Client-specific Property Inference against Secure Aggregation in Federated Learning

1 code implementation7 Mar 2023 Raouf Kerkouche, Gergely Ács, Mario Fritz

We formulate an optimization problem across different rounds in order to infer a tested property of every client from the output of the linear models, for example, whether they have a specific sample in their training data (membership inference) or whether they misbehave and attempt to degrade the performance of the common model by poisoning attacks.

Constrained Differentially Private Federated Learning for Low-bandwidth Devices

no code implementations27 Feb 2021 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

This bandwidth and corresponding processing costs could be prohibitive if the participating entities are, for example, mobile devices.

Compression Boosts Differentially Private Federated Learning

no code implementations10 Nov 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia, Pierre Genevès

In this paper, compressive sensing is used to reduce the model size and hence increase model quality without sacrificing privacy.

Federated Learning in Adversarial Settings

no code implementations15 Oct 2020 Raouf Kerkouche, Gergely Ács, Claude Castelluccia

This paper presents a new federated learning scheme that provides different trade-offs between robustness, privacy, bandwidth efficiency, and model accuracy.
