针对智能网联汽车现有入侵响应依赖安全运营中心、耗时且扩展性不足的问题,提出车载动态入侵响应系统REACT,含响应列表、评估与选择方法,经嵌入式平台与两个攻击用例验证,具备响应快、占存小、可动态调参等优势。

摘要:

自动驾驶与网联汽车正快速发展,集成了大量技术与软件。然而这一进展也使其成为网络安全攻击的理想目标。随着技术进步,网络威胁风险不断攀升,研究重点正从单纯防御攻击转向同时降低攻击影响。当前解决方案依赖车辆安全运营中心,先分析攻击信息再制定响应策略。但该过程耗时较长,面临可扩展性挑战,还存在车辆互联带来的其他问题。本文提出一种集成在车辆内部的动态入侵响应系统,使车辆能几乎即时响应各类事件,从而减少与车辆安全运营中心交互的需求。该系统提供了全面的潜在响应列表、响应评估方法以及多种响应选择机制。所提方案在嵌入式平台上实现,以两个不同的网络攻击用例作为系统评估基础。评估结果凸显了该系统的适应性、快速响应能力、极小的内存占用,以及动态调整系统参数的能力。该方案证明了在智能汽车中引入动态响应机制的必要性与可行性,这是保障未来智能出行安全性与韧性的关键因素。

英文摘要:

Autonomous and connected vehicles are rapidly evolving, integrating numerous technologies and software. This progress, however, has made them appealing targets for cybersecurity attacks. As the risk of cyber threats escalates with this advancement, the focus is shifting from solely preventing these attacks to also mitigating their impact. Current solutions rely on vehicle security operation centers, where attack information is analyzed before deciding on a response strategy. However, this process can be time-consuming and faces scalability challenges, along with other issues stemming from vehicle connectivity. This paper proposes a dynamic intrusion response system integrated within the vehicle. This system enables the vehicle to respond to a variety of incidents almost instantly, thereby reducing the need for interaction with the vehicle security operation center. The system offers a comprehensive list of potential responses, a methodology for response evaluation, and various response selection methods. The proposed solution was implemented on an embedded platform. Two distinct cyberattack use cases served as the basis for evaluating the system. The evaluation highlights the system's adaptability, its ability to respond swiftly, its minimal memory footprint, and its capacity for dynamic system parameter adjustments. The proposed solution underscores the necessity and feasibility of incorporating dynamic response mechanisms in smart vehicles. This is a crucial factor in ensuring the safety and resilience of future smart mobility.
