Public key cryptography is now mainstream technology and an essential tool in electronic business. In order to go beyond the basic security services of confidentiality and authentication, additional features are now desirable, such as verifiability of encryption, distributed key generation, and group-oriented encryption and signatures. At the same time the increasing demand for mobile business requires public key implementations with minimal computational and storage demands. This project will study five recently proposed public key algorithms and assess their suitability for various secure applications. These results are of significant potential value in Australia's electronic commerce market.Read moreRead less

Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission ....Development of a new transport layer protocol to provide secure broadband internet connections via satellite to rural and remote areas. Satellite links form an essential part of broadband connectivity to rural and remote areas. Effective use of the internet over satellite links is therefore essential if B2B (Business-to-Business) and B2C (Business-to-Consumer) E-commerce is to develop in these areas. In many application networks, particularly virtual private networks (VPN), secure transmission is important to avoid fraud and maintain privacy.
Satellite links introduce a long delay (latency) in the transmission path and existing secure internet protocols do not handle this well. This is because in many situations, it is a requirement that the secure connection be implemented not only independently of the
satellite service provider but also in a reliable and efficient way.
This project will develop new practical solutions so that secure and reliable end-to-end connections can be provided over the satellite links.

Distributed Denial-of-Service (DDoS) attacks are one of the most persistent and damaging threats to services on the Internet. In recent years, there has been widespread use of DDoS attacks for both financial and political advantage by attackers. The challenge for our Australian industry partner (PowerGuard Pty Ltd) is to continue to scale their DDoS defence platform so that it can be used in much higher bandwidth environments, such as carriers’ backbone networks, or large government and commercial networks that have multiple high-speed links to the Internet. The results of this project will provide an Australian company with a leading position in this important and growing market. Read moreRead less
High Bandwidth Efficient Schemes for Portable Multimedia Communications. The introduction of multimedia services for mobile users has resulted in a shortage of satellite spectrum.

The introduction of multimedia services for mobile users has resulted in a shortage of satellite spectrum. Spot beam technology is used to provide service in areas of high user density. Adjacent overlapping beams are allocated different frequency bands, however interference from neighbouring beams limits capacity. Multi-User Detection is a technology capable of significantly increasing capacity by frequency re-use in adjacent spot beams. The aim of this project is to investigate receiver design for multi-user spot-beam channels and develop associated synchronisation and channel estimation methods. The outcome will be efficient communications systems supporting higher user populations, without increasing the bandwidth required.Read moreRead less

Modems for portable radio terminals must take advantage of state-of-the-art digital communications in order to stay commercially competitive. In particular they need to utilize less bandwidth and power for a fixed data rate. The approach here is to employ a parallel configuration of highly efficient error control codes, together with bandwidth efficient continuous phase modulation (CPM). The theoretical performance of such a system is to be investigated using a novel information-theoretic technique, and the system will be optimised in terms of coding scheme and CPM complexity.Read moreRead less
