Distributed wireless networks often employ voting to perform critical network functions such as fault-tolerant data fusion, cooperative sensing, and reaching consensus. Voting is implemented by sending messages to a fusion center or via direct message exchange between participants.

Exploiting the physical in cyber-physical systems: On the practical use of physical-layer information to enhance system security [PDF]
This thesis argues that cyber-physical systems are, by their very nature, at risk from physical-layer attacks as well as cyber attacks. The proliferation of cheap and easy-to-use sensing and actuation technologies has drastically lowered the bar for ...

Physical Layer Security in N-Pair NOMA-PLNC Wireless Networks
In this paper, the effective end-to-end secure communication of N-pair cellular network is studied. Promising multiple access scheme known as non-orthogonal multiple access (NOMA) and physical layer network coding (PLNC) scheme are employed to improve ...

Directional modulation enabled physical-layer wireless security [PDF]
Directional modulation (DM), as a promising keyless physical-layer security technique, has rapidly developed within the last decade. This technique is able to directly secure wireless communications in the physical layer by virtue of the property of its ...

Physical Layer Security Using Two-Path Successive Relaying
Relaying is one of the useful techniques to enhance wireless physical-layer security. Existing literature shows that employing full-duplex relay instead of conventional half-duplex relay improves secrecy capacity and secrecy outage probability, but this ...

Physical Layer Security Enhancement with Reconfigurable Intelligent Surface-Aided Networks
Reconfigurable intelligent surface (RIS)-aided wireless communications have drawn significant attention recently. We study the physical layer security of the downlink RIS-aided transmission framework for randomly located users in the presence of a multi ...

Physical Layer Security in the Presence of Interference [PDF]
We evaluate and quantify the joint effect of fading and multiple interferers on the physical-layer (PHY) security of a system consisted of a base-station (BS), a legitimate user, and an eavesdropper. To this end, we present a novel closed-form expression for the secrecy outage probability, which takes into account the fading characteristics of the ...

Channel-Aware Randomized Encryption and Channel Estimation Attack
In this paper, we study the channel-aware (CA) randomization for a simple physical-layer encryption scheme and show that the probability of successful attack becomes very low by CA randomization when the known plain-text attack is carried out.
