Title: An improved technique for the detection of pilot contamination attacks in TDD wireless communication systems
Keywords: Physical layer security, Pilot contamination attacks, Wireless communications
Abstract: One of the problems phasing the physical layer security of a wireless system is its vulnerability to pilot contamination attacks and hence schemes for its detection need to be applied. A method proposed in the literature consists of training with two N-PSK pilots. Although the method is effective in most of the cases, it is not able to discover an attack initiated during the transmission of the second pilot from the pair if both the legitimate and non-legitimate pilots coincide. In this current paper, an improvement to this method is proposed which detects an intruder who misses the first pilot transmission. The suggested improvement eliminates the usage of threshold values in the detection-A main drawback of previously existing solution.
