摘要:

现代火车依靠位于轨道上的应答器(通信信标)在它们穿越铁路网络时提供位置信息。符合欧洲应答器标准的应答器在设计时没有考虑到安全性,因此容易受到针对数据可用性、完整性或真实性的网络攻击。在这项工作中,我们讨论了数据完整性威胁的应答器传输模块,并使用高保真仿真研究数据完整性攻击所带来的风险。为了减轻这种风险,我们提出了一个实用的两层解决方案:在设备级,我们设计了一个轻量级的和低成本的加密解决方案,以保护位置信息的完整性;在系统层,我们设计了一个安全的混合训练速度控制器,以减轻各种攻击下的影响。我们的仿真结果证明了我们提出的解决方案的有效性。

英文摘要:

Modern trains rely on balises (communication beacons) located on the track to provide location information as they traverse a rail network. Balises, such as those conforming to the Eurobalise standard, were not designed with security in mind and are thus vulnerable to cyber attacks targeting data availability, integrity, or authenticity. In this work, we discuss data integrity threats to balise transmission modules and use high-fidelity simulation to study the risks posed by data integrity attacks. To mitigate such risk, we propose a practical two-layer solution: at the device level, we design a lightweight and low-cost cryptographic solution to protect the integrity of the location information; at the system layer, we devise a secure hybrid train speed controller to mitigate the impact under various attacks. Our simulation results demonstrate the effectiveness of our proposed solutions.
