Enhancing Physical Layer Security in Wireless Networks with Cooperative Approaches
Motivated by recent developments in wireless communication, this thesis aims to characterize the secrecy performance in several types of typical wireless networks. Advanced techniques are designed and evaluated to enhance physical layer security in these networks with realistic assumptions, such as signal propagation loss, random node distribution and non-instantaneous channel state information...
متن کاملPhysical Layer Security Schemes for Full-Duplex Cooperative Systems: State of the Art and Beyond
Due to the broadcast nature of wireless medium, wireless communication is highly vulnerable to eavesdropping attack. Traditionally, secure wireless data transmission has relied on cryptographic techniques at the network layer which incur high computational power and complexity. As an alternative, physical layer security (PLS) is emerging as a promising paradigm to protect wireless systems by ex...
متن کاملPhysical 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 ...
متن کاملWireless Physical Layer Security
Security in wireless networks has traditionally been considered to be an issue to be addressed separately from the physical radio transmission aspects of wireless systems. However, with the emergence of new networking architectures that are not amenable to traditional methods of secure communication such as data encryption, there has been an increase in interest in the potential of the physical...
متن کاملPhysical layer security for multi-user MIMO systems
T his thesis studies physical layer security for multi-user multiple-input multiple-output (MIMO) wireless systems. Due to the broadcast nature of the physical medium, wireless multi-user communications are very susceptible to eavesdropping, and it is critical to protect the transmitted information. Security of wireless communications has traditionally been achieved at the network layer with cr...
