arXiv:2605.22898v1 Announce Type: new Abstract: Federated learning protocols face a structural trilemma: canonical server-based aggregation~\cite{mcmahan2017} creates a single point of failure and gradient inversion risk; decentralised ring-gossip alternatives~\cite{hu2019segmented} expose classification heads to semi-honest peers via uninformed uniform weights; and personalised methods~\cite{collins2021exploiting} reintroduce central aggregation. No existing protocol simultaneously achieves server-free operation, permanently private heads, ring topology, and principled asymmetric neighbour we
The increasing adoption of federated learning in privacy-sensitive applications necessitates more robust and secure aggregation methods, addressing prior limitations in decentralised and personalised approaches.
This research introduces a novel protocol that addresses key vulnerabilities in federated learning, offering a significant step towards more secure, private, and decentralised AI development, particularly relevant for sensitive data domains.
The proposed FIRMA protocol offers a server-free, permanently private head, ring topology, and principled asymmetric neighbour weighting, fundamentally altering how federated learning could be implemented for enhanced privacy and security.

Widespread adoption could lead to more resilient and private federated learning deployments across healthcare, finance, and other regulated industries.
Increased privacy by design might accelerate the integration of AI into highly sensitive areas previously constrained by data security concerns.
This could foster new competitive dynamics in AI development, favouring decentralised models and reducing the dominance of platforms requiring central data aggregation.
