Secure physical layer network coding versus secure network coding

, 2018
Secure network coding realizes the secrecy of the message when the message is transmitted via noiseless network and a part of edges or a part of intermediate nodes are eavesdropped.

Secrecy Rate-Optimum Energy Splitting for an Untrusted and Energy Harvesting Relay Network

IEEE Access, 2018
In this paper, a destination-assisted-jamming-based secure transmission is devised for an untrusted and energy harvesting relay network. In the proposed scheme, both source and destination split their energies into two parts for energy harvesting at the ...

Cooperative jamming for energy harvesting multicast networks with an untrusted relay

IET Communications, 2017
Recently, there are increasing requirements of security in wireless communications, especially for the multiuser systems. In this study, the authors consider the security of two‐hop cooperative multicast networks with an untrusted relay. An energy harvesting destination aided cooperative jamming framework is proposed to protect information from being ...

Joint Power Allocation at the Base Station and the Relay for Untrusted Relay Cooperation OFDMA Network

International Journal of Antennas and Propagation, 2015
The secure communication that multiple OFDMA-based cell-edge mobile stations (MS) can only transmit confidential messages to base station (BS) through an untrusted intermediate relay (UR) is discussed.

Joint power control for untrusted relay cooperation-based confidential communication

Tongxin xuebao, 2014
The scenario that multiple cell-edge mobile stations (MS) all without direct-links to the base station (BS) but have confidential messages in the uplink in the presence of untrusted relay (UR) cooperation was considered.In order to implement the secure ...
