This project aims to explore practical privacy-preserving solutions for cloud data mining-as-a-service based on the Intel Software Guard Extensions (SGX) technology. The research addresses privacy concerns of users when outsourcing data mining needs to the cloud. These concerns have increased as more businesses evaluate data mining-as-an outsourced service due to lack of expertise or computation resources. The expected outcomes from the research will include new data privacy models, new privacy-preserving data mining algorithms, and a prototype of cloud data mining software. These will help businesses cut costs for data mining and privacy protection, and provide significant benefits toward helping Australia achieve its national cyber security strategy and potentially provide economic impact from commercialisation of new software technology for the industry partner.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.

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
Security for Web Services. Web services, an emerging distributed computing paradigm, poses challenging problems in security, due to their dynamic decentralised scalable nature, operating over an untrusted Internet, for which no adequate solutions exist today. This research addresses the model, architecture and design of secure authorisation for web services. It achieves conceptual advances in terms of a flexible authorisation model, proposes a new XML based policy language, develops a comprehens ....Security for Web Services. Web services, an emerging distributed computing paradigm, poses challenging problems in security, due to their dynamic decentralised scalable nature, operating over an untrusted Internet, for which no adequate solutions exist today. This research addresses the model, architecture and design of secure authorisation for web services. It achieves conceptual advances in terms of a flexible authorisation model, proposes a new XML based policy language, develops a comprehensive security policy management framework, designs a distributed authorisation service and demonstrates a practical secure web service system in .NET.It presents a new approach to formally reasoning about conflict resolution policies with dynamic delegation.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

Efficient Multi-key Homomorphic Encryption and Its Applications. Multi-key homomorphic encryption (MKHE) is a key technology that functions to allow multiple users to supply their private input for collaboration in the cloud while keeping the user data confidential. Unfortunately, it is very difficult to obtain efficient MKHEs. This project aims to overcome this challenge by enabling novel efficient MKHEs. The expected outcomes of this project are to develop innovative cryptographic technologies ....Efficient Multi-key Homomorphic Encryption and Its Applications.

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
