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.

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 ...

Wireless Physical Layer Security
EURASIP Journal on Wireless Communications and Networking, 2009 Security is a critical issue in multi-user wireless networks in which secure transmissions are becoming increasingly difficult to obtain in highly mobile and distributed environments. Interest in this area has exploded since 2000, motivated by the rise of wireless networking in general and by the increasing interest in large mobile networks with light ...

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.
