SAFE: Secure Aggregation with Failover and Encryption

Year: 2025
Type: article
Abstract: We propose, analyze, and experimentally evaluate a novel secure aggregation algorithm targeted at cross-organizational federated learning applications with a fixed set of participating learners. Our solution organizes learners in a chain and encrypts all traffic to reduce the controller of the aggregation to a mere message broker. We show that our algorithm scales better and is less resource demanding than existing solutions, while being easy to implement on constrained platforms. With 36 nodes, our method outperforms state-of-the-art secure aggregation by 70x, and 56x with and without failover, respectively.
