abstract = "Federated learning (FL) aims to derive a “better” global model without direct access to individuals{\textquoteright} training data. It is traditionally done by aggregation over individual gradients with differentially private (DP) noises. We study an FL variant as a new point in the privacy-performance space. Namely, cryptographic aggregation is over local models instead of gradients; each contributor then locally trains their model using a DP version of Adam upon the “feedback” (e.g., fake samples from GAN – generative adversarial networks) derived from the securely-aggregated global model. Intuitively, this achieves the best of both worlds – more “expressive” models are processed in the encrypted domain instead of just gradients, without DP{\textquoteright}s shortcoming, while heavyweight cryptography is minimized (at only the first step instead of the entire process). Practically, we showcase this new FL variant over GAN and meta-learning, for securing new data and new tasks.",
