The paper proposes PCDM, a diffusion-based framework that enables highly stealthy and effective data poisoning attacks against Federated Learning systems, significantly degrading global performance while evading detection.
This paper proposes a Row-Movable Active Reconfigurable Intelligent Surface (RM-A-RIS) system for vehicular semantic communication, enhancing spatial diversity and improving Sum-Semantic Spectral Efficiency (Sum-SSE) by up to 132.9% compared to passive RIS.
