Security for Web Services. Web services, an emerging distributed computing paradigm, poses challenging problems in security, due to their dynamic decentralised scalable nature, operating over an untrusted Internet, for which no adequate solutions exist today. This research addresses the model, architecture and design of secure authorisation for web services. It achieves conceptual advances in terms of a flexible authorisation model, proposes a new XML based policy language, develops a comprehens ....Security for Web Services. Web services, an emerging distributed computing paradigm, poses challenging problems in security, due to their dynamic decentralised scalable nature, operating over an untrusted Internet, for which no adequate solutions exist today. This research addresses the model, architecture and design of secure authorisation for web services. It achieves conceptual advances in terms of a flexible authorisation model, proposes a new XML based policy language, develops a comprehensive security policy management framework, designs a distributed authorisation service and demonstrates a practical secure web service system in .NET.It presents a new approach to formally reasoning about conflict resolution policies with dynamic delegation.Read moreRead less
Information Security Evaluation of Embedded Computer Software. Safeguarding classified electronic communications is of major national importance.

Safeguarding classified electronic communications is of major national importance. This research, into security evaluation of computer software, is supported by the Defence Signals Directorate, which verifies the security of communications devices used by Australia's government and armed forces. As such devices become increasingly sophisticated, traditional security evaluation techniques have become unacceptably difficult and costly. Hardware evaluation techniques, based on tracing paths through circuitry diagrams, have proven unsuitable for software evaluations. Consequently, devising new tools and techniques for information security evaluation of embedded computer software is essential for preserving Australia's national security.Read moreRead less
Security for Peer-to-Peer Systems. The importance of adequate security for Internet and online services has been underscored by recent events. The protection of information infrastructures in this ever-increasing digital world has become essential for businesses, governments and individuals.

Trust-Oriented Social Relation Analysis and Social Relation Aware Rating Analysis in Trust Management. Trust management is an emerging field offering critical challenges on evaluating the quality and trustworthiness of objects, services and raters. Thus it requires the development of novel techniques and solutions to address these challenges both conceptually and practically. This project will develop innovative techniques to infer trust in complex social networks, detect bias in trust ratings a ....Trust-Oriented Social Relation Analysis and Social Relation Aware Rating Analysis in Trust Management. Trust management is an emerging field offering critical challenges on evaluating the quality and trustworthiness of objects, services and raters. Thus it requires the development of novel techniques and solutions to address these challenges both conceptually and practically. This project will develop innovative techniques to infer trust in complex social networks, detect bias in trust ratings and its dependencies with social relations. They can greatly contribute to breakthrough techniques enabling trust-oriented social network analysis and more objective trust management systems that can be transferred to the Australian IT industry to promote the trustworthiness of Web services and reduce monetary loss.Read moreRead less
