Abstract

A method for secure aggregation using public randomness is provided. The method includes determining, based on the public randomness from a random service beacon, a set of super-clients from a plurality of clients. The method further includes obtaining masked inputs from the clients and aggregated random values based on the set of super-clients. Each of the masked inputs is associated with a client from the plurality of clients and each of the aggregated random values is associated with a super-client from the set of super-clients. The method also includes aggregating the masked inputs from the plurality of clients and the aggregated random values from the set of super-clients.
