Mi ZhangAssistant Professor Mi Zhang is part of the research team led by Guan-Hua Tu, Assistant Professor of Computer Science and Engineering at Michigan State University which won the Best Paper Award at the IEEE Conference on Communications and Network Security (CNS) 2018 (May 31-June 1) in Beijing, China.  Congratulations!

The paper "The Dark Side of Operational Wi-Fi Calling Services" presents the first study on the security implication of the operational Wi-Fi calling services and state-of-the-art Wi-Fi calling devices. Its discovers four security vulnerabilities which stem from the design defects of Wi-Fi calling standards, operational slips of operators, and implementation issues of Wi-Fi calling devices The lessons learned from this work can help secure mobile/wireless ecosystem and facilitate the global deployment of Wi-Fi calling services, as well as provide new design insights for upcoming 5G networks.
