Abstract
Described is a system for secure multiparty computation. The system uses a secret sharing protocol to share secrets among servers of a synchronous network. An Open-Semi-Robust protocol or an Open Robust protocol is used to allow the servers to open their shares of secret data. If a server is corrupt, the Open-Robust protocol is used, otherwise, the Open-Semi-Robust protocol is used. A Deal-Semi-Robust protocol or a Deal-Robust protocol is utilized by a server to distribute its shares of secret data among the other servers. If a server is corrupt, the Deal-Robust protocol is used, otherwise, the Deal-Semi-Robust protocol is used. A Recover-Semi-Robust protocol or a Recover-Robust protocol is used to allow servers that were previously corrupted to recover their shares of secret data, such that each uncorrupted server holds correct shares of secret data. If a server is corrupt, the Recover-Robust protocol is used, otherwise, the Recover-Semi-Robust protocol is used.
