Title: Comparison of Methods for the Detection of Pilot Contamination Attacks
Keywords: Pilot contamination attack, Channel estimation, Detection statistic, Key-confirmation.
Abstract: In the current paper, four different methods for the detection of pilot contamination attacks are examined and a comparison of their performance is provided. 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 is its large-scale fading dependence, which makes it vulnerable to attacks which imitate the natural channel improvement. Although the performance of the method based on secret key confirmation is not related to noise or fading, the technique significantly increases the computational complexity of the system.
