Bilinear pairings on elliptic curves are a new cryptographic tool and allow novel and improved applications in information security. For example, they have been proposed as a substitute of existing public key infrastructures, an essential element in electronic commerce and a secure Internet. The research will lead to an increase in fundamental knowledge in the area of practical implementation and secure applications of pairings. The results will benefit all users of electronic communications who require security for their information. This includes the financial industries, government, commerce and domestic users. It will also support many new product opportunities aligned with Motorola's business markets.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
Analysis and classification of malicious code. Malicious software such as viruses and worms directly attacks the security, privacy and integrity of Australian e-commerce, large databases and communication channels. The recent uptake of malicious software by organised crime has made finding effective countermeasures more urgent. Around 80% of the malicious code in circulation is disguised in some way. This significantly increases the difficulty of automated detection and delays analysis. Automate ....Analysis and classification of malicious code. Malicious software such as viruses and worms directly attacks the security, privacy and integrity of Australian e-commerce, large databases and communication channels. The recent uptake of malicious software by organised crime has made finding effective countermeasures more urgent. Around 80% of the malicious code in circulation is disguised in some way. This significantly increases the difficulty of automated detection and delays analysis. Automated classification and de-obfuscation technologies are a precondition to applying more sophisticated detection heuristics. The project will be instrumental in safeguarding Australia by protecting critical infrastructure and defending us from online organised crime and information warfare.Read moreRead less

Algebraic Methods in Design and Analysis of Stream Ciphers. The project investigates the problem of communication security in the mobile environment where both confidentiality and authenticity are of prime concern. Stream ciphers are a very natural choice in mobile environment as they provide an efficient cryptographic protection using a limited computing resources. We model stream cipher as a system of multivariate equations. In this approach, security of stream ciphers can be measured as the c ....Algebraic Methods in Design and Analysis of Stream Ciphers. The project investigates the problem of communication security in the mobile environment where both confidentiality and authenticity are of prime concern. Stream ciphers are a very natural choice in mobile environment as they provide an efficient cryptographic protection using a limited computing resources. We model stream cipher as a system of multivariate equations. In this approach, security of stream ciphers can be measured as the complexity of an algorithm that solves the appropriate system of equations. This project leads to new techniques for the design and analysis of stream ciphers.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

As more and more business opportunities are created over the Internet, dealing with network-based intrusions and denial of service (DoS) attacks is becoming increasingly critical (as witnessed recently last year). The proposed research addresses systematically the theory and analysis of DoS attacks and develops new techniques and practical solutions to counteract them. We will investigate a hybrid method to counteract DoS, propose a new technique to identify malicious packets in the Internet to handle distributed DoS, consider a new approach using smart packets and develop enhancements to intrusion detection systems using data mining. Proposed techniques are analysed in practical situations.Read moreRead less

Defence Against Phishing Attacks. Australian businesses and citizens are losing millions of dollars in cybercrimes every year. Rural and regional businesses depend on the integrity of their Internet banking service, and yet, cybercriminals are working hard to defraud these users. This project aims to build a reliable defence against phishing attacks which rely on social engineering to steal online identities, using intelligence gathered from the brazen trade of credentials in the public domain.
