This project will also propose a novel integrated trust enhanced cloud security architecture, enabling the design of adaptive secure systems which will be more resilient to dynamic cyber security attacks. It will demonstrate the proposed models and architecture using a practical cloud based online application.Read moreRead less
Re-engineering internet timekeeping for scalability, accuracy and trust. This project aims to define and solve problems underpinning a secure and extensible system for network timekeeping, and implement and test a prototype under realistic conditions over the Internet. All computers incorporate a software clock, essential to software applications. A network is an inexpensive and convenient way to synchronise these clocks, but the Internet currently depends on an unreliable and insecure approach. ....Re-engineering internet timekeeping for scalability, accuracy and trust. This project aims to define and solve problems underpinning a secure and extensible system for network timekeeping, and implement and test a prototype under realistic conditions over the Internet. All computers incorporate a software clock, essential to software applications. A network is an inexpensive and convenient way to synchronise these clocks, but the Internet currently depends on an unreliable and insecure approach. The expected outcome will be trusted, accurate and reliable software clocks that support applications like cloud computing, billing systems and secure communications, which could become the timekeeping system for the Internet and the Internet of Things.Read moreRead less
Optical MIMO in Stokes Space: Bridging Coherent and Non-Coherent Detection. Coherent detection aided by high-speed electronic digital signal processors has transformed optical communications within the last decade. However, the high complexity of coherent detection has constrained its application to long-haul transmission. This project aims to propose a novel modulation format based on optical multiple-input multiple-output in Stokes space that can bridge the gap between coherent and non-coheren ....Optical MIMO in Stokes Space: Bridging Coherent and Non-Coherent Detection. Coherent detection aided by high-speed electronic digital signal processors has transformed optical communications within the last decade. However, the high complexity of coherent detection has constrained its application to long-haul transmission. This project aims to propose a novel modulation format based on optical multiple-input multiple-output in Stokes space that can bridge the gap between coherent and non-coherent communication. The proposed research includes design, simulation, and experimental verification of the proposed Stokes vector detection. The successful implementation of the project is expected to provide enabling technologies to future high-speed transport for interconnecting data centres that underpin fast-growing cloud computing.Read moreRead less

This project aims to develop the concept and demonstrate the practicality of a new fibre optic communication technology that allows data transmission rates beyond currently accepted fundamental limits. This project aims to design and demonstrate the feasibility and practicality of utilising nonlinear modes of data transmission. This would assist in the management of fibre impairments that fundamentally limit further increase in data rate causing the capacity crunch problem. This is expected to present Australia with leading edge technology to compete in the area of high-speed, high-capacity communication, which is the backbone of our economy, heath, education, social participation, and security.Read moreRead less
Extremum seeking control: a systematic design framework. Design of engineered systems whose operation is "best" or optimal in some sense is essential in tackling a range of socio-economic problems facing our society. This project will provide a methodology for design of such systems that would improve performance of various irrigation, optical communications, economics and power generation systems.
Information-theoretic secure communications via caching. This project aims to address the cybersecurity problem of securing telecommunication networks to prevent data leakage. Current widely-adopted data-encryption approaches to secure communications will be broken with large-scale quantum computers, and existing information-theoretic approaches rely on the channel quality of the network. To circumvent these risks, this project proposes a new information security approach using information cache ....Information-theoretic secure communications via caching. This project aims to address the cybersecurity problem of securing telecommunication networks to prevent data leakage. Current widely-adopted data-encryption approaches to secure communications will be broken with large-scale quantum computers, and existing information-theoretic approaches rely on the channel quality of the network. To circumvent these risks, this project proposes a new information security approach using information cached at devices to camouflage data. The project will future-proof secure communication systems against large-scale quantum computers, which threaten current encryption approaches. This should ensure that data transmitted over communication networks can never be revealed to interceptors or hackers, even in public WiFi.Read moreRead less

As the internet has become vital to our day-to-day working and living, we are witnessing a remarkable upsurge in the incidents of malicious software or malware on it. This project aims to develop key technologies that can precisely model the malware propagation on the internet. The technologies will help develop effective defence against malware propagation at an early stage, with limited defence resources, so as to minimise the damage and provide a capability to identify and control malware spreaders. This project is significant as it can secure the internet that is essential to the daily work of Australian people, thus addresses a fundamental problem in safeguarding Australia by protecting our critical infrastructure.Read moreRead less
Optimising throughput and Delay in network coded systems. This project addresses one main disadvantage of network coding: decoding delay. By solving this issue, we will unlock the true potential of network coding: delivery of high data rates in wireless and wireline networks. This will make network coding an attractive choice for live video streaming and mission-critical delay-sensitive applications.
Congestion control of networks: a unified stochastic framework. Systems such as the internet, wireless networks and the power grid require efficient allocation of shared resources. This research will develop ways to reduce delays in the internet and allow for growth in the power grid, without requiring additional infrastructure.
