Privacy-Preserving Classification for Big-Data Driven Network Traffic. Protecting sensitive information in large network traffic flows while ensuring data usability for classification emerges as a critical problem of increasing significance. Existing techniques do not work on highly heterogeneous traffic from big-data applications for both privacy protection and classification (such as port-based and load- based methods). This project investigates new theories, methods and techniques for solving ....Privacy-Preserving Classification for Big-Data Driven Network Traffic. Protecting sensitive information in large network traffic flows while ensuring data usability for classification emerges as a critical problem of increasing significance. Existing techniques do not work on highly heterogeneous traffic from big-data applications for both privacy protection and classification (such as port-based and load- based methods). This project investigates new theories, methods and techniques for solving this problem. It proposes to develop a set of effective methods for privacy-preserving data publication through combining randomisation with anonymisation, and for classifying the published data through uncertainty leveraging by probabilistic reasoning and accuracy lifting by inter-flow correlation analysis and active learning.Read moreRead less
Novel audio watermarking techniques for tracing multimedia piracy. This project aims to develop inaudible, high-capacity audio watermarking techniques to trace the illegal copying and distribution of multimedia data containing a sound component, such as audios and sound videos.

This has led to strong demand for new techniques to ....Novel audio watermarking techniques for tracing multimedia piracy. This project aims to develop inaudible, high-capacity audio watermarking techniques to trace the illegal copying and distribution of multimedia data containing a sound component, such as audios and sound videos. With the rapid growth of communication networks and the use of advanced multimedia technology, digital multimedia data can be easily copied, manipulated and distributed. This has led to strong demand for new techniques to prevent illegal use of copyrighted data. The project is expected to advance the theory of audio watermarking and enhance Australia's international competitiveness in this field.

This project aims to develop an innovative data sharing system, with a mathematically provable privacy guarantee, in a cloud environment. This will be adopted by Australian Education Management Group’s (AEMG) cloud campus to exchange data in a restricted privacy manner between partner institutions. It will be commercialised as a middleware that can be plugged into existing cloud environments to maintain required privacy even when the cloud crosses various jurisdictions with different privacy policies. The outcomes will benefit educational organisations, and lay the foundations for data sharing in other communities such as the government, banks, and other industries in Australia.Read moreRead less

Summary
Priced attribute-based encryption and its applications. This project aims to develop Priced Attribute-Based Encryption (PABE), a security mechanism. Access control is important for secure online information access. Access to encrypted data requires both private key and payment from earmarked funds specified by the access policy of encrypted data. This research will enable both authorisation and restriction of users while they access protected data anonymously. Expected outcomes include new model ....Priced attribute-based encryption and its applications. This project aims to develop Priced Attribute-Based Encryption (PABE), a security mechanism. Access control is important for secure online information access. Access to encrypted data requires both private key and payment from earmarked funds specified by the access policy of encrypted data. This research will enable both authorisation and restriction of users while they access protected data anonymously. Expected outcomes include new models, theories, techniques and PABE constructions. This research project is expected to contribute to cyber security in anonymous access control with advanced management for all Australians.Read moreRead less
Secure and dynamic access control over encrypted data in the cloud. This project aims to enable dynamic access control due to organisational change, which is critical to enable the adoption of cloud computing in practice. Access control over encrypted outsourced data is an essential requirement for enabling practical, secure storage.

This project aims to enable dynamic access control due to organisational change, which is critical to enable the adoption of cloud computing in practice. Access control over encrypted outsourced data is an essential requirement for enabling practical, secure storage. This project will be underpinned by a study of constructing new cryptographic primitives for enabling cipher-text changes without the need for refreshing the users’ secret keys. The expected outcomes will bridge theory and practice, providing economic benefits to industry by enabling practical mechanisms to store confidential user’s information in the cloud, hence lowering the infrastructure cost for industry.Read moreRead less
Design and deployment of practical anonymous access systems. This project aims to design, test and deploy a practical and highly secure anonymous access system for online businesses that offer services on a free trial basis. Currently, online businesses are unable to take advantage of feedback from customers during and after trial periods; nor do currently available mechanisms offer practical privacy protection to customers. The project expects to overcome these barriers by developing innovative ....Design and deployment of practical anonymous access systems. This project aims to design, test and deploy a practical and highly secure anonymous access system for online businesses that offer services on a free trial basis. Currently, online businesses are unable to take advantage of feedback from customers during and after trial periods; nor do currently available mechanisms offer practical privacy protection to customers. The project expects to overcome these barriers by developing innovative cryptographic solutions and security testing methods that will inform new protocol design and implementation, which will bring long-term benefits to online businesses and their customers. The project also aims to develop new, distributed ledger technology, which is a strategic technology trend. This will provide significant benefits such as a practical, reliable and highly secure anonymous access system for online businesses, in Australia and worldwide, that offer services on a free trial basis, which would enable these service providers to add value to and enhance their product offerings.Read moreRead less
Post-Quantum Functional Encryption : Principles, Protocols and Practice. Modern cryptography has the power to revolutionise virtually every aspect of our online lives. Large-scale secure data sharing could become a breeze, with tools such as functional encryption (FE) to give us fine control over access rights by means of expressive languages, and there will be no more juggling of crypto keys. Finally, the known foundations of FE will crumble when even small-sized quantum computers become realit ....Post-Quantum Functional Encryption : Principles, Protocols and Practice. Modern cryptography has the power to revolutionise virtually every aspect of our online lives. Large-scale secure data sharing could become a breeze, with tools such as functional encryption (FE) to give us fine control over access rights by means of expressive languages, and there will be no more juggling of crypto keys. Finally, the known foundations of FE will crumble when even small-sized quantum computers become reality, perhaps next decade. This project aims to recreate and expand the power of FE from post-quantum (PQ) mathematical principles, immune to quantum attacks, building on recent discoveries of limited forms of PQ-FE from rock-solid crypto principles. It begs exploring, for the truly spectacular outcomes likely to ensue.Read moreRead less
