IEEE Transactions on Mobile Computing, 2018 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.

Techniques for Enhanced Physical-Layer Security [PDF]
2010 IEEE Global Telecommunications Conference GLOBECOM 2010, 2010 Information-theoretic security--widely accepted as the strictest notion of security--relies on channel coding techniques that exploit the inherent randomness of propagation channels to strengthen the security of communications systems. Within this paradigm, we explore strategies to improve secure connectivity in a wireless network.

Physical Layer Security in the Presence of Interference [PDF]
IEEE Wireless Communications Letters, 2017 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
IEEE Access, 2017 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.
