由于无线介质的开放性，无线通信特别容易受到窃听攻击。本文设计了一种新的无线通信系统来应对窃听攻击。所提出的系统可以使合法接收者获得所需的消息，同时通过机密性和欺骗的结合，窃听者能够听到“假”但有意义的消息，从而迷惑窃听者并实现额外的隐藏，进一步保护交换的消息。为了实现这一目标，我们提出了利用发送器和接收器之间的无线信道特性来隐藏交换消息的技术，以及吸引窃听者逐渐接近陷阱区域的技术，在陷阱区域中窃听者可以获得虚假消息。我们还对发射器和接收器之间建立的安全通道进行理论和实证分析。我们使用通用软件定义无线电外围设备 (USRP) 开发原型系统。实验结果表明，处于陷阱位置的窃听者可以接收到误码率（BER）接近于0的虚假信息，并且具有多个天线的发射机可以成功部署陷阱区域。
Due to the open nature of the wireless medium, wireless communications are especially vulnerable to eavesdropping attacks. This article designs a new wireless communication system to deal with eavesdropping attacks. The proposed system can enable a legitimate receiver to get desired messages and meanwhile an eavesdropper to hear “fake” but meaningful messages by combining confidentiality and deception, thereby confusing the eavesdropper and achieving additional concealment that further protects exchanged messages. Towards this goal, we propose techniques that can conceal exchanged messages by utilizing wireless channel characteristics between the transmitter and the receiver, as well as techniques that can attract an eavesdropper to gradually approach a trap region, where the eavesdropper can get fake messages. We also provide both theoretical and empirical analysis of the established secure channel between the transmitter and the receiver. We develop a prototype system using Universal Software Defined Radio Peripherals (USRPs). Experimental results show that an eavesdropper at a trap location can receive fake information with a bit error rate (BER) close to 0, and the transmitter with multiple antennas can successfully deploy a trap area.
