Jaejong Baek

Welcome, ^^

I am Dr. Jaejong Baek (called JJ) , at Arizona State University as a visiting researcher since Aug. 2016. My research topic focuses on the mobile and wireless network security system like WLAN, 3G, 4G/LTE, and Software Defined Network. Mostly, I'm trying to find vulnerabilities and countermeasures concerning those radio technologies.

Recently, my paper "Wi Not Calling: Practical Privacy and Availability Attacks in Wi-Fi Calling " has been accepted in ACSAC ’18, December 3–7, 2018, San Juan, PR, USA. Wi-Fi Calling, which is used to make and receive calls over the WiFi network, has been widely adopted and deployed to extend the coverage and increase the capacity in weak signal areas by moving traffic from LTE to Wi-Fi networks. In this paper, we analyze the security of Wi-Fi Calling specifications and discover several vulnerabilities that allow an adversary to track the location of users and perform DoS attacks.

Now I am researching for 4G/LTE vulnerabilities regrading privacy or integrity issues using sophisticated AI technologies.

Welcome any questions and comments whenever*^^*.
