Secrecy Rate

Secrecy rate quantifies the rate at which information can be transmitted securely, preventing eavesdropping. Current research focuses on maximizing secrecy rate in various communication scenarios, particularly wireless networks, employing techniques like graph neural networks (GNNs) for efficient bandwidth allocation and user scheduling, and exploring the interplay between secrecy rate and other performance metrics such as latency and utility in semantic communication. These advancements are crucial for enhancing security in diverse communication systems, from space-air-ground integrated networks to quantum key distribution, improving the robustness and efficiency of secure communication protocols.
