Physical layer security transmission mechanism of relay network based on artificial noise

Xiangyu Li, Liang Jin, Kaizhi Huang

Untrusted relay in self-organizing wireless network will lead to serious security threats.This paper proposed a physi-cal-layer security mechanism based on interference nodes.The transmission was divided into two phases: first,sent signal with artificial noise from the sender and interference nodes to relay,second,restored the original information by receiver with the help of interference nodes.As the signal received by the relay and the eavesdropper were always accompanied with severe interference,security of the system was well guaranteed.Simulation results show that,when the eavesdropper and interference nodes are in different locations,the system always has a large secure-transmission rate.

Information Security Technology of Wireless Communication Physical Layer Based on Airspace Technology

Jiang Lan

Due to the characteristics of the broadcast function of the wireless communication network, the problem of information security has become very serious. And because the traditional upper-layer encryption technology is accompanied by the advancement of computer technology and eavesdropping technology, it has become more and more far from being able to meet the needs of modern society for information security. The multi-antenna beamforming technology in the airspace technology is a technology that can effectively increase the strength of the legal signal and suppress the eavesdropping signal. Therefore, it has become the most important technology in the physical layer security of our country and deserves our attention. Therefore, this article aims to study the wireless communication physical layer information security technology based on airspace technology. Based on the analysis of the basic theory of physical layer security, the current status of physical layer security research and the airspace physical layer security technology, the artificial noise auxiliary technology is promoted and applied to security identification. Taking the speed of maximizing the safe frequency spectrum as the design goal, an algorithm for joint optimization of information noise beam and artificial noise beam is proposed. The simulation results show that this algorithm can effectively improve the security and stability of the system, and it can also solve the eavesdropping problem.

Key Technologies of 5G Wireless Communication Network Physical Layer Based on Information Security Early Warning Model

Yifeng He, Yinyu Wei, Jiadong Cao

With the continuous development of the fifth generation (5G) technology, the physical layer of the wireless communication network is facing new challenges. How to effectively prevent and protect these key technologies in the physical layer has a great impact on the entire network and even the entire society. Information security early warning model is a state evaluation model of important security control points in the physical layer of communication network. Security is an important indicator of communication system. Whether its security protection is effective is the basis of its survival and use. Aiming at the situation that the receiver is monitored in the transmission system, this paper has studied the safe transmission method assisted by artificial noise (AN). After the simulation experiment of the physical layer security transmission algorithm, this paper discussed the performance of different algorithms in three scenarios: transmission under non ideal channel information, one-way relay eavesdropping system, and multiple input multiple output (MIMO) untrusted relay eavesdropping system. When analyzing the relationship between the safe transmission rate of different MIMO untrusted relay antennas and the target power constraint $A_{T}, M_{y}=5, M_{d}3, M_{t}=4, A_{t}=\{5,35\}$ dB. On this basis, the optimal power distribution was realized. In the six schemes, when the power constraint $A_{T}$ increased, the security transmission rate of each scheme was improved.

Secure and Interference-Free Transmission in Wireless Multiuser Networks

Hongliang He, Nengcheng Chen, Di Gao +2 more

This letter investigates the physical-layer security of multi-user networks and proposes a secure and interference-free transmission scheme. The scheme constructs the transmitted signals of different users by using the characteristics of the Hadamard matrix, and injects self-interference and artificial noise that can be eliminated by legitimate users but not by eavesdroppers, thereby significantly improving security. We analyze the asymptotic security performance and obtain the secrecy outage probability when the number of users is large enough. Finally, simulation results exhibit the security performance of the proposed scheme.

Self-Interference Assisted Cooperative Jamming for Secure Communications

Hongliang He, Xingmei Li

In this paper, we propose a self-interference assisted cooperative jamming scheme to guarantee the security of wireless communication. Different from the traditional cooperative jamming schemes where artificial noise is designed in one phase (or one time slot), we design artificial noise in multiple phases. Moreover, we innovatively introduce carefully designed self-interference in the transmitted signals, which not only guarantees transmission efficiency, but also further enhances security. We first analyze the number of eavesdropping antennas on the security performance and then obtain the secrecy rate. Finally, simulation results corroborate our theoretical analysis.
