Crowdsourcing Security for Wireless Air Traffic Communications
Martin Strohmeier‚ Matthew Smith‚ Matthias Schäfer‚ Vincent Lenders and Ivan Martinovic
Protecting the security of the cyber-physical systems that make up the world’s critical infrastructures has been a recent hotly debated topic. Legacy wireless communication infrastructure is often an impediment to quickly improving these crucial systems, as cryptographic solutions prove impossible to deploy. In this article, we propose the establishment of a separate verification layer for sensitive wireless data powered by crowdsourced sensors connected to the Internet and apply it to the aviation domain. We first validate the need for independent data verification in air traffic control networks, where all wireless communication is conducted in the clear and thus subject to manipulation. To counter this threat, we develop a comprehensive model for the verification of wireless communication based on massively distributed data collection and outline how it can be used to immediately improve the security of unprotected air traffic control networks.
