Abstract:

This work presents a detector for a pilot contamination attack (PCA) in multi-user time-division duplex (TDD) wireless networks. We consider a scenario in which an active eavesdropper with multiple antennas attempts a PCA to a Multiple-Input-Single-Output (MISO) target system. To fend off the PCA, we propose a PCA detector which exploits an imbalance between estimated channels in two-way training phases. Performance of the detector is analyzed in terms of detection probability. Numerical evaluations are also conducted for various combinations of system parameters to verify the analytic results.
