REGISTER FOR THE NEXT AOC WEBINAR: Enhancing Network Security, December 11
Thursday, December 11 | 1400-1500 EST (1900-2000 GMT)
Wireless Access Points (WAP) remain one of the top 10 network security threats. Research has focused on developing a physical (PHY) layer aware Radio Frequency (RF) air monitoring system with multi-factor authentication to provide a first-line of defense for network security – stopping attackers before they can gain access to critical infrastructure networks through vulnerable WAPs. This webinar will present early results on the identification of OFDM-based 802.11a WiFi devices using RF Distinct Native Attribute (RF-DNA) fingerprints produced by the Fractional Fourier Transform (FRFT). These fingerprints are input to a "Learning from Signals" (LFS) classifier which uses hybrid Differential Evolution/Conjugate Gradient (DECG) optimization to determine the optimal features for a low-rank model to be used for authentication. Results are presented for devices under the most challenging conditions of intra-manufacturer classification, i.e., same-manufacturer, same-model, differing only in serial number. The results of Fractional Fourier Domain (FRFD) RF-DNA fingerprints demonstrate significant improvement over results based on Time Domain (TD), Spectral Domain (SD) and even Wavelet Domain (WD) fingerprints.
