Personal profile

Biography

Joseph (Kai Sui) Liu is an Associate Professor in the Faculty of Information Technology, Monash University. He got my PhD from the Chinese University of Hong Kong at 2004. His research areas include cyber security, blockchain and applied cryptography. He has received more than 8500 citations and with more than 200 publications in top venues such as CRYPTO, ACM CCS, NDSS, INFOCOM.

He is currently the lead of the Monash Cyber Security Discipline Group. He has established the Monash Blockchain Technology Centre at 2019 and serve as the founding director. His remarkable research in linkable ring signature forms the theory basis of Monero (XMR), one of the largest cryptocurrencies in the world with current market capitalization more than US$2 billion.

He also serves as the Course Director of the re-branded Master of Cybersecurity, since 2020.

He has been given the prestigious ICT Researcher of the Year 2018 Award by the Australian Computer Society (ACS),  the largest professional body in Australia representing the ICT sector, for his contribution to the blockchain and cyber security community.

Research interests

My research mainly focuses on cyber security and applying various cryptographic technologies into real world systems. They include, but are not limited to:

  • Cloud Security: cloud data protection, privacy in cloud, cloud access control
  • Electronic Healthcare System Security: security and privacy
  • Blockchain: security, privacy-preserving features
  • Lightweight Security: cryptographic algorithms for lightweight device (e.g. sensors, RFID etc.)
  • Applied Cryptography: public key cryptography, identity-based cryptography, digital signature, attribute-based system, anonymous signature (e.g. group signature, ring signature) etc.
