Multiparty Distributed Point Functions
Abstract
We present the first construction of multiparty distributed point functions based on one-way functions, where the share sizes remain sublinear in the domain size and grow {\em only polynomially} with the number of parties. In contrast, existing multiparty distributed point function constructions in Minicrypt have share sizes that grow {\em exponentially} with the number of parties.
