An active or adaptive eavesdropper is an adversary that can act as both an illegitimate
receiver and hostile jammer, rendering any communication between parties unsecured. An …

Fundamental problems in wireless mobile telecommunication systems in urban
environments are fast and slow fading, and interchannel interference. These problems …

In this paper, we study a physical layer security improvement method for a multi-user
cooperative non-orthogonal multiple access (NOMA) system in the presence of an adaptive …

We propose a novel non-orthogonal multiple access (NOMA)-inspired jamming and relaying
scheme to enhance the physical layer security of untrusted relay networks. Particularly …

본 논문에서는 다수의 비신뢰 중계기가 존재하는 중계망에서 중계 프로토콜과 중계기 선택에
따른 물리계층 보안 성능을 분석한다. 구체적으로 인공잡음 (artificial noise) 전송 및 상쇄를 …

The rapidly-evolving fifth-generation (5G) wireless system needs to satisfy requirements in
terms of low latency, throughput, high energy efficiency, network capacity, and improved …

In this paper, we focus on the half-duplex (HD) relaying with partial relay selection (PRS)
scheme using destination-assisted jamming (DAJ). We consider one source (S), one …

In this paper, we investigate secure communication for an untrusted relay network, in which
a source equipped with NS antennas communicates to M users with the help of an untrusted …

A new breed of" information-based" agents aims to deliver effective negotiators to Internet
commerce. They are founded on concepts from information theory, and are designed to …
