ePrint Report: Willow: Secure Aggregation with One-Shot Clients

James Bell-Clark, Adrià Gascón, Baiyu Li, Mariana Raykova, Phillipp Schoppmann

A common drawback of secure vector summation protocols in the single-server model is that they impose at least one synchronization point between all clients contributing to the aggregation. This results in clients waiting on each other to advance through the rounds of the protocol, leading to large latency even if the protocol is computationally efficient. In this paper we propose protocols in …
