Cross-Layer Defense Methods for Jamming-Resistant CBTC Systems
IEEE Transactions on Intelligent Transportation Systems, 2021Communication-based Train Control (CBTC) systems are the burgeoning directions for developing future train control systems. With the adoption of wireless communication and network techniques, train control systems are more vulnerable to cyber-attacks. Notably, the jamming attacks, aiming at the handoff process that is the weakest part of train ground ...

Modeling the CBTC Railway System of Siemens with ScOLa
International Journal of Intelligent Transportation Systems Research, 2017Considering their increasing complexity, industrial systems are, in general, specified in a natural language. In railway systems, the design phase results an ambiguous and laborious system specification. The objective of this paper is to present ScOLa, a formal modeling language based on scenarios and built for railway system specifications.

A Game Framework to Secure Control of CBTC Systems
2020To meet the growing railway-transportation demand, researchers have designed a new train control system, communication-based train control (CBTC) system, to maximize the ability of train lines by reducing the headway of each train. However, wireless communications expose the CBTC system to new security threats.
