SEMINARIO DI INFORMATICA
Martedì 6 Maggio 2014 alle ore 09:30 in aula 1BC50, Ivan Martinovic (University of Oxford) terrà un seminario dal titolo: "Fasten Your Seatbelts – Overview and Security Considerations of Next Generation Air Traffic Communication"
This lecture is about the security of the next generation air traffic surveillance technology based on Automatic Dependent Surveillance – Broadcast (ADS-B). The ADS-B protocol is already supported by the majority of international aircraft and will become mandatory in 2020 for most airspaces worldwide. While it is known that ADS-B might be susceptible to different impersonation and DoS attacks, the complexity and impact of launching these attacks has been debated controversially by the air traffic control community. Yet, the literature remains unclear on the requirements of launching ADS-B attacks in real-world environments, and on the constraints which affect their feasibility. In this lecture, we take a scientific approach to systematically evaluate realistic ADS-B attacks. Our objective is to shed light on the practicability of different threats and to quantify the main factors that impact the success of such attacks. Our results reveal some bad news: attacks on ADS-B can be inexpensive and highly successful. Using a controlled experimental design, we offer insights from a real-world feasibility analysis that leads to the conclusion that any safety-critical air traffic decision process should not rely exclusively on the ADS-B system.
