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.

Fading Cognitive Multiple-Access Channels With Confidential Messages
, 2009 The fading cognitive multiple-access channel with confidential messages (CMAC-CM) is investigated, in which two users attempt to transmit common information to a destination and user 1 also has confidential information intended for the destination.

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
