内容摘要：Various large datasets are being constantly generated, collected, and stored by organizations of all sizes today. Along with the growing data is the increasing amount of private and sensitive information that must be carefully managed and properly secured. Traditional approaches for securing the data by encryption usually fall short of fulfilling the purpose, as they naturally prevent any meaningful operations, in particular searching capability over the encrypted data. On the other hand, supporting fast and versatile search for effective information retrieval is indispensable when working with any large datasets, and it has been ubiquitously demanded in almost every big data storage system today. In this talk, we will survey encrypted search designs that have received wide attentions recently for their potential to address the fundamental conflict between encrypted data storage and search. Among the wide range of literature in this area, we will introduce and carefully examine a number of noteworthy designs as well as some of our own early research efforts, with focus on their tradeoffs among functionality, efficiency, and security. We will also illustrate some remaining challenging issues that are currently hindering the deployment of encrypted search over large datasets in practice. Finally, we will discuss some possible solution directions to tackle the challenges.

内容摘要：Cyberspace is now a critical battle ground for attacks and defences at personal and national level. However, cybersecurity is a mainly uncharted territory, and we have far more questions than answers from applications all the way to theories. In this talk, we firstly report the work we have done about attack and defence in cyberspace. Secondly, we present the problems and challenges that we are facing, e.g., big data security and privacy, and discuss the possible directions in the fields.
个人简介：Shui YU is currently a Senior Lecturer of School of Information Technology, Deakin University. He is a member of Deakin University Academic Board (2015-2016), a Senior Member of IEEE, and a member of AAAS and ACM, the vice chair of Technical Subcommittee on Big Data Processing, Analytics, and Networking of IEEE Communication Society, and a member of IEEE Big Data Standardization Committee.
Dr Yu’s research interest includes Security and Privacy in Networking, Big Data, and Cyberspace, and mathematical modelling. He has published two monographs and edited two books, more than 150 technical papers, including top journals and top conferences, such as IEEE TPDS, IEEE TC, IEEE TIFS, IEEE TMC, IEEE TKDE, IEEE TETC, and IEEE INFOCOM. Dr Yu initiated the research field of networking for big data in 2013. His h-index is 22.
Dr Yu actively serves his research communities in various roles. He is currently serving the editorial boards of IEEE Communications Surveys and Tutorials, IEEE Access, and a number of other international journals. He has served more than 70 international conferences as a member of organizing committee, such as publication chair for IEEE Globecom 2015, IEEE INFOCOM 2016 and 2017, TPC co-chair for IEEE Big Data Service 2015, IEEE ATNAC 2014 and 2015.
