Abstract: A beacon device transmits a challenge message to each of one or more responder devices over a respective direct communication link, inviting each responder device to prove the existence of its respective direct communication link by transmitting to a respective recipient device, distinct from the beacon device, a respective response message indicating knowledge of contents of the challenge message. A predetermined time period after its transmission of the challenge message, the beacon device transmits a confirmation message indicating knowledge of the contents of the challenge message to a message store. A validation device then compares contents of each response message which preceded the confirmation message in time, if any, to contents of the confirmation message and infers therefrom which of the respective responder devices, if any, received the challenge message over the respective direct communication link.

Abstract: A beacon device including directional transmission means transmits a challenge message in a first predetermined direction to each of one or more responder devices over a respective direct radio communication link, to invite the responder devices to each transmit a respective response message indicating knowledge of contents of the challenge message. The beacon device transmits one or more directed repetitions of the challenge message in one or more respective further predetermined directions such that data relating to the location of each of the responder devices can be inferred from timings of each response message with respect to times the challenge message and the directed repetitions of the challenge message were transmitted. The beacon device either engages in or eschews subsequent two-way communication with each of the one or more responder devices over the respective direct radio communication link, in dependence on the existence and timing of a respective response message.

Abstract: A network device detecting possible malicious traffic and enlists the help of a co-operative group of downstream routers to perform enhanced deep packet analysis and firewalling in parallel with the transport of the packet through the network. The routers may also use other remote computational resource to perform some of the analysis along or close to the route 80 of the packet through the network. The packets are cached at the exit edge router, which does not release the packet from the cooperative group until all analyzers report the traffic is safe, or deletes the traffic if identified as malicious. By buffering at the remote end the packet can be forwarded promptly if approved, but protects downstream components if the traffic is malicious.

Abstract: An authentication method using a plurality of physical unclonable functions (PUFs). The plurality of PUFs includes a first PUF associated with a first device and a second PUF associated with a second device. A surface pattern of the first PUF corresponds to a surface pattern of the second PUF. The method includes obtaining a first response to a challenge using the first PUF, sending a request to the second device for a second response to the challenge obtained used the second PUF, receiving the second response, and determining whether the second device is authenticated based on a comparison between the first response and the second response.

The application also relates to a method of configuring an optical network.

Abstract: There is herein provided a method of quantum communication, the method comprising: indicating to a quantum receiving apparatus that a first sequence of mutually non-orthogonal bases will be used to prepare at least some of a plurality of bits in quantum states, at a quantum transmitting apparatus, preparing each of the plurality of bits in a respective one of a second sequence of mutually non-orthogonal bases, to give a plurality of qubits, wherein the second sequence of mutually non-orthogonal bases is different to the first sequence of mutually non-orthogonal bases.

Abstract: An agricultural admixture includes an acid, an organic amine, boron and one or more additional micronutrients, in which the boron and additional micronutrients are chelated, along with a saccharide. In the admixture, boron is present in an amount of at least 1.0 wt % thereof, the admixture contains a total boron and additional micronutrients content of at least 7.2 wt %, and the admixture remains stable, non-precipitated for at least 60 days. A method of spraying an agricultural admixture involves admixing the aforementioned admixture with one or more agricultural chemicals and spraying the admixture, where the admixture remains stable, non-precipitated for at least 60 days. A method of producing an agricultural admixture involves admixing the aforementioned admixture with one or more agricultural chemicals, where the admixture remains stable, non-precipitated for at least 60 days.

Abstract: Disclosed is apparatus and a method for detecting udder disease in dairy animals. An accelerometer is attached to each of a plurality of dairy animals. A processor determines a measure of the activity of the dairy animals to which the accelerometers are attached. Data is recorded by and automatically transmitted from a sensor unit secured to an animal, without the requirement for costly and time consuming chemical analysis of milk, or of visual or veterinary inspection of individual animals in a herd. The development of an udder disease in a dairy animal, such as mastitis, may be identified from a decrease in the monitored measure of activity of a dairy animal. A separate baseline measure of activity may be determined for each dairy animal and the activity of a plurality of dairy animals in one or more herds may be taken into account, in order to reduce false positives due to external effects which are not specific to a single dairy animal.
