论文摘要
在地面上部署的自动依赖监视广播（ADS-B）传感器对于观察飞机的空中移动至关重要。然而，它们的非系统性放置导致某些领域的传感器覆盖范围过高，并且在其他领域的传感器覆盖率不足。迄今为止，ADS-B传感器覆盖范围已被认可并被分析为可用性问题。它是通过传感器放置优化技术来解决的，旨在覆盖足够大的区域。在本文中，我们证明了ADS-B传感器的非系统放置导致安全问题，因为保护机制的实现和可能部署与ADS-B传感器覆盖范围的冗余方面紧密相关。特别是，我们将ADS-B传感器覆盖范围建模为多维安全问题。然后，我们使用多目标优化技术来解决此问题并得出安全性优化的近乎最佳位置解决方案。我们的结果表明，传感器的位置如何通过在特定地理区域内提供足够数量的传感器来验证位置索赔并减少暴露于干扰攻击的情况下，如何在降低攻击者的成功率中发挥重要作用。
Automatic Dependent Surveillance Broadcast (ADS-B) sensors deployed on the ground are central to observing aerial movements of aircraft. Their unsystematic placement, however, results in over-densification of sensor coverage in some areas and insufficient sensor coverage in other areas. ADS-B sensor coverage has so far been recognized and analyzed as an availability problem; it was tackled by sensor placement optimization techniques that aim for covering large enough areas. In this paper, we demonstrate that the unsystematic placement of ADS-B sensors leads to a security problem, since the realization and possible deployment of protective mechanisms is closely linked to aspects of redundancy in ADS-B sensor coverage. In particular, we model ADS-B sensor coverage as a multi-dimensional security problem. We then use multi-objective optimization techniques to tackle this problem and derive security-optimized near-optimal placement solutions. Our results show how the location of sensors play a significant role in reducing the success rate of attackers by providing a sufficient number of sensors within a specific geographical area to verify location claims and reducing the exposure to jamming attacks.
