Secure Physical Layer Network Coding versus Secure Network Coding [PDF]

Entropy, 2021
When a network has relay nodes, there is a risk that a part of the information is leaked to an untrusted relay. Secure network coding (secure NC) is known as a method to resolve this problem, which enables the secrecy of the message when the message is ...

Cooperative Jamming-Based Physical-Layer Group Secret and Private Key Generation [PDF]

Entropy
This paper explores physical layer group key generation in wireless relay networks with a star topology. In this setup, the relay node plays the role of either a trusted or untrusted central node, while one legitimate node (Alice) acts as the reference ...

Security–reliability tradeoff analysis of untrusted energy harvesting relay networks

International Journal of Distributed Sensor Networks, 2018
We investigate secure communications in untrusted energy harvesting relay networks, where the amplify-and-forward relay is an energy constrained node powered by the received radio frequency signals, and try to unauthorizedly decode the confidential ...

High-Rate Cross-Channel Entanglement Swapping Between Independent On-Chip Sources. [PDF]

Adv Sci (Weinh)
To interconnect individual chip‐based quantum sources, high‐performance entanglement swapping is indispensable. Here, using low‐loss silicon chips with waveguide structure and frequency‐offset pumps, this work demonstrates high‐rate cross‐channel entanglement swapping.
