… conventional multiuser diversity achieves with no security requirement. To address this issue
and to effectively exploit the multiuser diversity for secure relay networks, in this paper, we …

… -hop relay network consisting of a source (Alice) and a destination (Bob) communicating via
an untrusted AF relay. … During the second phase, the relay forwards the signals to Bob. The …

… Then, for both OFT and NOFT schemes, we consider the secure transmission design to
maximize secure transmission throughput under the secrecy outage constraint. …

… 1, we consider a relay network consisting of one source (S), several relays (Rl,l = 1, 2,...),
one destination (D), and several eavesdroppers (Ej, j = 1, 2,...). All the nodes are equiped with …

… antennas at the relay, we propose a heuristic twostage relay processing scheme to enhance
the security of a dual-hop relaying network. According to this scheme, the relay first uses …

… For CTWR networks, physical layer security is an important … for cooperative secure transmission
in CTWR networks, which … information security for PTs, we introduce the CT as the relay …

… the development of PHY security issues in untrusted relay networks. Then important issues
… trusted relay networks are discussed. Following that we present a case study of AF relaying …

… , we investigate the secure transmission in two-way untrusted amplify-andforward relay
networks with … Two secure SWIPT relaying strategies, namely secure power splitting (SPS) and …

… sourcerelay-destination link. For secure transmission, our aim is to prevent the untrusted relay
… during the source-to-relay and relay-to-destination transmission phases, respectively. For …

… networks with opportunistic relay selection. In [35], [36], the authors have studied the PHYsecurity
of two-way AF relay networks with effective relay … security of two-way AF relay networks …
