Performance Study of Untrusted Relay Network Utilizing Cooperative Jammer
Abstract—In this paper, the problem of secure transmission in two-hop amplify-and-forward (AF) systems with an untrusted relay is investigated. To prevent the untrusted relay from intercepting the source message and to achieve positive secrecy rate, the destination-based cooperative jamming (DBCJ) technique is used. In this method the destination sends an intended jamming signal to the relay. T...

متن کاملCooperative Relay Scheme for Delay and Energy Constrained Multicast Network
We propose the reception decision scheme and the distributed relay decision scheme to reduce the processing power consumption in the baseband and the redundant retransmission in non-orthogonal cooperative multicast network. By simulation, it is shown that the -outage constrained achievable multicast rate and energy efficiency achieved by proposed schemes are higher than ones by conventional sch...
متن کاملImproving Secrecy with Nearly Collinear Main and Wiretap Channels via a Cooperative Jamming Relay
In physical layer security (PHY-security), the frequently observed high correlation between the main and wiretap channels can cause a significant loss of secrecy. This paper investigates a slow fading scenario, where a transmitter (Alice) sends a confidential message to a legitimate receiver (Bob) while a passive eavesdropper (Eve) attempts to decode the message from its received signal. It is ...
