Byzantine fault-tolerant (BFT) state-machine replication makes it possible to design systems
that are resilient against arbitrary faults, a requirement considered crucial for an increasing …

Cloud infrastructures are highly favoured as a computing delivery model worldwide, creating
a strong societal dependence. It is therefore vital to enhance their resilience, providing …

We present two asynchronous Byzantine fault-tolerant state machine replication (BFT)
algorithms, which improve previous algorithms in terms of several metrics. First, they require …

One of the main reasons why Byzantine fault-tolerant (BFT) systems are not widely used lies
in their high resource consumption: 3 f+ 1 replicas are necessary to tolerate only f faults …

With the advent of trusted execution environments provided by recent general purpose
processors, a class of replication protocols has become more attractive than ever: Protocols …

随着分布式系统规模的增大, 设计复杂度也不断提升, 系统可靠性所面临的问题也越来越严峻.
