<strong>The</strong> RIKEN BNL Research Center (RBRC) was established in April 1997 at Brookhaven National Laboratory. It is funded<br />
by the ‘Rikagaku Kenkyusho’ (RIKEN, <strong>The</strong> Institute of Physical <strong>and</strong> Chemical Research) of Japan. <strong>The</strong> Memor<strong>and</strong>um of<br />
Underst<strong>and</strong>ing between RIKEN <strong>and</strong> BNL, initiated in 1997, has been renewed in 2002 <strong>and</strong> again in 2007. <strong>The</strong> Center is<br />
dedicated to the study of strong interactions, including spin physics, lattice QCD, <strong>and</strong> RHIC physics through the nurturing of<br />
a new generation of young physicists. <strong>The</strong> RBRC has both a theory <strong>and</strong> experimental component. <strong>The</strong> RBRC <strong>The</strong>ory Group<br />
<strong>and</strong> the RBRC Experimental Group consists of a total of 25-30 researchers.<br />

Spectral Domain RF Fingerprinting for 802.11 Wireless Devices<br />

<strong>The</strong> increase in availability <strong>and</strong> reduction in cost of commercial communication devices (IEEE compliant such as 802.11,<br />
802.16, etc) has increased wireless user exposure <strong>and</strong> the need for techniques to properly identify/classify signals for increased<br />
security measures. A communication device’s emission includes intentional modulation that enables correct device operation.<br />
Hardware <strong>and</strong> environmental factors alter the ideal response <strong>and</strong> induce unintentional modulation effects. If these effects<br />
(features) are sufficiently unique it becomes possible to identify a device using its fingerprint, with potential discrimination<br />
of not only manufacturers but possibly serial numbers for a given manufacturer. Previous AFIT research has demonstrated<br />
effectiveness at RF Fingerprinting using 802.11A signals with 1) spectral correlation on Power Spectral Density (PSD)<br />
Fingerprints, 2) Multiple Discriminant Analysis/Maximum Likelihood (MDA/ML) classification with fingerprints obtained<br />
from Time Domain (TD) <strong>and</strong> Wavelet Domain (WD) statistical features. As used here, Spectral Domain (SD) fingerprinting<br />
uses the Fourier Transform to calculate PSD features for device discrimination. Results here show some improvement over<br />
the WD approach (gain approximately equal 3 dB) <strong>and</strong> significant improvement over the TD approach (gain approximately<br />
equal 8 dB gain).<br />
