Secure Energy Harvesting Relay Networks With Unreliable Backhaul Connections
IEEE Access, 2018 Wireless backhaul is a cost-effective and flexible alternative to wired backhaul, yet it suffers from unreliability. This paper studies the secrecy performance of a relay network with such unreliable wireless backhaul.

A new achievable ergodic secrecy rate region for the fading multiple access wiretap channel [PDF]
2009 47th Annual Allerton Conference on Communication, Control, and Computing (Allerton), 2009 We give a new achievable ergodic secrecy rate region for the two-user fading multiple access wiretap channel. Our scheme creates a vector channel between the two transmitters and the intended receiver that has full-rank and creates another vector channel between the two transmitters and the eavesdropper whose rank is 1.

Security Tradeoffs in Rate Splitting Multiple Access: Optimal Signal Splitting vs Revealing [PDF]
, 2022 This paper considers the secrecy performance of rate splitting (RS) scheme in multi-user multiple-input single-output (MU-MISO) systems. The split of the users' messages into common and private parts can enhance the sum-rate of the communication systems.

Secure Rate Splitting Multiple Access: How Much of the Split Signal to Reveal? [PDF]
, 2022 Rate Splitting Multiple Access (RSMA) relies on multi-antenna rate splitting (RS) at the transmitter and successive interference cancellation (SIC) at the receiver. In RS the users’ messages are split into a common message and private messages, where the
