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
  • Future Transportation Security: authentication in vehicular network, cyber security of electric vehicles
  • 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.
