SPOOFING DETECTION DEVICE AND A SPOOFING DETECTION METHOD
A spoofing detection device is provided. The spoofing detection device includes an antenna configured to receive a signal from wireless communication; a processor configured to extract at least one feature of the received signal; a storage configured to store a local signal feature; a detection circuit configured to compare the extracted feature from the received signal and the local signal feature. The detection circuit is configured to decide if the signal is a spoofed signal based on a result of comparison between the extracted feature from the received signal and the local signal feature.
1 . A spoofing detection device, comprising:
an antenna configured to receive a signal from wireless communication;
a processor configured to extract at least one feature of the received signal;
a storage configured to store a local signal feature;
a detection circuit configured to compare the extracted feature from the received signal and the local signal feature,
wherein the detection circuit is configured to decide whether the signal is a spoofed signal based on a result of comparison between the extracted feature from the received signal and the local signal feature.
2 . The spoofing detection device according to claim 1 , wherein the spoofing detection device alarms when the received signal is decided as a spoofed signal.
3 . The spoofing detection device according to claim 1 , wherein the processor is configured to extract the at least one feature from a physical layer of the signal.
4 . The spoofing detection device according to claim 1 , wherein the signal includes in-phase (I) and in-quadrature (Q) components.
5 . The spoofing detection device according to claim 4 , wherein the extracted feature from the received signal includes at least one of amplitude information, frequency information, phase information, I-Q offset, quadrature skew and DC offset.
6 . The spoofing detection device according to claim 1 , wherein the spoofing detection device verifies the signal as reliable signal when the extracted feature from the received signal matches with the local signal feature.
7 . The spoofing detection device according to claim 1 , wherein the spoofing detection device is configured to be equipped on an aircraft.
8 . The spoofing detection device according to claim 1 , wherein the spoofing detection device is configured to be equipped on an unmanned aerial vehicle.
