Design and deployment of practical anonymous access systems. This project aims to design, test and deploy a practical and highly secure anonymous access system for online businesses that offer services on a free trial basis. Currently, online businesses are unable to take advantage of feedback from customers during and after trial periods; nor do currently available mechanisms offer practical privacy protection to customers. The project expects to overcome these barriers by developing innovative ....Design and deployment of practical anonymous access systems. This project aims to design, test and deploy a practical and highly secure anonymous access system for online businesses that offer services on a free trial basis. Currently, online businesses are unable to take advantage of feedback from customers during and after trial periods; nor do currently available mechanisms offer practical privacy protection to customers. The project expects to overcome these barriers by developing innovative cryptographic solutions and security testing methods that will inform new protocol design and implementation, which will bring long-term benefits to online businesses and their customers. The project also aims to develop new, distributed ledger technology, which is a strategic technology trend. This will provide significant benefits such as a practical, reliable and highly secure anonymous access system for online businesses, in Australia and worldwide, that offer services on a free trial basis, which would enable these service providers to add value to and enhance their product offerings.Read moreRead less
Secure Crowdsourcing Classification with Privacy Protection against Servers. This project aims to enable comprehensive quality data classification via secure crowdsourcing. The quality of a data-intensive process, such as a Machine Learning algorithm, depends on the input data quality. By using a crowdsourcing classification, the project expects to overcome the painstaking and costly process of humans correctly annotating extensive input data from diverse real information. The expected outcomes ....Secure Crowdsourcing Classification with Privacy Protection against Servers. This project aims to enable comprehensive quality data classification via secure crowdsourcing. The quality of a data-intensive process, such as a Machine Learning algorithm, depends on the input data quality. By using a crowdsourcing classification, the project expects to overcome the painstaking and costly process of humans correctly annotating extensive input data from diverse real information. The expected outcomes are innovative technologies, guaranteeing accuracy and confidentiality of annotation results whilst protecting the privacy of data classification results. It enhances data-intensive outputs quality, which will benefit large data-intensive applications, such as cybersecurity protections via intrusion detection.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. 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 which realise efficient MKHEs, together with their cryptographic libraries and practical applications in solving industry problems. This will provide direct economic benefits to Australian industry through the enablement of advanced technologies and low-cost business solutions which are developed in Australia.Read moreRead less

However, existing approaches for enabling blockchain applications, particularly with privacy protection and anonymity, are vulnerable to quantum computer attacks. This project aims to enable novel cryptographic mechanisms together with their cryptographic libraries for protecting blockchain in the quantum world, hence, post-quantum secure blockchain. The expected outcomes of this project include innovative technologies, as well as secure and practical post-quantum protocols for protecting future blockchain applications. This will provide economic and social benefits to Australian industry through the enablement of advanced technologies which are developed in Australia.Read moreRead less

Summary
A Scalable and Adaptive-Resilient Blockchain. This project aims to address the security and scalability challenges that limit blockchain adoption. Existing blockchains do not scale and are vulnerable to attacks (e.g. with a total loss of over US$1 billion in 2019). This project expects to improve security by adaptively enforcing the currently broken security assumptions, and to improve scalability by designing blockchains with high concurrency via relaxed criteria on the ordering of transactions ....A Scalable and Adaptive-Resilient Blockchain. This project aims to address the security and scalability challenges that limit blockchain adoption. Existing blockchains do not scale and are vulnerable to attacks (e.g. with a total loss of over US$1 billion in 2019). This project expects to improve security by adaptively enforcing the currently broken security assumptions, and to improve scalability by designing blockchains with high concurrency via relaxed criteria on the ordering of transactions. The expected outcomes include foundations and practical solutions for self-adaptive, secure and scalable blockchains. The benefits of this would be improved confidence in and capacity for building blockchain applications, which have a predicted value of over US$3.1 trillion by 2030.Read moreRead less

Printable technologies for high security documents and consumer products. This project aims to develop two next-generation printable security feature technologies to protect users from counterfeiting, which costs the world economy billions in lost revenue and undermines the security of citizens. First, it aims to enhance the security of banknotes by developing printable active device patches with energy harvesting flexible polymers as a power source and thin film graphene/polymer nanomaterial as an electrode/energy storage media. Second, it aims to design invisible carbon nanotube inks for optical authentication via near infrared activation. Both technologies are expected to thwart sophisticated counterfeits, particularly those supported by organised crime.Read moreRead less
Detecting the invisible. The most easily sourced weapons of the terrorist contain conventional explosives such as TNT and Semtex. This project concerns the development of sensing materials and protocols that can give selective, sensitive, real time sensing of explosive analytes that will lead to an increase in the nation’s security.
A portable sensor for explosives. The National Research priority, safeguarding Australia, recognises that there is a real threat of terrorism and the need to protect Australians at home and abroad. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. The ability to detect trace amounts of explosives is therefore required. This means that there is a real need for a portable detection ....A portable sensor for explosives. The National Research priority, safeguarding Australia, recognises that there is a real threat of terrorism and the need to protect Australians at home and abroad. Although there is often talk of dirty bombs, and biological and nuclear terrorism, the most easily sourced weapon of the terrorist is still the conventional explosive. The ability to detect trace amounts of explosives is therefore required. This means that there is a real need for a portable detection system with the ability to reliably sense a specific explosive selectively at low concentrations. This project concerns the development of a new handheld sensor that has the potential to increase the nation's security.Read moreRead less
