Privacy in Genetic Databases. With the recent advances in genetic and computer technology enormous databases containing genetic information have become available for research and other purposes. An example of such databases is the Icelandic Health Database containing health and genetic records about the total population of Iceland. This has raised many privacy and ethical questions both among health professionals and the general public. Many agree that genetic information bears more ethical and ....Privacy in Genetic Databases. With the recent advances in genetic and computer technology enormous databases containing genetic information have become available for research and other purposes. An example of such databases is the Icelandic Health Database containing health and genetic records about the total population of Iceland. This has raised many privacy and ethical questions both among health professionals and the general public. Many agree that genetic information bears more ethical and privacy concerns than other health databases. In this project we shall investigate privacy and ethical issues connected to genetic information and we develop techniques to prevent a disclosure of individual values through statistical analysis.Read moreRead less
Algebraic Models of Stream Ciphers. 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 ....Algebraic Models of Stream Ciphers. 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
Security Services for Stream-Oriented and Multicast-Based Communication. Multicast communication over lossy networks is becoming the basic for a growing number of aplications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. This project is concerned with two major security problems of multicast communications: authentication and secrecy. The goal of this project is to: (1) deve ....Security Services for Stream-Oriented and Multicast-Based Communication. Multicast communication over lossy networks is becoming the basic for a growing number of aplications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. This project is concerned with two major security problems of multicast communications: authentication and secrecy. The goal of this project is to: (1) develop a framework for analysis and evaluation of security services for multicast communication; (2) design efficient algorithms and protocols for securing emerging applications that are multicast-based and/or stream-oriented.

Applications for large format video surveillance are about to grow rapidly, starting with military applications and then moving into the civilian arena, highlighting the importance of compression for interactive dissemination, so as to make best use of limited communication channels. This project will develop an innovative representation for motion and depth/elevation maps, which addresses a key obstacle in the deployment of technology for efficient interactive access to large format video and geospatial imagery. These applications are relevant to Australia's defence and infrastructure for smart information use. Moreover, this is a strategic proposal to strengthen Australia's existing lead in aspects of interactive media dissemination.Read moreRead less
