MaSTer: Maliciously Secure Truncation for Replicated Secret Sharing without Pre-Processing

The software extends the MP-SPDZ library for Multi-party computation protocols by an implementation of the MaSTer protocol (https://eprint.iacr.org/2024/1026). The extension includes full implementation of the MPC protocol integrated into the MP-SPDZ framework, together with benchmarking results. The repository is further extended by MIT-BIH (https://physionet.org/content/mitdb/1.0.0/) and PTB (https://www.physionet.org/content/ptbdb/1.0.0/) datasets, both available under the Open Data Commons Attribution License v1.0. The ECG heartbeat data is used for ML inference benchmarking, as specified in the paper.
