Research Experience

Ph. D. Research Projects @ Centre for Infocomm Technology (INFINITUS), NTU, Singapore 10/2014-Present

  • Project Title “On Reliability Analysis of Smart Grids under Topology Attacks” 09/2016-Present
  • Developed a stochastic Petri net based analytical model to assess and analyze the system reliability of smart grids, specifically against topology attacks, and system countermeasures (i.e., intrusion detection systems and malfunction recovery techniques)
  • Topology attacks, evolving from false data injection attacks, are growing security threats to smart grids. Although it is challenging to detect this kind of coordinated attacks, yet careful investigations can be conducted to provide valuable insights for researchers to fight against them. Stochastic Petri net technique is employed to establish an analytical model in order to study the topology attacks and corresponding system behaviors in smart grids. Both transient and steady-state analysis are carried out with our developed analytical model to assess the system reliability under concurrent presence of topology attacks and system countermeasures.
  • Submitted one journal paper titled “On Reliability Analysis of Smart Grids under Topology Attacks: A Stochastic Petri Net Approach” in ACM Transactions on Cyber-Physical Systems (2017).

 

  • Project Title “Intrusion Detection for Opportunistic Attacks in Smart Grid Cyber-Physical System”11/2015-08/2016
  • Proposed a novel methodology for detecting opportunistic false command injection attacks in smart grid
  • Information forensics technique is employed to assess the local agents’ running status by analyzing and auditing the state data of the local grid. Long term observation and assessment is conducted to detect the opportunistic false command injection attacks launched by compromised local agents
  • Published one journal paper titled “DDOA: A Dirichlet-based Detection Scheme for Opportunistic Attacks in Smart Grid Cyber-Physical System” in IEEE Transactions on Information Forensics and Security (Nov. 2016)

 

  • Project Title “Behavior Rule-based Intrusion Detection in Smart Grid Cyber-Physical Systems” 10/2014-10/2015
  • Built a rule specification-based behavior model for IEDs’ operations, assess the IEDs’ behaviors by compliance levels with the predefined model, and detect the intrusion behaviors with an adaptive reputation system
  • Published one journal paper titled “Distributed Host-based Collaborative Detection for False Data Injection Attacks in Smart Grid Cyber-Physical System” in Journal of Parallel and Distributed Computing (May 2017), one book chapter titled “Behavior Rule Specification-based False Data Injection Detection Technique for Smart Grid” in book “Cyber Security for Industrial Control Systems: From the Viewpoint of Close-Loop” (Apr. 2016), and co-authored one journal paper titled “BLITHE: Behavior Rule Based Insider Threat Detection for Smart Grid” in IEEE Internet of Things Journal (Apr. 2016)
