Abstract

Multiparty Computation (MPC) is a technology that enables computations to be performed without exposing private data. Three main approaches are employed to construct an MPC: secret-sharing schemes, homomorphic encryption, and garbled circuit. Although secret-sharing based MPC involves lower communication cost generally, it requires more round communications for concrete protocols such as comparisons or interval tests. Herein, we propose a five-round secure comparison protocol and a five-round interval test protocol using a shuffling protocol based on a three-party secret-sharing scheme. Additionally, we compare our protocols with existing protocols based on rounds and multiplications.
