Transmit Beamforming for Layered Physical Layer Security
IEEE Transactions on Vehicular Technology, 2019In this paper, we propose a novel layered physical layer security model, which is the extension of the traditional physical layer security to the domain of multiple-layer information security. It has a hierarchical information security structure that every transmitted message has a security level, while every user has a security clearance.

Jamming Strategies for Physical Layer Security
IEEE Wireless Communications, 2018This article provides a comprehensive overview on jamming strategies in the physical layer for securing wireless communications. As a complement to traditional cryptography-based approaches, physical layer based security provisioning techniques offer a number of promising features that have not been previously available.

A Rateless Approach to Physical-Layer Security
2018 IEEE International Conference on Communications (ICC), 2018A majority of coding constructions for physical-layer security are based on linear block codes and their cosets. One issue with these codes is that they require knowledge of channel state information (CSI) for both the friendly party and the eavesdropper in the wiretap channel prior to constructing the code.

The challenges facing physical layer security
IEEE Communications Magazine, 2015There has recently been significant interest in applying the principles of information-theoretical security and signal processing to secure physical layer systems. Although the community has made progress in understanding how the physical layer can support confidentiality and authentication, it is important to realize that there are many important ...

Stopping sets for physical-layer security
2010 IEEE Information Theory Workshop, 2010Physical-layer security based on wiretap codes can be used to complement cryptographic applications at higher layers of the protocol stack. We assume a passive eavesdropper that has access to noise-corrupted codewords with erasures that are statistically independent to those of the legitimate communication partners.

Physical Layer Security Assisted 5G Network Security
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017After 4G network becomes a global commercial success, the researchers are now looking at the future 5G technologies, both in standardization bodies and in research projects. Researchers find that the security architecture used in 4G can not satisfy the needs of 5G.
