Recent bibliographic sampling of Simon Robert Wiseman patents listed/published in the public domain by the USPTO (USPTO Patent Application #,Title):



05/28/15 - 20150150112 - Apparatus and method for connecting computer networks
Apparatus (104) for connecting two or more computer networks having two or more network interface machines (201, 202, 203) each arranged to be connected to a respective computer network with a bidirectional communications link (105, 106, 107) enabling the network interface machine to receive data from and transmit data to...
Inventors: Simon Robert Wiseman (Deep-secure Limited)

09/06/12 - 20120226917 - Data content checking
A data content checker arrangement for protecting communication between a sensitive computer system (102) and an external computer system (104). The arrangement includes a store (108) connected to input and output sub-systems (106) and (114) and to content checkers (110) and (112) arranged in parallel. The input and output sub-systems...
Inventors: Simon Robert Wiseman, Katherine Jane Hughes (Qinetiq Limited)

09/06/12 - 20120226914 - Checking data content
A system for automated checking of data content includes content checkers (208) to (214) arranged in parallel and connected between an input sub-system (204) and an output sub-system (216). The content checkers (208) to (214) check different data formats. Incoming data from an external computer system (202) is passed by...
Inventors: Simon Robert Wiseman, Katherine Jane Hughes (Qinetiq Limited)

07/12/12 - 20120177201 - Methods and apparatus for use in quantum key distribution
Methods and apparatus for use in quantum key distribution (QKD) are described. A quantum QKD signal is generated at a source and transmitted through a fibre optic network to an endpoint, a key being agreed with communication over a classical QKD channel. The classical QKD channel contains additional information relevant...
Inventors: Stephen Gerard Ayling, Simon Robert Wiseman, Brian Sinclair Lowans (Qinetiq Limited)

09/22/11 - 20110231665 - Method of performing authentication between network nodes
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...
Inventors: Simon Robert Wiseman (Qinetiq Limited)

09/22/11 - 20110228937 - Method of establishing a quantum key for use between network nodes
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...
Inventors: Simon Robert Wiseman, Richard Middleton Hicks, Brian Sinclair Lowans (Qinetiq Limited)

09/01/11 - 20110213979 - Quantum key distribution
The invention relates to methods and apparatus for Quantum key distribution. Such methods including authenticating a first node in a communications network with a remote node in the communications network. The authentication may include connecting an authentication device to the first node, agreeing a quantum key between the first node...
Inventors: Simon Robert Wiseman, Brian Sinclair Lowans, Stephen Gerard Ayling (Qinetiq Limited)

03/24/11 - 20110069972 - Multiplexed quantum key distribution
The present invention relates to an improved quantum signal transmitter, which has a plurality of quantum output channels having at least one optical source and at least one optical splitter acting on the output of said at least one source. Such a transmitter can easily be used with existing passive...
Inventors: Simon Robert Wiseman, Brian Sinclair Lowans, Stephen Gerard Ayling, Ewan David Finlayson (Qinetiq Limited)

12/30/10 - 20100329459 - Multi-community network with quantum key distribution
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...
Inventors: Simon Robert Wiseman, Brian Sinclair Lowans, Richard Andrew Oak (Qinetiq Limited)

11/25/10 - 20100299526 - Network having quantum key distribution
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...
Inventors: Simon Robert Wiseman, Brian Sinclair Lowans (Qinetiq Limited)

11/18/10 - 20100293380 - Quantum cryptography apparatus
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...
