Secure Transmission With Aid of a Helper for MIMOME Network Having Finite Alphabet Inputs
IEEE Access, 2017 This paper considers secure transmission with the aid of a helper for finite alphabet signals in multiple-input-multiple-output multiple antenna eavesdropper networks, where the helper transmits a jamming signal along with the confidential message sent ...

Robust Power Allocation and Outage Analysis for Secrecy in Independent Parallel Gaussian Channels
, 2015 This letter studies parallel independent Gaussian channels with uncertain eavesdropper channel state information (CSI). Firstly, we evaluate the probability of zero secrecy rate in this system for (i) given instantaneous channel conditions and (ii) a ...

Effective Secrecy Rate for a Downlink NOMA Network [PDF]
IEEE Transactions on Wireless Communications, 2019 In this paper, a novel approach is introduced to study the achievable delay-guaranteed secrecy rate, by introducing the concept of the effective secrecy rate (ESR). This study focuses on the downlink of a non-orthogonal multiple access (NOMA) network with one base station, multiple single-antenna NOMA users and an eavesdropper.

Secure Energy Harvesting Relay Networks With Unreliable Backhaul Connections
IEEE Access, 2018 Wireless backhaul is a cost-effective and flexible alternative to wired backhaul, yet it suffers from unreliability. This paper studies the secrecy performance of a relay network with such unreliable wireless backhaul.

Some New Results on the Multiple-AccessWiretap Channel
Entropy, 2014 In this paper, some new results on the multiple-access wiretap channel (MAC-WT) are provided. Specifically, first, we investigate the degraded MAC-WT, where two users transmit their corresponding confidential messages (no common message) to a legitimate ...

On the Optimality of Secret Key Agreement via Omniscience
, 2018 For the multiterminal secret key agreement problem under a private source model, it is known that the maximum key rate, i.e., the secrecy capacity, can be achieved through communication for omniscience, but the omniscience strategy can be strictly ...
