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
Security Services for Stream-Oriented and Multicast-Based Communication. Multicast communication over lossy networks is becoming the basic for a growing number of aplications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. This project is concerned with two major security problems of multicast communications: authentication and secrecy. The goal of this project is to: (1) deve ....Security Services for Stream-Oriented and Multicast-Based Communication. Multicast communication over lossy networks is becoming the basic for a growing number of aplications. It is therefore critical to provide sound security mechanisms for multicast communication. Yet, existing security protocols for multicast offer only partial solutions. This project is concerned with two major security problems of multicast communications: authentication and secrecy. The goal of this project is to: (1) develop a framework for analysis and evaluation of security services for multicast communication; (2) design efficient algorithms and protocols for securing emerging applications that are multicast-based and/or stream-oriented.

Information security and digital watermarking with Latin squares. The importance of digital information is increasing constantly. Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project ad ....Information security and digital watermarking with Latin squares. The importance of digital information is increasing constantly. Audio, video, and still image data dominate our daily lives. Such information has commercial and strategic importance. It is invaluable in crime prevention: for example, video from security cameras. The protection of commercially valuable material against piracy and sensitive information against security breaches is vital to our economy and our safety. This project addresses these issues, by developing new, secure watermarks and fingerprints to protect digital information. Such watermarks can also protect radio communication channels, which is important due to the rising demand for wireless connectivity.Read moreRead less
Enhancing Privacy for Digital Communication. Protecting one's privacy in cyber world is a challenging task. Every contact to a Web server leaves a digital footprint that can be linked with other publicly available information to compile a profile of one's activities. Anonymous communication is a powerful tool for enhancing individuals' privacy and providing services such as electronic election where a person's vote must be unlinkable to him/her. However, anonymity may be misused by criminals to ....Enhancing Privacy for Digital Communication. Protecting one's privacy in cyber world is a challenging task. Every contact to a Web server leaves a digital footprint that can be linked with other publicly available information to compile a profile of one's activities. Anonymous communication is a powerful tool for enhancing individuals' privacy and providing services such as electronic election where a person's vote must be unlinkable to him/her. However, anonymity may be misused by criminals to hide their identities and engage in illegal activities. The aim of this project is to design and analyse privacy enhancing communication systems that balance individuals' privacy and accountability, and develop criteria and metrics to compare performance of these systems.Read moreRead less
