Unauthorized Bluetooth devices or rogue devices can im personate legitimate devices through address and link key spoofing. Moreover, they can infiltrate a Bluetooth net work and initiate other forms of attacks. This paper inves tigates a novel intrusion detection approach, which makes use of radio frequency fingerprinting (RFF) for profiling, Hotelling’s T2 statistics for classification and a decision fil ter, for detecting these devices. RFF is a technique that is used to uniquely identify a transceiver based on the tran sient portion of the signal it generates. Moreover, the use of a statistical classifier proves advantageous in minimiz ing requirements for memory. Finally, the detection rate is also improved by incorporating a decision filter, which takes the classification results of a set of events into con sideration, prior to rendering the final decision. The aver age False Alarm Rate of five percent and Detection Rate of ninety-three percent support the feasibility of employing these components to address the aforementioned problem.
