MPC for Securing Internet Infrastructure

Abstract

Secure multiparty computation (MPC) allows multiple entities to perform joint computation over their private inputs, revealing only the output. Although it was considered to be "not efficient enough" for many years, recent advances have shown that secure computation can be practical for specific applications. These applications have ranged from privacy-preserving auctions to private machine learning. In this work we explore the use of MPC for securing Internet infrastructure. We show that basic Internet systems, such as routing and DNS, rely on centralised authorities. Nevertheless, vulnerabilities as well as conflicting interests often make this requirement for trust not suitable for practical purposes. In this work, we set forth to explore replacement of trust in centralised authorities in Internet infrastructure with secure MPC.
