N2 - Modern railway systems rely on communication-based train control (CBTC) for traffic management and automation. CBTC provides the controller with precise, timely updates on the position/speed of trains and communicates the corresponding control information to the trains. However, disruptions due to potential component failures and jamming attacks threaten the communication availability in CBTC. To improve availability, we propose a countermeasure based on redundant communications. The proposed Transparent, Agnostic, Secure Communication (TASC) system sniffs and tunnels the CBTC messages through an alternative network to their intended receivers. Prior works mitigate the impact of jamming and failures through hardware modifications to CBTC. In contrast, TASC is transparent to the underlying system, causing no interference unless signaling is disrupted, and designed to be agnostic to communication protocols above the physical-layer. Unlike commonly adopted active redundancy via the duplication of components, TASC steps in only upon signaling disruptions, employing standby redundancy.
