Abstract:
Security Protocols for Operating Trains
I
will describe security protocols designed to use on railroad tracks. Communication-based
Train Operation provides signaling, authority and track status for operating
passenger and cargo trains. Shinkansen in Japan, TGV in France and other modern
trains obtain signals and track information using wireless network protocols
such as GSM-R and LTE. Rail Safety Improvement Act of 2008 mandates American
Railroads to operate their trains using wireless protocols by 2015, commonly
referred to as Positive Train Control (PTC). I will describe my research team’s
on-going work in securing the wayside interface device network of the planned
PTC system.
