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...
There are currently two approaches to providing Byzantine-fault-tolerant state machine replication: a replica-based approach, e.g., BFT, that uses communication between replicas t...

This paper presents robust emulation of multi-writer/multi-reader registers in message-passing systems using dynamic quorum con gurations. In addition to processor and link failur...
We investigate issues related to the probe complexity of the And-Or quorum system and its implementation in a dynamic environment. Our contribution is twofold: We first analyze th...
