In cloud/big dataera, individuals and industries are
encouraged tooutsource their data to "unknown" cloud so as to get rid of thecost of local data storage and management. The remote data storage andretrieval services supported by cloud allow users to gain access to dataanytime anywhere. However, they yield security and privacy concerns for usersas the data is out of "physical control". This talk will focus on thestudy of secure cloud-based data search, share and more (by leveraging somewell-studied cryptographic tools).
Dr Kaitai Liang isan Assistant Professor in Secure Systems at the University of Surrey, UK, andmember of the Surrey Centre for Cyber Security, a GCHQ recognised UK AcademicCentre of Excellence in Cyber Security Research. Kaitai received the PhD degreein computer science (applied cryptography direction) from City University ofHong Kong in 2014. Prior to SURREY, Kaitai was a Lecturer in School ofComputing, Mathematics and Digital Technology, Manchester MetropolitanUniversity; postdoctoral researcher at Department of Computer Science, AaltoUniversity (Finland); visiting scholar at Department of Computer Science, UCL;visiting scholar at KU LEUVEN (Belgium), Sapienza University of Rome (Italy)and University of Wollongong (Australia); research intern in Institute forInfocomm Research (Singapore). Kaitai has been involved in a few Europeanfunded projects. His main research interests are applied crypto, data security,big data security, blockchain, smart contract and privacy-enhancing technology.Kaitai has published a series of research works, applying secure tools totackle real-world problems, in many high tier international journals (e.g.,IEEE TIFS, IEEE NETWORK, and IEEE Transactions on Industrial Informatics).Kaitai has served as TPC for many renown international security/privacyconferences, e.g., ACNS, TRUSTCOM, ASIACCS, ACISP, ProvSec, and he was the pcchair of International workshop on Security in Big Data. Kaitai is also anofficial ISO member of UK ISO Crypto Sub Committee IST/33/2.
