2.  Radio Frequency (RF) Fingerprinting  Research gaps  Objective  Experiment setup  Results  Conclusion 2

3.  Radio Frequency (RF) fingerprinting is the process of identifying a radio transmitter by the unique features present in its analog waveform. 3

4. 4 High End Receiver setup

5. 5 Channel Impairments Receiver Impairments

6.  Analog components at the receiver front-end also have impairments.  Channel impairments further distorts the unique RF features of the transmitter  How secure and robust RF fingerprinting is to impersonation attack? 6

12.  An attacker (malicious user) would be unaware of the impairments of a legitimate receiver. More importantly, the attacker would probably also be unaware of its own receiver impairments (which influence the fingerprint it creates for a target transmitter) and its transmitter impairments.  Therefore, the uncertainty associated with low end hardware increases the challenge for the attacker to create a signal that would deceive a legitimate user. 12
