  • Optical encryption terminal, cryptography key distribution system and method of generating cryptography keys in a cryptography key distribution system
    Patent number: 12063298
    Abstract: An optical encryption terminal for generating and distributing a cryptographic key signal in a cryptography key distribution system having at least two optical encryption terminals. The optical encryption terminal comprises an electronic processing unit and the optical encryption terminal is configured to selectively receive optical input signals generated by a source of electromagnetic radiation and optical input signals generated by a further optical encryption terminal, and to selectively output first optical output signals to a detection element and second optical output signals to the further optical encryption terminal, wherein the first optical output signals are based on the optical input signals generated by the further optical encryption terminal and transformed in accordance with an optical encryption pattern provided at the optical encryption terminal.
