UAV Swarm-Enabled Aerial CoMP: A Physical Layer Security Perspective

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 ...

Wireless 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...

Cross Layer Security Protocol Using Swarm Intelligence

Security and privacy plays a vital role in wireless applications such as health monitoring, military and biometric identification systems. Due to the limited resource constraints in wireless sensor network, security in protocols is sacrificed or kept minimal. In this paper, a cross layer protocol is designed to detect denial of service attack imposed on the network by malicious nodes. The Denia...

Artificial Interference Aided Physical Layer Security in Cache-enabled Heterogeneous Networks

Caching popular contents is a promising way to offload the mobile data traffic in wireless networks, but so far the potential advantage of caching in improving physical layer security (PLS) is rarely considered. In this paper, we contribute to the design and theoretical understanding of exploiting the caching ability of users to improve the PLS in a wireless heterogeneous network (HetNet). In s...
