卡车排队正在成为一种有前景的解决方案，并有许多经济激励措施。然而，让一辆新车安全地进入一个排是一项极其重要而艰巨的任务。现在还没有足够的方法来验证排内车辆的实际布置。具体地说，我们解决了排幽灵攻击的问题，在这种攻击中，攻击者假冒排内的存在以获得承认，并随后执行恶意攻击。为了解决这些问题，我们提出了一种新颖的自主排队准入方案Conway，它将车辆的数字证书绑定到它们的物理环境(即位置)。康沃伊利用这一发现，即车辆一起旅行经历了相似的背景，以证明随着时间的推移，它们是同时存在的。具体地说，它们经历了类似的道路(例如，颠簸和裂缝)和交通(例如，加速和转向)条件。我们的方法是基于车辆捕获该上下文的能力，生成指纹来建立共享密钥，然后将这些对称密钥绑定到它们的公钥。我们设计并实现了车队协议，并用真实的驾驶数据对其进行了评估。我们的实现表明，在相邻车道上行驶的车辆可以根据上下文充分区分，这可以用来阻止排幽灵攻击和类似的不当行为。
Truck platooning is emerging as a promising solution with many economic incentives. However, securely admitting a new vehicle into a platoon is an extremely important yet difficult task. There is no adequate method today for verifying physical arrangements of vehicles within a platoon formation. Specifically, we address the problem of a platoon ghost attack wherein an attacker spoofs presence within a platoon to gain admission and subsequently execute malicious attacks. To address such concerns, we present Convoy, a novel autonomous platoon admission scheme which binds the vehicles' digital certificates to their physical context (i.e., locality). Convoy exploits the findings that vehicles traveling together experience similar context to prove to each other over time that they are co-present. Specifically, they experience similar road (e.g., bumps and cracks) and traffic (e.g., acceleration and steering) conditions. Our approach is based on the ability for vehicles to capture this context, generate fingerprints to establish shared keys, and later bind these symmetric keys to their public keys. We design and implement the Convoy protocol and evaluate it with real-world driving data. Our implementation demonstrates that vehicles traveling in adjacent lanes can be sufficiently distinguished by their context and this can be utilized to thwart platoon ghost attacks and similar misbehavior.
