RF Fingerprinting


Radio frequency (RF) signals generated by different transmitters are known to possess certain salient characteristics. These characteristics are due to the transient response of the transmitter following its turn-on. Therefore, essentially the behavior in the transient can be exploited so as to identify the signal's original source by creating a profile of the transmitter. Our ongoing research investigates the potential for extending RF fingerprinting methodology to go beyond transient response and deploying it for network-security purposes. This capability brings a new level of functionality to wireless networks with stringent security requirements. The results of this study will be used to develop new forensics techniques and to enable alternate mechanisms for access control and authentication as well as mitigating the threat of attacks in the wireless medium.
