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
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. This project will develop efficient and secure auction protocols using innovative approac ....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. 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

Cryptographic Protocols from Pairings: Proofs and Designs. Modern society has become critically dependent on information and communications infrastructures. At the same time, the development of e-commerce is being slowed by lack of confidence in its security. By providing increased assurance and enhanced cryptographic security protocols this research will improve the dependability of the nation's information and communications infrastructure, as well as encourage the growth of e-commerce. Throu ....Cryptographic Protocols from Pairings: Proofs and Designs. Modern society has become critically dependent on information and communications infrastructures. At the same time, the development of e-commerce is being slowed by lack of confidence in its security. By providing increased assurance and enhanced cryptographic security protocols this research will improve the dependability of the nation's information and communications infrastructure, as well as encourage the growth of e-commerce. Through the expertise and experience gained with this project, Australia's excellence in information security research will be reinforced. The training of PhD and Honours students will provide a much needed source of highly trained information security professionals.Read moreRead less
Security for Wireless Mobile Ad hoc Networks. Mobile ad hoc networks, a new emerging wireless networking paradigm, poses challenging problems in security, due to its dynamic nature and lack of centralised infrastructure, for which no adequate solutions exist today. This research addresses theory and design of secure mobile ad hoc networks.

Mobile ad hoc networks, a new emerging wireless networking paradigm, poses challenging problems in security, due to its dynamic nature and lack of centralised infrastructure, for which no adequate solutions exist today. This research addresses theory and design of secure mobile ad hoc networks. It achieves conceptual advances in terms of new security models for distributed location management, mobile authentication and multicasting; it proposes novel dynamic group key management and denial of service protection schemes, develops new security mechanisms for ad hoc routing, provides new insights into formal reasoning of security and demonstrates and evaluates practical secure wireless mobile applications.Read moreRead less
Privacy-preserving data processing on the cloud. 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 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

It is the first step for many everyday online processes such as remote login or electronic banking. This project aims to make analysis of such protocols more realistic and more complete, allowing online communication to become more secure for both corporate users and individuals.
Secure Electronic Voting with Flexible Ballot Structure. It is inevitable that electronic voting will eventually replace current paper based voting schemes. Despite considerable research no secure solution is available for an electronic voting scheme allowing complex election rules, such as preferential voting used in Australia. The main outcome of the research will be the fundamental knowledge required to develop general secure and flexible electronic voting schemes.

Despite considerable research no secure solution is available for an electronic voting scheme allowing complex election rules, such as preferential voting used in Australia. The main outcome of the research will be the fundamental knowledge required to develop general secure and flexible electronic voting schemes. The security aspects of the design will be thoroughly analysed to ensure that the integrity of the ballot is maintained without compromising user privacy. The practical aspects of implementing such a system will also be investigated and a prototype implementaion provided.Read moreRead less
