Abstract:

   This document describes Verifiable Distributed Aggregation Functions
   (VDAFs), a family of multi-party protocols for computing aggregate
   statistics over user measurements.  These protocols are designed to
   ensure that, as long as at least one aggregation server executes the
   protocol honestly, individual measurements are never seen by any
   server in the clear.  At the same time, VDAFs allow the servers to
   detect if a malicious or misconfigured client submitted an invalid
   measurement.  Two concrete VDAFs are specified, one for general-
   purpose aggregation (Prio3) and another for heavy hitters (Poplar1).
