Apr 11, 2019 · Based on null-space beamforming, we propose two different transmission schemes when the number of relay nodes is large enough. One scheme is ...

PDF | We investigate the physical-layer security problems of two-way relay networks in this paper. The whole network consists of two legitimate users.

No matter how many intermediate nodes in the communication networks, one can find suitable transmission schemes to ensure communication security, ...

In this paper, we investigate physical-layer transmission security problem of a two-way relay wireless network consisting of two legitimate terminal nodes ...

Dec 2, 2022 · A novel full-duplex (FD) relaying jamming scheme is proposed to achieve simultaneously information reception, EH and jamming signal transmission at the ...

Enhance secure communications in a two-way relay network with relay chatting. Proposed scheme maximizes mutual information and confuses eavesdropper.

We propose a model for securely exchanging data between two users with a two-way relay, where two users and the relay encrypt the exchanged data using data ...

Mar 2, 2017 · We show that our scheme is secure under three different adversarial models: (1) untrusted relay attack model, (2) trusted relay with ...
