A Multi-Layer Security Architecture for Smart-City IoT with Measured Limits: Edge Intrusion Detection, Screened Federated Learning and Ledger-Anchored Model Provenance

Smart-city platforms connect IoT devices across transport, energy, water, healthcare and e-government, so every gateway is an entry point. This paper evaluates a four-layer architecture—edge intrusion detection trained across districts by federated learning, digests anchored on a permissioned ledger, and a cloud orches...
