Secrecy Enhancement of Cooperative NOMA Networks With Two-Way Untrusted Relaying
IEEE Access, 2020 The two-way relaying (TWR) technique has been confirmed to achieve higher spectral efficiency and average sum rate compared with the one-way relaying (OWR) technique in ultra-dense next generation networks with limited spectal resources.

On the Secrecy Capacity of Fading Channels
, 2006 We consider the secure transmission of information over an ergodic fading channel in the presence of an eavesdropper. Our eavesdropper can be viewed as the wireless counterpart of Wyner's wiretapper. The secrecy capacity of such a system is characterized

Secrecy Through Synchronization Errors
, 2015 In this paper, we propose a transmission scheme that achieves information theoretic security, without making assumptions on the eavesdropper's channel. This is achieved by a transmitter that deliberately introduces synchronization errors (insertions and ...
