Secure and Efficient Electronic Auctions. For the first time in history electronic commerce promises the possibility of auctions to decide the correct market price for a widespread variety of everyday goods and services. Security and efficiency are critical factors in making this a reality, but almost all the many protocols for secure auctions proposed to date suffer from extreme computational requirements.

For the first time in history electronic commerce promises the possibility of auctions to decide the correct market price for a widespread variety of everyday goods and services. Security and efficiency are critical factors in making this a reality, but almost all the many protocols for secure auctions proposed to date suffer from extreme computational requirements. This project will develop efficient and secure auction protocols using innovative approaches based on advanced cryptographic techniques. In particular we will pioneer the exploration of secure microauctions suitable for negotiating the price of small value goods and utilities in almost real time.Read moreRead less
Investigations Into New Public Key Systems. 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 computatio ....Investigations Into New Public Key Systems. 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
Secure Communications for Critical Infrastructure Control Systems. Control systems are crucial to the nation's critical infrastructure. They supervise and command the remote devices used in the energy distribution, water management, telecommunications, and transport industries. Historically, security has not been a concern in the design of control systems communications, which has resulted in their current vulnerable state. This project will establish the communications security requirements ....Secure Communications for Critical Infrastructure Control Systems. Control systems are crucial to the nation's critical infrastructure. They supervise and command the remote devices used in the energy distribution, water management, telecommunications, and transport industries. Historically, security has not been a concern in the design of control systems communications, which has resulted in their current vulnerable state. This project will establish the communications security requirements of control systems technologies and propose suitable secure communications schemes. New cryptographic protocols and analytic models will be developed to account for the criticality and operational peculiarities of control systems communications. These results are of significant potential value to Australia's critical infrastructure protection.Read moreRead less

Australia is faced with the challenge of engendering trust in, and protecting, the information systems vital to the economic and social development of the nation. This initiative will produce a national direction for research, development and educational activities in information security with particular emphasis on the protection of the national interest. It will do so by bringing together for the first time, academic, government and business people from a vast array of backgrounds, and whose interests lie across a spectrum of commercial, legal, policy and research outcomes.Read moreRead less
Technical and Legal Models for Virtual Info-Sharing Networks (VISN) for Critical Infrastructure Protection (CIP). This project has substantial national benefit because it will result in the design of a virtual information sharing network (VISN) that will better protect Australia's critical infrastructure. It will provide a comprehensive legal/technical analysis of the requirements/characteristics necessary for the development of a VISN. The development of a secure environment for a VISN will i ....Technical and Legal Models for Virtual Info-Sharing Networks (VISN) for Critical Infrastructure Protection (CIP). This project has substantial national benefit because it will result in the design of a virtual information sharing network (VISN) that will better protect Australia's critical infrastructure. It will provide a comprehensive legal/technical analysis of the requirements/characteristics necessary for the development of a VISN. The development of a secure environment for a VISN will improve industry trust and confidence in participating in the sharing of sensitive information; especially the disclosure of potential vulnerabilities or ascertained potential threats. The project will improve information dissemination speeds and assist post information disclosure controls. Read moreRead less

Timed Commitment Schemes to Smooth Internet Bottlenecks, Defend against Denial of Service Attacks, and Bypass Some Legal Problems of Enccryption. Bottlenecks on the Internet and Denial of Service attacks on a server are both caused by excessive demands made on a system. This proposal is to reduce the ill-effects of either by building on our previous theoretical work on strongboxes of combinatorial designs. In the case of bottlenecks, the demands are legitimate but badly timed, and our approach ....Timed Commitment Schemes to Smooth Internet Bottlenecks, Defend against Denial of Service Attacks, and Bypass Some Legal Problems of Enccryption. Bottlenecks on the Internet and Denial of Service attacks on a server are both caused by excessive demands made on a system. This proposal is to reduce the ill-effects of either by building on our previous theoretical work on strongboxes of combinatorial designs. In the case of bottlenecks, the demands are legitimate but badly timed, and our approach will redistribute the demands more evenly. In the case of Denial of Service attacks, the demands are malicious, and our approach will respond in such a way as to deplete the resources of the attacker.Read moreRead less

This project aims to address the current lack of privacy of user data processed by common cloud computing web servers, including email, business data, and confidential files. This project aims to develop new techniques in cryptography. The anticipated outcome is a suite of practical tools enabling common cloud computing processing operations such as search, statistical analysis, and multi-user access control, to be performed efficiently while preserving the data privacy. These tools should provide significant benefits to the privacy of cloud users, as well as financial and reputation benefits to the IT industry, by significantly reducing the likelihood of massive user data privacy breaches in the event of a cyber-hacking attack on the cloud server.Read moreRead less
