Perfectly Secure Network-Agnostic MPC Comes for Free

본문 미리보기

Secure multiparty computation (MPC) allows a set of parties to jointly compute a function while keeping their inputs private. Classical MPC protocols assume either a synchronous or an asynchronous network. Synchronous protocols tolerate more corrupted parties but rely on a timing bound, while asynchronous protocols make no timing assumptions but handle fewer corruptions. The network-agnostic model aims to combine the advantages of both. It requires security without knowing in advance whether
