Cross-Technology Communication(CTC) enables that WiFi devices can talk to ZigBee devices directly without any hardware changes or gateway equipment, and WiFi occupies a much wider bandwidth (20MHz) than ZigBee (2MHz), which sheds the light on spoofing-jamming attack based on CTC, where a WiFi device, as a sophisticated attacker spoofs or jams an area in which multiple-channels sensor network operating. In this work, we attempt to emulate two ZigBee frames under different frequencies within a single WiFi frame by controlling non-continuous bands of subcarriers. In other words, a WiFi device can independently communicate with the ZigBee devices operating in two channels. In a different perspective, the application based on CTC will be significantly impaired when CTC suffers from malicious attacks such as spoofing or jamming. In our work, we implement a parallel spoofing system, called SamBee, that can spoof the ZigBee devices operating in two different channels or jam the ZigBee devices operating in five distinct channels simultaneously only using a single WiFi frame, which causes maximum damage to the network in term of corrupted communication links with low cost. We implement our design based on a USRP-N210 and MICAz hybrid platform, the results show that parallel spoofing attacks and multiple-channels jamming attacks based on CTC is feasible, and our results also provide valuable insights about the associated defense mechanisms on achieving desirable performance.

跨技术通信（CTC）使 WiFi 设备可以直接与 ZigBee 设备通信，无需任何硬件更改或网关设备，并且 WiFi 占用的带宽（20MHz）比 ZigBee（2MHz）宽得多，这为欺骗干扰攻击提供了线索基于 CTC，其中 WiFi 设备作为复杂的攻击者欺骗或干扰多通道传感器网络运行的区域。在这项工作中，我们尝试通过控制子载波的非连续频带来模拟单个 WiFi 帧内不同频率下的两个 ZigBee 帧。换句话说，一个 WiFi 设备可以独立地与运行在两个信道中的 ZigBee 设备通信。换个角度看，基于CTC的应用在CTC遭受欺骗、干扰等恶意攻击时，会受到明显的损害。在我们的工作中，我们实现了一个名为 SamBee 的并行欺骗系统，它可以欺骗在两个不同信道中运行的 ZigBee 设备或仅使用单个 WiFi 帧同时干扰在五个不同信道中运行的 ZigBee 设备，这对网络造成最大损害低成本的通信链路。我们基于 USRP-N210 和 MICAz 混合平台实现了我们的设计，结果表明基于 CTC 的并行欺骗攻击和多通道干扰攻击是可行的，我们的结果还提供了有关实现理想性能的相关防御机制的宝贵见解. 它可以欺骗在两个不同通道中运行的 ZigBee 设备，或者仅使用单个 WiFi 帧就同时干扰在五个不同通道中运行的 ZigBee 设备，从而以低成本破坏通信链路对网络造成最大损害。我们基于 USRP-N210 和 MICAz 混合平台实现了我们的设计，结果表明基于 CTC 的并行欺骗攻击和多通道干扰攻击是可行的，我们的结果还提供了有关实现理想性能的相关防御机制的宝贵见解. 它可以欺骗在两个不同通道中运行的 ZigBee 设备，或者仅使用单个 WiFi 帧就同时干扰在五个不同通道中运行的 ZigBee 设备，从而以低成本破坏通信链路对网络造成最大损害。我们基于 USRP-N210 和 MICAz 混合平台实现了我们的设计，结果表明基于 CTC 的并行欺骗攻击和多通道干扰攻击是可行的，我们的结果还提供了有关实现理想性能的相关防御机制的宝贵见解.
