摘要: Semi-passive replication is a variant of passive that does not rely on group membership service. Defago et al. [4] defined the semi-passive concept in crash fault model and described algorithm based lazy consensus algorithm. In this paper, we consider semipassive for Byzantine model. We present algorithms two system models: 1) with synchronous communication partially processing, 2) an asynchronous augmented unreliable detectors faults. prove our provide safety liveness. Our are optimal good runs, having latency degree 2. describe how can be tuned to obtain desired levels resilience or efficiency presence also optimizations improve performance
