Anonymous aggregation for lightweight multiparty computations

Constantinos Patsakis

Abstract

While multiparty computations are becoming more and more efficient, their performance has not reached the needed level to be widely deployed for many applications. Nevertheless, the heterogeneous environment of modern computing needs this functionality to provide users their right to privacy. For a wide range of applications there is no need for complex computations, operations such as multiplication or addition might be sufficient. In this work we introduce the concepts of Anonymous Aggregation and Anonymous Aggregators, two lightweight cryptographic primitives that can perform specific private computations efficiently in restricted environments.
