HyFL: A Hybrid Framework For Private Federated Learning

no code implementations20 Feb 2023 Felix Marx, Thomas Schneider, Ajith Suresh, Tobias Wehrle, Christian Weinert, Hossein Yalame

Federated learning (FL) has emerged as an efficient approach for large-scale distributed machine learning, ensuring data privacy by keeping training data on client devices.

ScionFL: Efficient and Robust Secure Quantized Aggregation

no code implementations13 Oct 2022 Yaniv Ben-Itzhak, Helen Möllering, Benny Pinkas, Thomas Schneider, Ajith Suresh, Oleksandr Tkachenko, Shay Vargaftik, Christian Weinert, Hossein Yalame, Avishay Yanai

In this paper, we unite both research directions by introducing ScionFL, the first secure aggregation framework for FL that operates efficiently on quantized inputs and simultaneously provides robustness against malicious clients.

CryptoSPN: Privacy-preserving Sum-Product Network Inference

no code implementations3 Feb 2020 Amos Treiber, Alejandro Molina, Christian Weinert, Thomas Schneider, Kristian Kersting

AI algorithms, and machine learning (ML) techniques in particular, are increasingly important to individuals' lives, but have caused a range of privacy concerns addressed by, e. g., the European GDPR.

Chameleon: A Hybrid Secure Computation Framework for Machine Learning Applications

no code implementations10 Jan 2018 M. Sadegh Riazi, Christian Weinert, Oleksandr Tkachenko, Ebrahim. M. Songhori, Thomas Schneider, Farinaz Koushanfar

Chameleon departs from the common assumption of additive or linear secret sharing models where three or more parties need to communicate in the online phase: the framework allows two parties with private inputs to communicate in the online phase under the assumption of a third node generating correlated randomness in an offline phase.
