Patent number: 9692595Abstract: Methods and apparatus for quantum key distribution are described, in particular including methods and networks 300 arranged to improve and/or ensure the security of data transmitted thereby by (i) ensuring a certain level of loss within at least part of the network, (ii) placing a penultimate and an endpoint nodes in situated in a secure second enclave, (iii) analyzing a transmitted bit stream to ensure that it does not provide an unacceptable amount of information about the key that may be generated therefrom, and/or (iv) varying the order in which bits are used to generate a key.Type: GrantFiled: December 1, 2011Date of Patent: June 27, 2017Assignee: QINETIQ LIMITEDInventors: Brian Sinclair Lowans, Richard Middleton Hicks

Patent number: 8855316Abstract: 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.Type: GrantFiled: January 23, 2009Date of Patent: October 7, 2014Assignee: Qinetiq LimitedInventors: Simon Robert Wiseman, Brian Sinclair Lowans, Richard Middleton Hicks

Patent number: 8681982Abstract: 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.Type: GrantFiled: December 2, 2009Date of Patent: March 25, 2014Assignee: Qinetiq LimitedInventors: Simon Robert Wiseman, Richard Middleton Hicks, Brian Sinclair Lowans

Patent number: 8654979Abstract: The present invention relates to an improved quantum key device for use in quantum key distribution, which device comprises a quantum detector unit for detecting a quantum signal and a plurality of logic units operably connected to the quantum detector unit wherein each logic unit is arranged to derive a separate quantum key from the quantum signal detected. In this way, a single quantum key distribution (QKD) receiver can generate separate quantum keys for separate users.Type: GrantFiled: May 15, 2009Date of Patent: February 18, 2014Assignee: Qinetiq LimitedInventor: Richard Middleton Hicks

Patent number: 8151117Abstract: Detection of items stored in a computer system such as computer code, data or information includes obtaining signatures characteristic of programs of interest such as steganographic programs. A signature is obtained by reading code from a program of interest. The code may consist of the first 500 bytes from a .DLL file taken from the programs' core steganographic kernel. This code is then the signature. The computer system compares the signature with files it holds, other than files on a prearranged exclusion list. If a signature is found to match data in a file, the filename, the finding of steganography in it, the file location and the matched signature are recorded by the computer system for output to its user.Type: GrantFiled: October 25, 2004Date of Patent: April 3, 2012Assignee: VocalComm Group, LLCInventor: Richard Middleton Hicks

Patent number: 6574730Abstract: An authentication system of a terminal on a public switched telephone network provides a security node associated with a local exchange and a network terminal. For one-way authentication, the terminal responds to a call initiation by sending a unique authentication code comprising a number and a secret key encrypted according to a first algorithm, the secret key being specific to the terminal. The security node constructs the expected authentication code from the number, using the first algorithm and a second key which is a function of a terminal identification number, and compares the expected code with the received code. In two-way authentication, the security node responds to the call initiation by sending a transaction number to the terminal encrypted according to a second algorithm. The terminal generates the authentication code as a function of the first algorithm, the secret key and the transaction number. The authentication code is sent back to the security node.Type: GrantFiled: February 11, 1997Date of Patent: June 3, 2003Assignee: British Telecommunications plcInventors: Robert Andrew Bissell, Kevin Paul Bosworth, Michael John Britnell, Peter Maxwell Harding, Richard Middleton Hicks, Jonathan James Kingan, Michael Victor Meyerstein, Keith Eric Nolde, John Rabson, Jonathan Crispin Ranger, David Anthony Roberts, Mark Jonathan Stirland, Richard Paul Swale
