Within Australia, it is estimated that th ....Software Quality Improvement Through Static Analysis and Annotation. Software forms the basis of critical infrastructure that supports industries such as electronic commerce. Flaws in the software can lead to failure of the overall system, or allow the security mechanisms of the software to be by-passed. This project is developing methods to improve the quality of software by finding common flaws that lead to security vulnerabilities or runtime failures. Within Australia, it is estimated that there are approximately 75,000 software developers who make substantial use of C/C++ and who could benefit from the availability of better automatic static analysis tools to improve both the quality of the code they produce and their productivity.Read moreRead less

Transaction Oriented Computational Models for Multi Agent Systems. Agent systems are a very promising technology for constructing complex, large-scale software. Australian researchers have made key
contributions in this area, particularly with reference to one mature and commonly adopted agent architecture known as BDI (Belief, Desire, Intention). To make this technology suitable for use in advanced applications, it has to be provided with robust and predictable behaviour. This project wil ....Transaction Oriented Computational Models for Multi Agent Systems. Agent systems are a very promising technology for constructing complex, large-scale software. Australian researchers have made key
contributions in this area, particularly with reference to one mature and commonly adopted agent architecture known as BDI (Belief, Desire, Intention). To make this technology suitable for use in advanced applications, it has to be provided with robust and predictable behaviour. This project will address that need by designing and implementing a novel agent language for BDI, based on contributions using transactional concepts for agents developed at The University of Melbourne. This will contribute to the development of robust and predictable agent software, that can be used in complex and large scale applications of the future.

Derivation and timing analysis of concurrent real-time software. Safety-critical computer systems are commonly controlled by concurrent real-time software. Assurance of such systems requires rigorous methods for deriving the software and verifying its logical and timing correctness. This project will directly address this problem via a new paradigm for real-time programming that is based on a machine-independent concurrent real-time programming language, that explicitly represents timing deadlin ....Derivation and timing analysis of concurrent real-time software. Safety-critical computer systems are commonly controlled by concurrent real-time software. Assurance of such systems requires rigorous methods for deriving the software and verifying its logical and timing correctness. This project will directly address this problem via a new paradigm for real-time programming that is based on a machine-independent concurrent real-time programming language, that explicitly represents timing deadlines within programs. This allows a partitioning of the development process into a machine-independent phase that derives a program to meet a high-level specification, and a machine-dependent phase that checks that the timing deadlines within the generated machine code are guaranteed to be met.Read moreRead less
A formal foundation for security architecture. Security of computer systems is essential for the maintenance of privacy, confidentiality and integrity of personal, commercial and government data, and the trustworthiness of the computational devices that are embedded in critical societal infrastructure.

Security of computer systems is essential for the maintenance of privacy, confidentiality and integrity of personal, commercial and government data, and the trustworthiness of the computational devices that are embedded in critical societal infrastructure. However, current theoretical understanding of secure systems development is poor. The project will develop our understanding of an emerging approach to the design of secure systems and develop verification methods that may be applied to guarantee systems security. Its outcomes will contribute to processes for certifying systems at very high levels of security, a requirement in defence and government settings that will become increasingly significant in the commercial sector.Read moreRead less
Compilation of Specifications. Computer software now controls critical systems worldwide. International standards require such programs to be produced from mathematically-precise specifications, but the techniques and tools involved are highly complex and unfamiliar to most programmers. This project will show how a tool already used by software developers, the program compiler, can be extended to undertake much of the task automatically. This will be done by devising a compilation strategy, b ....Compilation of Specifications. Computer software now controls critical systems worldwide. International standards require such programs to be produced from mathematically-precise specifications, but the techniques and tools involved are highly complex and unfamiliar to most programmers. This project will show how a tool already used by software developers, the program compiler, can be extended to undertake much of the task automatically. This will be done by devising a compilation strategy, based on program refinement theory, that automatically translates specification statements in programs into executable code. Such an outcome will ultimately improve the speed, accuracy and cost-effectiveness of critical software development.Read moreRead less

The architecture of networks: Characterisation and visualisation of complex systems as fluctuating networks. Complex systems comprise many mutually interacting components, characterised by a range of different interactions over time and space. They are dynamical systems, whose features are reminiscent of a web, with fluctuating links of varying strengths. The natural paradigm for such systems is a generic network, or a graph. A suite of novel measures from statistical physics, graph theory, top ....The architecture of networks: Characterisation and visualisation of complex systems as fluctuating networks. Complex systems comprise many mutually interacting components, characterised by a range of different interactions over time and space. They are dynamical systems, whose features are reminiscent of a web, with fluctuating links of varying strengths. The natural paradigm for such systems is a generic network, or a graph. A suite of novel measures from statistical physics, graph theory, topology, geometry, and computer graphics will be developed to characterise system/graph growth and stability. The aim is two-fold: first to reduce real complex systems (mainly financial systems) to computationally manageable structures (including direct visualisation) and second to construct realistic models of the evolution of such systems.Read moreRead less

Modern computer software systems are required to operate in complex dynamic environments and to handle functioning of highly sensitive (security and safety-critical) organizations in government and commerce. Typical applications include air-traffic control systems, telecommunication networks, and banking systems. To ensure robustness, computationally predictable behaviour and trustworthiness of these systems, their designs and implementations must be formally well grounded. This is an important but difficult challenge. This project will systematically develop a framework by combining modal-logics to adequately capture and reason about temporal, epistemic and social aspects of dynamic and multi-agent systems. The combined logics would be evaluated on practical applications.
