Sovereign Cognitive Digital Twins: Fusing 6G ISAC, AI-RAN, and Zero-Trust Edge Grids for National Resilience in the Global South

ArXiv feed covering emerging 5G/6G, edge, AI, vehicular networking, post-quantum TLS, and machine-learning security research. The most directly security-relevant themes are reliable data deletion in self-improving federated agents, gaps between PQ-TLS policy and deployment, zero-trust and sovereignty in 6G digital-twin architectures, and resilience of distributed edge and network-slicing systems. The entries describe research prototypes, measurements, and architectures rather than confirmed vulnerabilities or active exploitation.
