“…This case corresponds to the deep fading and these measurements should be discarded before quantization. A similar AR model is used to establish the relation between adjacent probing, and the hypothesis testing is implemented to perform the authentication of the access node in a fixed position [16] . The proposed scheme here could be embedded into such communication networks which employ this mechanism to be a complement to its security, without increasing the computational complexity significantly.…”

“…Based on the randomness and privacy features of channel, Faria et.al firstly proposed a scheme in [9] to detect identity-based attacks by using the signal strength information, namely, the instantaneous signal-to-noise ratio (SNR). Xiao et al proposed the authentication methods using the CSI information in [10]- [12], and then extended the PHY authentication methods to multiple-input multiple-output (MIMO) systems [13] [14] and orthogonal frequency-division multiplexing (OFDM) systems [15].…”

Traditional solutions handle security at the application layer, which causes huge signaling overhead and long delay if authentication is implemented for every signal to enhance the security of wireless communication systems. In this paper, a realtime and two-way authentication method is proposed, which is based on the characteristics of radio channel including randomness and privacy. For the proposed method, the unique instant channel state information (CSI) can be used to authenticate the transmitter. In frequency- and time-selective fading channels, the current estimated CSI is compared with the predicted CSI, which is implemented at the previous frame, in order to authenticate the validation of the received signal. Both the hypothesis testing and mutual information measure methods are used for authentication determination, and the Mont Carlo simulation results verify the efficiency of the proposed method.
