讲座题目（一）：Towards Secure Search over Large Encrypted Datasets
主讲人：Prof. Kui REN (IEEE Fellow, University at Buffalo, State University of New York)
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.

讲座题目（三）：Cybersecurity: Today and Tomorrow
主讲人：Dr. Shui YU（SMIEEE, School of Information Technology, Deakin University）
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.
