Physical Layer Security Performance Analysis of Hybrid FSO/RF Communication System

Physical Layer Security in Wireless Communication Networks

Physical layer (PHY) security has become an emerging area of research recently. Wireless networks use unguided medium as communication channels, so gathering wireless data transmission is easier when compared to traditional cable systems. With the rise of new security challenges, many different solutions have been offered and are being developed. However, maintaining security in wireless networ...

Wireless Communication Security Through Symbol Obfuscation in Physical Layer

Secure communication is a critical and challenging issue in wireless networks. To achieve the information theoretic secrecy the leading approach is artificial noisy symbol. The basic idea in this paper is enhancing the security in wireless communication. Multiple Inter-symbol Obfuscation(MIO) method will be deployed in the physical layer. MIO is a method for transferring the data and it provide...

The Physical Layer Security Experiments of Cooperative Communication System with Different Relay Behaviors

Physical layer security is an attractive security mechanism, which exploits the randomness characteristics of wireless transmission channel to achieve security. However, it is hampered by the limitation of the channel condition that the main channel must be better than the eavesdropper channel. To alleviate the limitation, cooperative communication is introduced. Few studies have investigated t...

Physical Layer Security Issues

Conventional wired networks are subject to being tapped by a variety of means, whether copper or fiber connections are used. In addition, methods of network snooping exist that make such eavesdropping minimally invasive, but no less significant. Wireless networking has additional characteristics that also decrease physical network security. As new technologies emerge, the potential for loss of ...
