Abstract:Secure multi-party computation (MPC) is a fundamental problem in secure distributed computing. The optimal resilience for perfectly-secure MPC in synchronous and asynchronous networks is t < n/3 and t < n/4 respectively, where n is the number of parties and t is the number of corruptions. A natural question is whether there exists a protocol tolerating t s < n/3 corruptions in a synchronous network and t a < n/4 corruptions in an asynchronous network. We design such a protocol, if 3t s + t a < n. For our proto… Show more
