Abstract
This talk will cover two recent air transportation-related thrusts of FORCES at MIT. The first thrust considers new approaches to characterizing the state and dynamics of networked systems using data. In doing so, we consider methods to cluster graphs based on network-theoretic properties such as nodal degrees and eigenvector centrality, and also properties of directed networks such as hub and authority scores. The problem of community detection, that is, grouping of nodes with strong connectivity, is also considered. We use the case study of air traffic delay networks to illustrate how these methods can be used to understand delay propagation and resilience of real-world networked systems. The second thrust deals with the problem of developing secure air traffic control systems. We develop a taxonomy of potential vulnerabilities in NextGen ATC systems, and identify attacks that could be addressed using existing technologies such as message authentication and confidentiality. We consider how problems such as the injection of false data and loss of availability (due to GPS jamming, for example) may be mitigated in onboard systems by checking for data consistency using models of aircraft dynamics. We also discuss the potential impacts of introducing unmanned systems into the airspace on the underlying threat models.
