Providing End-to-End Quality of Service to Internet Applications. Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains.

Current Internet only supports limited quality of service (QoS) within isolated domains. This project allows critical applications to be deployed over the global Internet. The project employs a programmable architecture for composing services and intelligent software elements for negotiating acceptable QoS responses for individual application flows over multiple administrative domains. The architecture employs DiffServ's aggregation property to make it scalable for the Internet core. Successful outcomes would open the floodgates, allowing the development and deployment of applications such as high quality videoconferences, live sport broadcasts, remote medical services, network games, real-time on-line educations, and multimedia distributions.

Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discove ....Fair Intelligent Quality of Service Control and Path Discovery Mechanisms for Internet Scalable Architectures. Until now the Internet only provides best effort service without guaranteeing the timeliness or actual delivery of data. Quality of Service (QoS) architectures have been proposed but not deployed due to a fundamental problem: either the architecture is not scalable or it does not guarantee end-to-end QoS. The project tackles the problem by introducing mechanisms for network path discovery in the network core. The solution allows an integration of both scalability and end-to-end QoS architectures. The outcomes allow network providers to provision network resources efficiently, to develop competitive Internet-based products; and the service providers to develop quality services such as high quality IP phone, multimedia distributions.

Long-haul optical transport networks are key communication infrastructure between metropolises. Our research aims to discover cost-effective network architecture and planning and operational strategies for optical transport networks, which is beneficial to the deployment and operation of Australian telecommunication networks. In addition, viewing the sparse connectivity of Australian backbone transport networks, the research on network survivability will provide effective strategies for Australian transport networks to survive any network failures due to natural disasters or terror attacks, thereby providing reliable network services to Australian.

Visual Solutions for Automated Translation Between Spoken and Signed Languages. We propose to build a robust visual speech recognition system that analyzes images of spoken language and achieves a recognition of the utterances with at least human expert recognition rates. This visual speech recognition system will then be integrated with our existing gesture recognition system to improve performance, just as humans combine visual and audio data for language understanding. The result will be a sy ....Visual Solutions for Automated Translation Between Spoken and Signed Languages. We propose to build a robust visual speech recognition system that analyzes images of spoken language and achieves a recognition of the utterances with at least human expert recognition rates. This visual speech recognition system will then be integrated with our existing gesture recognition system to improve performance, just as humans combine visual and audio data for language understanding. The result will be a system providing translation between English and the Australian sign language Auslan in a practical application domain. Significantly, our work will provide insights into the cognitive models of neural activity linking language and gesture.Read moreRead less
Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission ....Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission is important to avoid fraud and maintain privacy.
Satellite links introduce a long delay (latency) in the transmission path and existing secure internet protocols do not handle this well. This is because in many situations, it is a requirement that the secure connection be implemented not only independently of the
satellite service provider but also in a reliable and efficient way.
This project will develop new practical solutions so that secure and reliable end-to-end connections can be provided over the satellite links.

Stream ciphers are a natural choice in mobile environments as they provide an efficient cryptographic protection using a limited computing resources. We treat stream ciphers as algebraic objects whose properties fully determine their cryptographic strength. We first analyse existing stream ciphers showing their algebraic properties and later we derive a design methodology for provably secure stream ciphers. The project leads to new secure and efficient designs for stream ciphers that are the preferred cryptographic tools used in Australian industry.Read moreRead less
Algebraic Analysis of Cryptosystems. This project studies an (new) algebraic approach to cryptanalysis of modern block ciphers. The approach works for all cryptosystems that use either small S-boxes, or their algebraic structure can be described by a system of overdefined quadratic equations. The cryptosystems that are potentially breakable using this approach are Rijndael and Serpent - the two top finalists of the Advanced Encryption Standard contest. The project also explores how this approach ....Algebraic Analysis of Cryptosystems. This project studies an (new) algebraic approach to cryptanalysis of modern block ciphers.

The cryptosystems that are potentially breakable using this approach are Rijndael and Serpent - the two top finalists of the Advanced Encryption Standard contest. The project also explores how this approach can be applied to design new and more powerful factoring algorithms. The project has an explosive potential to redefine the theory and practice of modern cryptography.Read moreRead less

Organisations are increasingly concerned with the effective utilisation of Web technologies, and especially the ways in which these technologies can be used to improve their business. Effective management of knowledge about the interplay between the organisation and technical drivers of this technology adoption will enable a much-enhanced process for leveraging emerging information and communication technologies. This project aims to link related research at UTS and Southampton University to understand how tools might support this knowledge management. Outcomes will include the creation of specific tools (and techniques for using them) within the context of managing organisational uptake of new technologies.Read moreRead less
