Separating Broadcast from Cheater Identification

Year: 2025

Type: conference-paper

Abstract: Secure Multiparty Computation (MPC) protocols that achieve Identifiable Abort (IA) guarantee honest parties that if they are denied output, they will be notified of the identity of at least one corrupt party. Cheater identification provides recourse in the event of a protocol failure, and in some settings---such as key management---can even be desired over Guaranteed Output Delivery. However, unlike the weaker security with abort setting, IA protocols make integral use of a broadcast channel.
