High-Throughput Universally Composable Threshold FHE Decryption

Guy Zyskind, Doron Zarchy, Max Leibovich, Chris Peikert

Abstract

Threshold Fully Homomorphic Encryption (FHE) enables arbitrary computation on encrypted data, while distributing the decryption capability across multiple parties. A primary application of interest is low-communication multi-party computation (MPC), which benefits from a fast and secure threshold FHE decryption protocol.
