Most of the physical-layer authentication methods are based on the pre-knowledge of the channel information and the threshold is fixed before the communication process. In this paper, we propose a physical layer authentication method based on channel information and machine learning with a dynamic threshold in wireless communication environment. In this method, the threshold of the channel differences...
In this paper a physical layer transmission method based on the channel prediction and users quality-of-service(QoS) is proposed. The time-varying Rayleigh fading channel is predicted by back propagation neural network (BPNN), which will serve as judging whether the system secure transmission capacity is redundant. Then a scheme to choose the best physical layer security coding under the secure transmission...
This study investigates the framework of associating multiple-input–multiple-output (MIMO) beamforming with secure code to achieve unconditional secure communications in the wireless passive eavesdropping environment. The schemes are based on a two-step method under Wyner's wiretap channel model. First, with MIMO transmit beamforming, one can utilise the spatial degree of freedom to cripple eavesdroppers’...
