物联网（IoT）设备共享着射频频段（例如2.4GHz工业、科学和医疗（ISM）频段）。物联网设备数量呈指数级增长，这给物联网网络中的网关带来了潜在的安全问题。在本文中，我们介绍了一组通过隐蔽干扰实施的新型攻击——攻击者伪装成（或攻陷）合法的WiFi设备，然后发送WiFi数据包，以阻止ZigBee设备通信，或与ZigBee数据包发生冲突。通过这种方式，隐蔽干扰有可能严重延迟ZigBee数据包的接收，而这些数据包可能包含重要信息（例如来自可穿戴设备的关键健康数据、火灾警报和入侵警报）。为抵御这些攻击，我们设计了一种新颖的ZigBee数据提取技术，该技术能够从与WiFi数据包发生冲突的ZigBee数据包中恢复ZigBee数据。我们在不同的实际场景中对设计进行了广泛评估。结果表明，（采用我们所提方法保护的）ZigBee设备的性能与未遭受隐蔽干扰攻击的设备相近。此外，与未受保护的设备相比，在遭受隐蔽干扰攻击时，受保护设备的吞吐量比未受保护设备高出15倍以上。
Internet-of-things (IoT) devices are sharing the radio frequency band (e.g., 2.4 GHz ISM band). The exponentially increasing number of IoT devices introduces potential security issues at the gateway in IoT networks. In this paper, we introduce a set of new attacks through concealed jamming - an adversary pretends to be (or compromises) a legitimate WiFi device, then sends out WiFi packets to prevent ZigBee devices' communication or collide with ZigBee's packets. By doing this, concealed jamming has the potential to severely delay the reception of ZigBee packets that may contain important information (e.g., critical health data from wearables, fire alarms, and intrusion alarms). To defend against these attacks, we designed a novel ZigBee data extraction technique that can recover ZigBee data from the ZigBee packets that were collided with WiFi packets. We extensively evaluated our design in different real-world settings. The results show that ZigBee devices (protected by our proposed methods) achieve similar performance as those that are not under the concealed jamming attack. Moreover, compared with unprotected devices, their throughput is more than 15 times higher than the unprotected one that is under concealed jamming attacks.
