Set Up

Development of high-speed railways set up challenges for new communication technologies. With the increase in speed, new requirements for communication systems have emerged that HSR requires greater reliability, capacity and shorter response time for efficient and safe operations. Mobile communication systems are crucial for the competitiveness of the railway industry and therefore have become one of the priorities addressed by the participants in the railway system to take advantage of technological opportunities to improve operational processes and the quality of provided transport services. The European Rail Traffic Management System (ERTMS) uses the Global System for Mobile Communications for Railways (GSM-R) for voice and data communication to communicate between trains and control centers. The International Railway Union is exploring new ways of communicating for high-speed railways because as speed increases this system becomes unreliable in information transmission. This paperwork presents an analysis of the evolution of communications on European railways since the usage of GSM-R. In addition, an overview of the various alternative solutions proposed during the time (LTE-R, Future Railway Mobile Communication System) as possible successors to GSM-R technology is given.

Railway systems have evolved considerably in the last years with the adoption of new communication technologies. Aiming to achieve a single European railway network, the European Rail Traffic Management System (ERTMS) emerged in Europe to substitute multiple and noninteroperable national railway communication systems. This system and its security strategies were designed in late 1990s. Recent works have identified vulnerabilities related to integrity, authenticity, availability, and confidentiality. In the context of defining effective countermeasures to mitigate potential vulnerabilities, these vulnerabilities have to be analysed. In this article we introduce a framework that attempts to challenge ERTMS security by evaluating the exploitability of these vulnerabilities.

The Impact

<div> <div> <div> <p>Communication Based Train Control (CBTC) and the European Rail Traffic Management Systems (ERTMS) are prevailing radio controlled systems for railway. As a part of the ERTMS standard, the European Train Control System (ETCS) implements on-board control systems throughout multiple radios. CBTC makes use of RF-based data communication systems (DCSs) for train control and traffic management. Even if ERTMS and CBTC have different origins, both make use of wireless communications for safety related systems. This paper describes cybersecurity considerations for CBTC. First, authors studied the impact of security on intra-vehicular communications in a real tunnel scenario, e.g. for urban transit where the usage of security is mandatory in order to maintain the system safety. Secondly, the impact of a jamming attack against ETCS radio has been analyzed. Measurement campaigns confirmed Host Identity Protocol (HIP) as an effective security solution at layer 3 in terms of the protocol overhead introduced. On the other hand, the Balise Transmission Module (BTM), included in ETCS standard, is sensitive to jamming attack and the measurements presented here would offer the sights for further security considerations around the CBTC. </p> </div> </div> </div>

And Control

Successful operation of the railways as a large technological system is directly related to the reliable and timely transmission of data and information. Therefore, the role of the information and communication system (ICS) has irreplaceable importance for operation and functioning of the railways. Considering that the railway modernization represents an uninterrupted process, it is necessary to ensure constant technical and technological development and application of the latest achievements in the field of information and communication systems. The railway ICS, among other things, provides infrastructure for the automatic control systems, traffic management and control, monitoring and navigation systems, data processing devices, and it also provides support to other subsystems designed for safe and consistent use of the line, as well as efficient management of the modern rail transportation system.

The Future

In the future air traffic management (ATM) system, flight crews will most likely have the option to dynamically adjust their flight path without prior approval from the ground. As a result, knowledge of intent may no longer be shared by pilots and controllers, and the potential for unforeseen conflicts as well as the need for immediate yet coordinated interventions can be expected to increase. To support such a short-term reactive approach to traffic management and separation, highly effective means of communication will be required that allow for a rapid creation and update of shared frames of reference. It is not clear that recently developed and envisioned communication media and technologies are designed with these goals in mind. A recent line of research explored the ability of two communication systems - DataLink and the Voice Control and Switching System (VSCS)—to handle communication not only in the current air traffic control system but to also support the highly flexible operations and new coordination and knowledge demands that are likely going to be part of the future ATM system. System reviews, conceptual simulations, and a pilot survey served to gather information on current and potential future experiences with these systems. The results of our research suggest that neither system is tailored to future ATM operations, and that they create new challenges even in the context of the current system.
