论文摘要
智能车辆中连接技术的无处不在以及其功能的增量自动化有望取得显着好处，包括交通拥堵和道路死亡的大幅下降。但是，增加自动化和连接性扩大了攻击表面，并增强了恶意实体成功执行攻击的可能性。在本文中，我们提出了一个基于区块链的框架，以确保智能车辆（B-Ferl）。 B-Ferl使用权限的区块链技术来量身定制信息访问连接的车辆生态系统中的受限实体。它还使用车辆和路边单元之间的挑战响应数据交换来监视车辆的内部状态，以识别车辆网络妥协的案件。为了在车辆网络中启用真实且有效的通信，只有区块链中具有可验证记录的车辆可以交换消息。通过定性论点，我们表明B-Ferl对已确定的攻击具有弹性。同样，在模拟场景中进行定量评估表明，B-Ferl确保了合适的响应时间和所需的储存尺寸与现实情况兼容。最后，我们演示了B-Ferl如何实现与汽车生态系统（例如信任管理，车辆取证和安全车辆网络）相关的各种重要功能。
The ubiquity of connecting technologies in smart vehicles and the incremental automation of its functionalities promise significant benefits, including a significant decline in congestion and road fatalities. However, increasing automation and connectedness broadens the attack surface and heightens the likelihood of a malicious entity successfully executing an attack. In this paper, we propose a Blockchain based Framework for sEcuring smaRt vehicLes (B-FERL). B-FERL uses permissioned blockchain technology to tailor information access to restricted entities in the connected vehicle ecosystem. It also uses a challenge-response data exchange between the vehicles and roadside units to monitor the internal state of the vehicle to identify cases of in-vehicle network compromise. In order to enable authentic and valid communication in the vehicular network, only vehicles with a verifiable record in the blockchain can exchange messages. Through qualitative arguments, we show that B-FERL is resilient to identified attacks. Also, quantitative evaluations in an emulated scenario show that B-FERL ensures a suitable response time and required storage size compatible with realistic scenarios. Finally, we demonstrate how B-FERL achieves various important functions relevant to the automotive ecosystem such as trust management, vehicular forensics and secure vehicular networks.
