TriVer: a lightweight and client-verifiable secure aggregation with dropout tolerance for federated learning

Journal of King Saud University: Computer and Information Sciences
Federated learning relies on a central server to aggregate client updates, making secure aggregation (SA) essential for privacy protection. Masking-based SA schemes dominate large-scale deployments due to their low overhead, yet they face a fundamental ...
