  • Patent number: 8885828
    Abstract: This invention relates to an optical star network in which different communities of users, such as different businesses, are provided through use of quantum key distribution (QKD). At least one QKD device is located at the central hub of the star network and communicates with QKD devices at the endpoints to establish a separate quantum key, i.e. a cryptographic key established by QKD, with each endpoint. A separate key manager is provided for each different community and each key manager is arranged to use the appropriate quantum keys for endpoints within that community to deliver the same community key to each endpoint. This community key can be used by for encrypting network traffic between members of the same community with security. Traffic passing through the network switch is encrypted, but the community keys are not delivered via the switch and hence the switch an error in the switch does not compromise security.

  • Patent number: 8855316
    Abstract: The method involves exchange of a quantum signal between a first quantum node and a second quantum node as is usual in known quantum key distribution (QKD) scheme. The first quantum node communicates details of the quantum signal it sent or received with a first remote node. The first remote node thus has all the information to required to take the place of the first quantum node in the key agreement step with the second quantum node. The first quantum node may be arranged to transmit the quantum signal to the second quantum node, in which case the invention provides a distributed quantum transmitter with the control logic in the first remote node being distributed remotely from the actual quantum transmitter in the first quantum node. Communications between the first remote node and first quantum node may comprise or be protected by a quantum key derived by conventional QKD.

  • Patent number: 8842042
    Abstract: A method of compensating for or correcting satellite ephemeris error involves measuring time difference of arrival (TDOA) and frequency difference of arrival (FDOA) for signal replicas received via two satellites (34, 46) from calibration transmitters (42a to 42d) at different geographical locations. An initial satellite ephemeris consisting of position and velocity vectors is used to calculate ephemeris changes yielding estimated TDOA and FDOA values providing a best fit to measured TDOA and FDOA values. This provides estimated changes required to compensate for or to correct errors in the initial satellite ephemeris. The method may be iterated to deal with large ephemeris changes: i.e. the changes obtained in one iteration may be used to correct ephemeris for use as a new initial ephemeris in a following iteration. The method may be used to correct ephemeris errors in one or both satellites, if so a greater number of calibration transmitters EphemCal 1 to EphemCal 10 may be used.

  • Patent number: 8762728
    Abstract: A method of authentication between first (QNodeX) and second (QNodeY) network nodes within a network suitable for implementing quantum cryptography comprises steps in which the first and second nodes each generate a cryptographic hash ([MXY]AI, [MYX]AJ) of a message ([MXY], [MYX]) using respective authentication keys (AI, AJ) shared with a third network node (QNodeW). The messages may be those exchanged between the first and second nodes during agreement of a quantum key to be used between the nodes. An authentication key to be shared by the first and second nodes may be established using the quantum key. The invention therefore allows an authentication key to be established and shared between the first and second network nodes without direct physical intervention. Networks having large numbers of network nodes may be re-keyed following replacement or maintenance of a network node much more quickly and easily than is the case where re-keying is achieved by physically supplying shared authentication keys.

  • Patent number: 8681982
    Abstract: A method of establishing a quantum key for use between a first network node (QNode1) and a second network node (QNode3) in a network for carrying out quantum cryptography includes a key agreement step carried out by a third node (QNode2) and the second node (QNode3) and a subsequent authentication step carried out by the first and second nodes directly. As the key agreement step does not involve QNode1, another key agreement step may be simultaneously performed by another pair of network nodes QNode4, QNode5 to agree a quantum key for use by network nodes QNode1 and QNode5. The invention allows respective quantum keys to be established between a network node and each of a set of other nodes more rapidly than is the case if each quantum key is established serially by key agreement and authentication steps.

  • Publication number: 20140074944
    Abstract: Methods and computer program products for establishing communication events between an initiator user and a recipient user over a first communication system. The initiator and recipient users are contacts within a second communication system but are not contacts within the first communication system. For the initiator and recipient users, an association between a first user identity in the first communication system and a second user identity in the second communication system is determined. The initiator user device uses the association for the recipient user to determine the first user identity of the recipient user. A setup request to establish the communication event is sent over the first communication system from a first initiator client to a first recipient client. A communication event is authorized to proceed over the first communication system on the basis that the initiator user and the recipient user are contacts within the second communication system.

  • Patent number: 8650401
    Abstract: A method of performing quantum key distribution across a network. The method involves a first node first agreeing a quantum key with a first intermediate node in the path. Next the intermediate node exchanges a quantum signal with the next node in the path—which is a targeted node. The intermediate node communicates with the first node using the previous established quantum key details of the quantum signal sent or received by the intermediate node. The first node then performs a key agreement step to agree a quantum key directly with the targeted node. Having established a quantum key with the current targeted node the method can be repeated but with the next node in the network path as the targeted node until a destination node is reached. The final quantum key agreed with the destination node can then be used for encrypting communication between those nodes across the network.

  • Publication number: 20140037408
    Abstract: The invention is directed to a material loader for quickly and easily loading material, particularly bulk material, into a containment apparatus. Material to be loaded is placed inside a bin that is dimensioned to fit inside the containment apparatus. In use the containment apparatus is positioned so that the bin is inside the containment apparatus and the containment apparatus or a vehicle bearing the containment apparatus is connected to a material transfer member inside the bin. Forward movement of the containment apparatus/vehicle causes the material transfer member to hold against the material while the bin slides out of the containment apparatus from the point of view of the containment apparatus, leaving the material behind. In other words, the forward movement of the containment apparatus/vehicle causes the material transfer member to pull the material into the containment apparatus. The invention may also be used for unloading a containment apparatus.
