Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: Wireless communication systems are very vulnerable to pilot contamination attacks, which represents a major physical layer security issue. Hence, it is necessary to apply different approaches and methods to the detection of this type of attack. One effective method proposed in the literature is 2-N-PSK pilot detection, which consists of training with two random N-PSK pilots. Although the method is broadly effective, it is not able to detect an attack initiated during the transmission of the second pilot of the pair in the case when both the legitimate and non-legitimate pilots coincide. In this paper, an improvement to this method is proposed to detect an intrusion which misses the first pilot transmission and initiates an attack during the second training period. This improved technique is based on channel gain comparison and eliminates the need to use threshold values in the detection – a drawback of previously-existing solutions.
