Abstract
This paper presents very promising radio frequency
(RF) fingerprinting techniques for the terminal-based detection of
fake base station (FBS) in a wireless cellular network. The
proposed schemes are based on identifying the analog hardware
impairments of the transmitter. In this regard, phase noise
analysis and its measured signatures reveal that low to medium
end software defined radio (SDR) acting as FBS can certainly be
detected if the detecting terminal’s own phase noise is at least 10-
dB better than the transmitter. However, for medium to high end
FBS, a computationally efficient network synchronized carrier
frequency offset (CFO) approach has been proposed and the
measurement results confirm that the regular base stations (RBS)
that are clock synchronized show identical CFO values whereas,
the FBS show large and random offset values. Furthermore, the
CFO stability (Frequency offset vs. time) signatures illustrate that
an FBS running by its own lazy clock show a large instability in
the frequency offset values and even in case of a precision clock, fluctuations vanish though the stabilized offset is still large enough
for a user terminal to distinguish the FBS from the RBS.
