The project investigates the problem of communication security in the mobile environment where both confidentiality and authenticity are of prime concern. Stream ciphers are a very natural choice in mobile environment as they provide an efficient cryptographic protection using a limited computing resources. We model stream cipher as a system of multivariate equations. In this approach, security of stream ciphers can be measured as the complexity of an algorithm that solves the appropriate system of equations. This project leads to new techniques for the design and analysis of stream ciphers.Read moreRead less

Wireless sensor and communication networks with fixed and mobile nodes are rapidly becoming essential technologies for hostile environmental monitoring, battlefield surveillance and precision agriculture. However, due to the complexities associated with interconnected design issues involving sensors, autonomous vehicles and communication protocols, even very simple networks have proven to be difficult to design. This project proposes to intelligently employ higher capabilities of mobile nodes and develop methods for rapid deployment, maintenance and routing that are aware of location, energy, and security. The outcomes of this project will form the basis for design of intelligent wireless networks for defence and civilian applications.Read moreRead less
Architecture-based Open Network Management Systems for Next Generation Telecommunications. We aim to develop an open, policy-based architecture for the management of next generation telecommunications networks. It is expected that a comprehensive Open Architecture-based Telecommunications Management Network (AuTuMN) framework could be put in place to manage the network based on centralised policies and roles rather than having to handle individual users and elements. Significantly, the scient ....Architecture-based Open Network Management Systems for Next Generation Telecommunications.

Efficient interconnection of photonic components is the most critical research problem facing the photonics industry in its efforts for integration. In this project, interconnects for photonic systems will be developed, utilising a recently developed new class of fibres - microstructured optical fibres, which have been called 'the next generation' of optical fibres because of their ability to produce a variety of tailorisable optical effects. Specially designed and modified microstructured fibres will be developed to achieve efficient coupling from fibre to planar waveguide circuits, and to a range of photonic band gap devices that are currently being developed by the industry partner.Read moreRead less
Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessib ....Captions for the Deaf and Hearing Impaired: Availability versus Accessibility. The availability of educational, informational and recreational services for deaf and hearing-impaired people has been dramatically facilitated by (i) increased television captioning due to the 2001 introduction of the Television Broadcasting Services Act; and (ii) trial introduction of real-time captioning in educational settings. These innovations must be matched by equally innovative ways of increasing the accessibility of captions, which is currently limited by English literacy, caption speed, and caption reduction techniques. Here, systematic manipulation of these factors in experiments on television captioning with adults and educational captioning with children will determine how resources might best be directed to improving caption accessibility.Read moreRead less
