ESWORD：无线干扰攻击在真实仿真网络中的实现
ESWORD: Implementation of Wireless Jamming Attacks in a Real-World Emulated Network
摘要：
无线干扰攻击一直困扰着无线通信系统，并且随着技术进步将继续如此。这些攻击属于电子战（EW）的范畴，这是电磁频谱攻击和防御中不断增长的领域，其中一个子类别是电子攻击。干扰攻击属于电子战的这一特定子类别，因为它们包括试图干扰、拒绝、降级、破坏或欺骗电磁频谱中的合法信号的对抗性信号。虽然干扰不会消失，但最近的研究进展已经开始通过利用新的方法和技术（如机器学习）来对抗这些攻击。然而，由于对频谱发射的严格规定，在广泛和现实的规模上测试这种干扰解决方案是一项艰巨的任务。在本文中，我们介绍了eSWORD，第一个大规模的框架，允许用户安全地进行实时和控制干扰实验的硬件在环。这是通过将eSWORD集成到Colosseum无线网络仿真器中来实现的，该仿真器可以使用多达50个软件定义的无线电节点进行大规模实验。我们通过空中无线测试平台（确保在进行实验时采取了安全措施）比较了eSWORD与真实干扰系统的性能。我们的实验结果表明，eSWORD遵循类似的模式，在吞吐量，信噪比和链路状态，以现实世界的干扰实验，证明了高精度的仿真eSWORD设置。
英文摘要：
Wireless jamming attacks have plagued wireless communication systems and will continue to do so going forward with technological advances. These attacks fall under the category of Electronic Warfare (EW), a continuously growing area in both attack and defense of the electromagnetic spectrum, with one subcategory being electronic attacks. Jamming attacks fall under this specific subcategory of EW as they comprise adversarial signals that attempt to disrupt, deny, degrade, destroy, or deceive legitimate signals in the electromagnetic spectrum. While jamming is not going away, recent research advances have started to get the upper hand against these attacks by leveraging new methods and techniques, such as machine learning. However, testing such jamming solutions on a wide and realistic scale is a daunting task due to strict regulations on spectrum emissions. In this paper, we introduce eSWORD, the first large-scale framework that allows users to safely conduct real-time and controlled jamming experiments with hardware-in-the-loop. This is done by integrating eSWORD into the Colosseum wireless network emulator that enables large-scale experiments with up to 50 software-defined radio nodes. We compare the performance of eSWORD with that of real-world jamming systems by using an over-the-air wireless testbed (ensuring safe measures were taken when conducting experiments). Our experimental results demonstrate that eSWORD follows similar patterns in throughput, signal-to-noise ratio, and link status to real-world jamming experiments, testifying to the high accuracy of the emulated eSWORD setup.
