My research interests include:

My on-going projects are:

  • Cybersecurity Challenge Platforms
  • Hardware security (Fault injection attacks, Meltdown & Spectre)
  • Website fingerpriting attacks and defenses
  • Mobile networking (Secure Wi-Fi, Indoor localization, Mobile hotspot)
  • Software defined radio & Wireless steganography

I lead the Mobile Computing Research Laboratory (MCRL) at Cleveland State.

Research Highlights:

  • We received the grant award from the National Science Foundation (NSF) on our research work on cybersecurity challenge platform. This will be used to train future cybersecurity professionals in both the technical hands-on IT skills and the legal and policy and legal issues. Cybersecurity scenarios we implement and investigate include EternalBlue ransomware attack, Meltdown, #OpJustina DDoS attack, and Hacking group Thallium. (NSF; May 2021 – April 2024; 400K)
  • We received the grant award from the Ohio Space Grant Consortium (OSGC) for the development of individualized, integrative, and progressive electronics laboratory course. This project creates a set of experiments of advanced electronics, e.g., bioelectronics and SRAM PUF (physically unclonable function), that enables students to see the curriculum as exciting and relevant to life outside of school. (OSGC; January 2021 – October 2021)
  • We received the grant award from the NSF to develop CS pathways as a part of the nation-wide CSforAll initiative. The Cleveland Tech Talent Pipeline is a Research-Practitioner Partnership (RPP) that will build upon several NSF-supported efforts in Cleveland to develop pathways for students in computer science and information technology from high school to career, community college and/or four-year colleges and universities. (NSF; November 2020 – October 2024; $2M)
  • Our paper, entitled Delay-Conscious Defense Against Fingerprinting Attacks, has been selected to present at The Nineteenth International Conference on Networks (ICN 2020), Lisbon, Portugal, in February, 2020. Website fingerprinting attacks are an Internet censorship technology and many attack and defense mechanisms have been proposed in the literature. The proposed defense algorithm maintains the high defense performance while reducing the page loading time, which has been identified as the weakness in previous mechanisms.
  • We received the grant award from the NSF for the research and education of cybersecurity systems. This project is intended to provide a holistic view on information and software security as well as hardware security. In particular, hardware security attacks such as hardware IP piracy, side-channel analysis, fault injection, and clock glitching are a growing concern to both semiconductor industry as well as end users. Our work is based on Altera FPGA prototyping systems and Quartus. (NSF TUES program; September 2013 – August 2019)
