摘　　要：已有的射频指纹技术缺乏理论支撑,无法摆脱对设备身份识别过程中借助信道特征的依赖。该文针对直接序列扩频的ZigBee信号,提出了一种基于扩频还原的射频指纹提取方法。在60台ZigBee设备上以及4种不同的实验场景中进行试验,设备分类准确率最高可达99.8%。该方法的鲁棒性更强、计算量更小,具有较强的实用性。The existing radio frequency fingerprinting technique lacks theoretical support and cannot get rid of the suspicion of identifying the process of device identification with the help of channel features.In this paper,a radio frequency fingerprint extraction method based on spread spectrum reduction is proposed for ZigBee signals with direct sequence spread spectrum.The method achieves device classification accuracy up to 99.8%on 60 ZigBee devices and in four different experimental scenarios.The method is more robust and less computationally intensive,making it highly practical.
