B-Detector: A Quorum-based Method for Byzantine Fault Detection
Byzantine fault tolerance masks Byzantine faults through replicated replicas. But three or even more times of resource requirement are not acceptable in most resource demanding scenarios. Fault detection makes a good tradeoff between resource requirement and fault tolerance effect. But related works mainly focus on liveness property of the agreement and atomic-broadcast algorithms in case of the benign faults,there are no much works on Byzantine fault detection so far. We propose a quorum-based Byzantine fault detection method — B-Detector. B-Detector monitors message among different nodes by proxy transport,collects application state assertions,detects Byzantine faults caused by equivocation and software bug through consistency check and auditing,provides verifiable evidence to third party. Experiment results prove effectiveness of B-Detector in distributed environment.
