Enhancing Security and Privacy in Federated Learning for Distributed Systems: The REMINDER Approach
摘要
Federated Learning (FL) enables collaborative model training without centralizing raw data, but distributed deployments remain exposed to typical poisoning and inference attacks and must operate across resource-constrained edge environments. The REMINDER project addresses these challenges by designing an edge-centric framework that provides privacy and security mechanisms with byzantine-robust learning approaches. This paper reports some of the project’s mechanisms and their implications for the development of robust and secure FL deployments, including: (i) a threat model addressing poisoning and inference risks; (ii) a modular architecture with differential privacy, secure authenticated updates, and robust aggregation against malicious clients; and (iii) two representative validation scenarios, such as eHealth and smart buildings, which ground design choices and highlight domain-specific constraints. Building on these contributions, the present work formalizes the end-to-end workflow, specifies component interfaces, and links attack classes to concrete mitigations within REMINDER, while outlining open challenges such as verifiable aggregation and the privacy–utility trade-off introduced by differential privacy in common FL settings.
