Practical Secure Aggregation for Federated Learning on User-Held Data
Not on the map. Why?
Abstract (arXiv)
Secure Aggregation protocols allow a collection of mutually distrust parties, each holding a private value, to collaboratively compute the sum of those values without revealing the values themselves. We consider training a deep neural network in the Federated Learning model, using distributed stochastic gradient descent across user-held training data on mobile devices, wherein Secure Aggregation protects each user's model gradient. We design a novel, communication-efficient Secure Aggregation protocol for high-dimensional data that tolerates up to 1/3 users failing to complete the protocol. For 16-bit input values, our protocol offers 1.73x communication expansion for 210 users and 220-dimensional vectors, and 1.98x expansion for 214 users and 224 dimensional vectors.
