Traditional approaches to byzantine fault-tolerance have mostly avoided the problem of confidentiality. Current confidentiality-aware solutions rely on a heavy infrastructure investment or depend on complex key management schemes. The framework presented in this paper relies on a novel approach that combines byzantine fault-tolerance, secure storage and verifiable secret sharing to significantly reduce the additional infrastructure and complexity required by confidentiality protection. The proposed framework was compared to other solutions using a micro-benchmark, and an implementation of TPC-B and NFS.
