In this paper we present two protocols for asynchronous Byzantine Quorum Systems (BQS) built on top of reliable channels—one for self-verifying data and the other for any data. ...

Probabilistic quorum systems can tolerate a larger fraction of faults than can traditional (strict) quorum systems, while guaranteeing consistency with an arbitrarily high probabi...
Byzantine quorum systems [13] enhance the availability and efficiency of fault-tolerant replicated services when servers may suffer Byzantine failures. An important limitation of...

The use of good random numbers is essential to the integrity of many mission-critical systems. However, when such systems are replicated for Byzantine fault tolerance, a serious i...
: Provide application processes with strong agreement guarantees despite failures is a fundamental problem of fault-tolerant distributed computing. Correct processes have not to be...
