摘　　要：随着无线通信技术的迅速发展,无线网络规模急剧增大,当前无线网络的安全威胁形势日益严峻。面向最为常见的无线网络窃听攻击,深入探讨了这类安全威胁的现状和相关检测技术的研究进展,具体分析了主动窃听攻击与被动窃听攻击的两大类窃听检测方法的技术原理及优缺点。同时针对基于本振泄露的被动无线窃听装置检测方法提出了一种软件无线电实现方案,测试了该系统在不同条件下对无线窃听装置的检测性能,验证了WiFi无线网络中隐藏式被动窃听装置的检测能力。With the rapid development of wireless communication technology,the scale of wireless networks is increasingdramatically,while the security attacks against wireless networks become more frequent and difficult to counter.This paper investigates the development status of wireless eavesdropping technology faced by wireless networks.The paper analyzes the operation principles,pros,and cons of the eavesdropping detection methods against active and passive eavesdropping attacks.Meanwhile,a software-defined radio(SDR)implementation of wireless passive eavesdroppers detection approach based on local oscillator leakage is proposed.The detection performance under different conditions is presented,and it demonstrates the validity of detecting hidden passive eavesdropping devices in WiFi networks.
