Applying channel information for user authentication is gaining attention in the area of wireless network security. Numerous studies have demonstrated reconfigurable antennas with multiple operating modes that have the ability to choose the best channel in a given environment. We investigate the performance gains that can be achieved by using multiple uncorrelated channel realizations for user authentication at the physical layer by employing a reconfigurable antenna. Ray tracing simulations using a reconfigurable circular patch antenna were carried out and the intruder detection rate and false alarm rates were studied as a function of the number of available antenna modes and the SNR at the receiver.
