摘　　要：利用开机瞬态特征对蓝牙传输设备进行射频指纹识别时,开机瞬态信号的捕获与提取存在一定的局限性。为此,提出将频率跳变瞬态特征用于蓝牙设备的唯一性鉴别,以克服开机瞬态特征的局限性。在射频指纹识别中的数据获取、瞬态信号检测、指纹提取和分类过程中对该特征进行验证,根据实验数据对鉴别性能进行评估。分析结果表明,利用频率跳变瞬态特征能够成功鉴别蓝牙设备。以对虫洞攻击的检测和防御为例,进一步分析射频指纹识别在蓝牙网络安全协议中的应用,并给出基于蓝牙指纹识别的安全链路管理协议。It is limitary to classify the radio devices by utilizing the turn-on transients character, when the turn-on transient signals are captured and extracted. Aiming at this problem, this paper investigates Frequency Hopping（FH） transients character which can be used to classify the bluetooth devices alike the Turn-on Transients（TOT） character but get rid of the limitation which the RFF based TOT character has. The FHT-Character based on the Radio Frequency Fingerprinting（RFF） process is validated, which includes data acquisition, transient detection, radio frequency fingerprint extraction, and classification subsystems. A classification performance of the identification system is evaluated from experimental data. It is demonstrated that the FHT character can be used to classify the bluetooth devices successfully. It further analyzes the implications of device fingerprinting on the security of bluetooth networking protocols which is illustrated by the example of the detection and combat for wormhole attacks. From this, a safe link management protocol is given which is based on bluetooth fingerprinting.
