

A system and method for securing communications between a plurality of users communicating over an optical network. The system utilizes a fixed or tunable source optical generator to generate entangled photon pairs, distribute the photons and establish a key exchange between users. The distribution of entangled photon pairs is implemented via at least one wavelength selective switch.

1. A method comprising:
receiving a first plurality of photons during a scheduled duration period, each photon of the first plurality of photons comprising one photon of a pair of entangled photons; generating an encryption key based on the first plurality of photons; and encrypting a message using the encryption key to generate an encrypted message capable of decryption using a decryption key generated based on a second plurality of photons, each photon of the second plurality of photons comprising a respective other photon of the pair of entangled photons.
