Claim Text:
1. A method comprising: receiving a first plurality of photons beginning at a scheduled connection time and continuing for a scheduled duration, each photon of the first plurality of photons comprising one photon of a pair of entangled photons, each pair of entangled photons having a shared source frequency that is a middle band of a frequency band of a wavelength selective switch through which the first plurality of photons is transmitted; 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.
