Systematic Security Analysis of Cellular Network Specifications and Implementations
Overview On April 11, 2025, we were honored to host Dr. Imtiaz Karim, a Postdoctoral Researcher at Purdue University and incoming Assistant Professor at the University of Texas at Dallas, for a distinguished research talk titled “Systematic Security Analysis of Cellular Network Specifications and Implementations.” Dr. Karim presented a compelling overview of the security challenges in modern cellular networks, particularly 4G and 5G, and introduced CellularLint, a cutting-edge tool that uses large language models to identify inconsistencies in cellular specifications. He further discussed his methodologies for analyzing protocol implementations and revealed a range of vulnerabilities that have influenced updates to industry standards. The talk concluded with Dr. Karim’s vision for securing future wireless communication systems, including 6G. We sincerely thank Dr. Karim for sharing his impactful research and insights with our department.
