Efficient and Secure Word-Based Stream Ciphers for Wireless Communications. Wireless networks are increasingly being used for communication, and to manage and control Australia's critical infrastructure. However, current methods of securing wireless networks are flawed, putting the country's economy, environment, and citizens at risk. The most reliable method for protecting wireless communications requires secure and efficient encryption algorithms.

Wireless networks are increasingly being used for communication, and to manage and control Australia's critical infrastructure. However, current methods of securing wireless networks are flawed, putting the country's economy, environment, and citizens at risk. The most reliable method for protecting wireless communications requires secure and efficient encryption algorithms. However, flaws have been found in most algorithms proposed to date. This project will examine existing algorithms and attacks to determine design criteria for secure encryption algorithms for use in a wireless environment. An algorithm which meets these criteria and can be implemented efficiently in hardware and software will be proposed.Read moreRead less
Space-Time Coding and Receiver Structures for High Speed Wireless Communications. The aims of the project are to to devise space-time coding techniques and cost effective receiver structures for applications in future wireless data networks. We expect that new space-time codes would enable an increase in spectral efficiency by two orders of magnitude compared with the existing systems and allow the introduction of advanced multimedia services.

Closing the Gap: Fundamental Capacity Limits for Interfering Wireless Networks and Practical Methods to Get There. Enhancing communication networks to achieve broadband data rates is now a national priority. Wireless communications is hugely important, with mobile phones, wireless computers, and wireless Internet access to homes, all rapidly growing areas.

Enhancing communication networks to achieve broadband data rates is now a national priority. Wireless communications is hugely important, with mobile phones, wireless computers, and wireless Internet access to homes, all rapidly growing areas. This project addresses the fundamental bottleneck of interference between links in wireless networks. Wireless unplugs the user and allows him/her to roam, and to set up ad-hoc networks with other users. This research will thus contribute to Australia's increased productivity. Just as importantly, this project addresses fundamental research; it will increase Australia's knowledge base and provide training for students and researchers in how to think about communications problems.Read moreRead less

channel uncertainty at the receiver, and the impact of multiple access
interference. This research will provide new directions for the design
