Title: Detecting pilot contamination attacks in wireless cyber-physical systems Keywords: Pilot contamination attack, Cyber-Physical Systems, Wireless Abstract: In this chapter, four different methods for the detection of pilot contamination attacks are examined and their performance is compared. The main problem with the scheme with two pilots, its low detection probability, is solved when more pilots are used, but at the cost of reduced robustness against noise. The biggest disadvantage of the method, which analyses the energy of the received signal, lies in its large-scale fading dependence, which makes it vulnerable to attacks that imitate the natural channel improvement. Although the performance of the method based on secret key confirmation is not related to noise or fading, this technique significantly increases the computational complexity of the system. Two recently developed approaches to improving the performance of the scheme with two pilots are also discussed: the first operating with channel gain and the second with shifted constellations.
