Jaejong Baek

Welcome, ^^

I am Dr. Jaejong Baek (alias: jj) , working for Center for Cybersecurity and Digital Forensics(CDF) at GSI at KED at Arizona State University as an Assistant Research Scientist. I received Ph.D. and M.S. from Yonsei University JYP and Bong Joon-ho graduated. I had worked for the ROK Navy as a cybersecurity officer for 20 years. My research topic focuses on the mobile and wireless network security system like Cellular (4G/5G), SDN ,Blockchain, and digital forensics.

Our paper has been accepted to HICSS-54 (Jan. 4, 2021), titled as "MuTent: Dynamic Android Intent Protection with Ownership-Based Key Distribution and Security Contracts".

Our team (Jaejong Baek Ph.D. & Sukwha Kyung led by Gail-Joon Ahn Ph.D) was recognized as the Most Innovative Capability in the Blockchain Innovation Challenge hosted by ASURE. The title of the project is "Cryptographic Key Management System using a Distributed Shared Ledger". (Pending patent, 62/912,985 Oct. 10, 2019 )

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/5G/SDN vulnerabilities regrading privacy or integrity issues and Blockchain technology in physical system like an energy power system.

Welcome any questions and comments whenever*^^*.
