Welcome to my GitHub profile! I’m a recent MSc graduate in Networked System Security from KTH Royal Institute of Technology, with experience in wireless security, Linux kernel development, and privacy-enhancing network protocols. I enjoy working at the intersection of systems, security, and real-world networking.
- Recent Role: Completed a visiting scholar researcher at KU Leuven (DistriNet), focusing on enterprise Wi-Fi security and protocol misconfigurations.
- Upcoming Paper: Co-authored a paper on certificate misconfigurations in WPA2/3 enterprise networks, accepted to CSNet 2025 (to appear soon).
- MSc Thesis: Developed and evaluated a MAC address re-randomization protocol inside the Linux
mac80211stack to defend against WiFi tracking. - Skill Set: Proficient in C, C++, and Python, with hands-on experience in network security protocols, Linux kernel development, and embedded systems.
- Interests: Wireless security, privacy protocols, and networked system optimization.
AP-Initiated Dynamic MAC Re-Randomization
- Developed a Dynamic MAC re-randomization protocol in the Linux kernel to address WiFi tracking risks.
- Integrated wmediumd and Mininet-WiFi to simulate real-world scenarios, achieving high privacy without compromising network performance.
- Conducted tests to analyze network impact, visualizing MAC transitions and linking accuracy.
- Support Repository: Check out for additional testing resources.
- Building Networked Systems Security: Designed a secure VPN-based network for remote data exchange, utilizing OpenVPN, OpenSSL, Docker, and RADIUS for secure access control.
- Facial Recognition Attendance System: Built an automated attendance system using OpenCV, face-recognition.
