The challenges facing physical layer security

IEEE Communications Magazine, 2015
There 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 ...

Jamming Strategies for Physical Layer Security

IEEE Wireless Communications, 2018
This 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.

Quantization for Physical Layer Security

2016 IEEE Globecom Workshops (GC Wkshps), 2016
We propose a multi-level CSI quantization and key reconciliation scheme for physical layer security. The noisy wireless channel estimates obtained by the users first run through a transformation, prior to the quantization step. This enables the definition of guard bands around the quantization boundaries, tailored for a specific efficiency and not ...

Securing massive MIMO at the physical layer

2015 IEEE Conference on Communications and Network Security (CNS), 2015
We consider a single-cell downlink massive MIMO system in the presence of an adversary capable of jamming and eavesdropping. We show that, classical attacks of eavesdropping and data jamming can be simultaneously rendered useless. Specifically, we show that, the secure degrees of freedom (DoF) attained in the presence of classical attacks is as same as

Transmit Beamforming for Layered Physical Layer Security

IEEE Transactions on Vehicular Technology, 2019
In 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.

Physical Layer Security

2021
This book studies the vulnerability of wireless communications under line-of-sight (LoS) and non-LoS correlated fading environments. The authors theoretically and practically provide physical layer security analyses for several technologies and networks such as Fifth-Generation (5G) networks, Internet of Things (IoT) applications, and Non-orthogonal ...

A Rateless Approach to Physical-Layer Security

2018 IEEE International Conference on Communications (ICC), 2018
A 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.

Physical Layer Security

2018
Wireless communications’ infrastructures are frequently selected as a cable replacement in many applications, giving an immediate advantage on the wireless investment. However, the worldwide proliferation of wireless local area network (WLAN) imposed large investments on the network security.

Stopping sets for physical-layer security

2010 IEEE Information Theory Workshop, 2010
Physical-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.
