  • Hong Lai, Mingxing Luo, Josef Pieprzyk, Lei Pan, Mehmet A. Orgun, Analysis of Weighted Quantum Secret Sharing based on Matrix Product States, Quantum Information Processing, Springer (accepted 29 October 2020, CORE rank B). One of the reviewers gives a short summary of the paper:  “The paper discusses the issue of weight allocation under the scenario of multiple participants, proposes the weighted quantum secret sharing schema based on tensor representation and matrix product states, as well as analyzes the security performance. The manuscript shows the complete theoretical deduction and  promotes quantum secret sharing.”
  • Mehwish Nasim: Full paper got accepted at IEEE/ACM International conference series on Advances in Social Network Analysis and Mining entitled: “A method to evaluate the reliability of social media data for social network analysis”. Joint work with DST, Uni Melbourne and Uni Adelaide. ASONAM is a top multidisciplinary conference, where top people from the field regularly publish.


  • Let’s meet one of our students: Cong Zuo

‘I am a Ph.D. student at Monash University and funded by Data61 and Monash University. My university supervisors are Joseph Liu and Shifeng Sun, and my Data61 supervisor is Josef Pieprzyk.

My research interest is on cybersecurity, in particular Database Security, Data Privacy, Cloud Security and Applied Cryptography. During my Ph. D. study, I mainly focus on developing new and advanced data privacy protocols such as searchable symmetric encryption (SSE), which enables the cloud to search any encrypted data without knowing the content and the query while preserving practicality and efficiency.  Currently, I try to explore other de-centralized encrypted database systems, such as those implemented with blockchain. Very recently, I am also actively involved in the research of privacy-preserving contact tracing, which will have an important impact on society during the outbreak of COVID-19. I have published a number of papers in top security conferences or journals such as ACM CCS, ESORICS, IEEE Trans. Dependable and Secure Computing, etc.  Until today, I have received more than 400 citations, and my H-index is 7, according to Google Scholar. In terms of Data61 experience, I receive much support from Data61. Apart from the generous financial support, my data61 supervisor, Josef Pieprzyk, gave me many suggestions regarding paper preparation. Moreover, he helped me to polish my papers. I really appreciate the help that he gave me. I also love the atmosphere of the Docklands site, and the people there are amiable. In addition, they helped a lot when I was there, and I would like to thank them for their valuable help.’ Cong.


  • let’s meet one of our Research Scientists


Our DSS group, along with the Cyber Security CRC, is collaborating with DST to deliver expertise in sovereign algorithm development, critical evaluation and customisation of exported solutions

New starters:

  • Meisam Mohamady joined our IoT team. Welcome Meisam.
  • Diethelm Ostry and Wei Liu joined DSS. Welcome to them both.
  • Tom Roth has joined us as a new PhD student from UTS Sydney. Welcome Tom.












One of our new research called DangerousCloak reveals it’s possible to backdoor the object detectors to digitally disappear from camera detection with relative ease. The project, led by Sharif Abudbba and Garrison Gao, in collaboration with the Cyber Security Cooperative Research Centre (CSCRC) and South Korea’s Sungkyunkwan University, on Adversarial Machine Learning has been widely picked up in international and national medias.

  • Cutting Edge Science and Engineering Symposium: Advances in personalised healthcare and wellbeing support technologies

The Human Centric Security team was successful in being awarded a Cutting Edge Science and Engineering Symposium award for 2019/2020.

The symposium “Advances in personalised healthcare and wellbeing support technologies” will be held virtually, on the 19/11 and 20/11/20. For registration and more information visit: Link

  • Join us for our next SAO seminar: our-sao-seminars
  • Humans And Cyber Security (HACS2020) workshop.

The second IEEE Humans and Cyber Security (HACS-2020) workshop will be a virtual workshop on the 2nd of December 2020 (EDT), again co-hosted with IEEE CIC (Collaboration and Internet Computing), IEEE CogMI (Cognitive Machine Intelligence) and IEEE TPS (Trust, Privacy and Security of Intelligence Systems, and Applications).

Keynote Speaker: Professor Debi Ashenden

Debi holds the DST Group-University of Adelaide Chair in Cybersecurity. In addition, she is Professor of Cyber Security at the University of Portsmouth (UK) and a visiting Professor at Royal Holloway, University of London (UK).  Debi’s research interests are in the social and behavioural aspects of cyber security – particularly in finding ways of ‘patching with people’ as well as technology. She is currently researching the socio-technical issues around cloud computing and DevSecOps, as well as exploring the implications of algorithmic decision-making.

Debi was previously Head of the Centre for Cyber Security at Cranfield University at the Defence Academy of the UK and was a member of the UK MOD’s Defence Science Expert Committee.  She has worked extensively across the public and private sector for organisations such as UK MOD, GCHQ, Cabinet Office, Home Office, Euroclear, Prudential, Barclaycard, Reuters and Close Bros. She has had a number of articles on cyber security published, presented at a range of conferences and co-authored a book for Butterworth Heinemann, Risk Management for Computer Security: Protecting Your Network & Information Assets.
