What is the SPDZ protocol?

The SPDZ protocol is a secure computation protocol for dishonest majority zero-knowledge, developed by the University of Bristol. It allows multiple participants to perform collaborative computations while protecting their privacy. The protocol includes techniques such as secret sharing, homomorphic encryption, and MACs to ensure security against malicious adversaries. SPDZ aims to facilitate secure multiparty computation tasks where parties can jointly compute functions without revealing their individual inputs.
