Abstract: A computing device includes an optical network transceiver and a basic input/output system (BIOS). The optical network transceiver is to connect to an optical network and to generate an event indicating that an optical signal strength has attenuated below a threshold. The BIOS is to determine generation of the event by the optical network transceiver, and responsively detect occurrence of a potential optical network intrusion attack. In response to detecting occurrence of the potential optical network intrusion attack, the BIOS is to perform an action to protect the computing device from the potential optical network intrusion attack.

Abstract: The present invention improves data transmission safety and data transfer rate, and reduces an increase in costs when doing so. A map management unit 141 manages a map which defines a prescribed rule for dividing pseudorandom number data into two. On the basis of the rule defined by the map, a division unit 142 generates data obtained by dividing the pseudorandom number data into two as vertically irregular mapping input data and horizontally irregular mapping input data. A vertically irregular mapping unit 151 generates data obtained by subjecting the vertically irregular mapping input data to irregular mapping processing as vertical base reference point data. A horizontally irregular mapping unit 152 generates data obtained by subjecting the horizontally irregular mapping input data to irregular mapping processing as horizontal base reference point data. A base reference point information generation unit 133 decides on one base on the basis of the vertical base reference point data and the horizontal base reference point data.

Abstract: A reconfigurable QKD transceiver capable of transmitting and/or receiving qubits using a single optical hardware platform. This reconfigurable QKD transceiver enables various link scenarios specially for LEO-ground network, where the satellites have limited engagement time with a ground station. The reconfigurable QKD transceiver may reduce the optics SWaP by 50 percent and may allow for new mission scenarios that were otherwise not feasible with a transmitter only architecture or receiver only architecture.

Abstract: A data communication network includes a network node and a processor. The network node includes an optical link and a reflectometry analyzer. The reflection analyzer provides a plurality of reflectometry results that each provide a characterization of physical and operational properties of the optical link at the time of the reflectometry result. The processor receives a first set of the reflectometry results, analyzes the first set of reflectometry results to define a fingerprint of the physical and operational properties of the optical link, receives a second set of the reflectometry results, compares the second set of reflectometry results with the fingerprint, and determines whether or not the optical link is secure based upon the comparison of the second set of reflectometry results with the fingerprint.
