The project investigates communication security in the mobile environment where both confidentiality and authenticity are of a prime concern. 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
A novel cooperative global information system for healthcare. This project will develop a global model for healthcare based on the groundbreaking Protocol Hypothesis Testing (PHT) system, allowing expert groups of clinicians to create and share knowledge across organizations. The PHT is a unique functioning knowledge management system that allows clinicians to record patient and treatment data as it is generated in clinical practice and applies scientific methods to generate clinical knowledge, ....A novel cooperative global information system for healthcare. This project will develop a global model for healthcare based on the groundbreaking Protocol Hypothesis Testing (PHT) system, allowing expert groups of clinicians to create and share knowledge across organizations. The PHT is a unique functioning knowledge management system that allows clinicians to record patient and treatment data as it is generated in clinical practice and applies scientific methods to generate clinical knowledge, all in real-time. The project will develop and test a framework for the PHT system to be used cooperatively by expert groups across virtual organizations, refining the PHT system in the process.Read moreRead less

In e-Research environments, users need to have secure access to remote resources owned by different organisations. Since these resources are not directly under the control of e-Research applications, they need to negotiate with resource providers for access time, duration, and the level of quality of service expected to make sure that the interlinked operations are performed as required. This project develops information and communications technologies that enable the creation of such e-Research environments.Read moreRead less
