An optical communications network incorporating photonic layer security, with secure key exchange without loss of data, and a method of operating the network are disclosed. The network comprises a transmit side and a receive side. The transmit side includes first and second scramblers and a transmit side switch; and the receive side includes first and second descramblers and a receive side switch. The scramblers use encryption keys to encrypt optical signals, and the descramblers use the encryption keys to decrypt the encrypted optical signals. The encryption keys can be updated randomly and at will by installing new encryption keys on the scramblers and descramblers, and the transmit side and receive side switches are synchronized so that all of the optical signals that are encrypted using a new or updated encryption key are decrypted using the same new or updated encryption key. |
