UnlinkableDFL: A Framework for Network-Layer Unlinkability in Decentralized Federated Learning

Chao Feng, Thomas Grubl, Jan von der Assen +4

Decentralized Federated Learning (DFL) removes the central aggregator of conventional Federated Learning, but peer-to-peer model exchange still exposes network traces: who communic…
