Byzantine quorum systems have been proposed that work properly even when up to f replicas fail arbitrarily. However, these systems are not so successful when confronted with Byzan...
We investigate issues related to the probe complexity of quorum systems and their implementation in a dynamic environment. Our contribution is twofold. The first regards the algo...
Replication is a mechanism extensively used to guarantee the availability and good performance of data storage services. Byzantine Quorum Systems (BQS) have been proposed as a sol...

Open distributed systems are typically composed by an unknown number of processes running in heterogeneous hosts. Their communication often requires tolerance to temporary disconn...

ÐIn this paper, we explore techniques to detect Byzantine server failures in asynchronous replicated data services. Our goal is to detect arbitrary failures of data servers in a s...
