I am Dr. Jaejong Baek (aka, JJ) , working for the SEFCOM lab and Center for Cybersecurity and Trusted Foundations (CTF) at Arizona State University as an Assistant Research Scientist. I received my Ph.D. from Yonsei University in South Korea. My research topics are mostly related to mobile and wireless network security issues like Telco (5G), Access Control, Blockchain, Digital Forensics, and Vehicle security.
Our paper "Targeted Privacy Attacks by Fingerprinting Mobile Apps in LTE Radio Layer" has been accepted in IEEE IFIP DSN 2023 (June 27-30, Porto, Portugal) This paper presents novel privacy attacks against LTE using machine learning to identify patterns in the communication between the UEs and eNBs without breaking into users' devices and the base station.
Our paper "SpaceMediator: Leveraging Authorization Policies to Prevent Spatial and Privacy Attacks in Mobile Augmented Reality" has been accepted in SACMAT 2023 (June 7-9, Trento, Italy). We present a new approach for managing access control policies in a mobile augmented reality (MAR) application based on policy-governed MAR apps against space invasion, space affectation attacks, and privacy leaks.

Our NSF proposal has been awarded on August 29, 2022: "CICI: UCSS: ScienceAccess: Enabling Zero-Trust Resource Access Management for Scientific Collaborations ", which will be collaborated with TAMU-CC. from Oct. 2022 to Sept. 2025. (Award # 2232911, $591,644)
Our extended edition of the Dypoldroid paper has been accepted to Information Systems Frontiers: "DyPolDroid: Protecting Against Permission-Abuse Attacks in Android" in August 2022. (Impact Factor: 5.261)
Our paper has been accepted to Applied Energy, titled "A Secure Distributed Ledger for Transactive Energy: The Electron Volt Exchange" in November 2020. (Impact Factor: 8.848)
Our team (Jaejong Baek, Sukwha Kyung, Gail-Joon Ahn) 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". (Patent issued)
Our 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. 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.
Welcome any questions and comments whenever*^^*.
