—We suggest a method of controlling the access to a secure database via quorum systems. A quorum system is a collection of sets (quorums) every two of which have a nonempty inter...
A quorum system is a collection of sets (quorums) every two of which intersect. Quorum systems have been used for many applications in the area of distributed systems, including mu...
Quorum systems are a mechanism for obtaining fault-tolerance and efficient distributed systems. We consider geographic quorum systems; a geographic quorum system is a partition of...
It is considered good distributed computing practice to devise object implementations that tolerate contention, periods of asynchrony and a large number of failures, but perform f...
There are many essential applications for quorum systems in ad-hoc networks, such as that of location servers in large-scale networks. Existing research proposes many approaches t...
Probabilistic quorum systems can tolerate a larger fraction of faults than can traditional (strict) quorum systems, while guaranteeing consistency with an arbitrarily high probabi...

Replicated services accessed via quorums enable each access to be performed at only a subset (quorum) of the servers and achieve consistency across accesses by requiring any two qu...
Abstract. This paper describes e cient protocols for multi-party computations that are information-theoretically secure against passive attacks. The results presented here apply to...
Abstract With n servers that independently fail with probability of p < 0.5, it is well known that the majority quorum system achieves the best availability among all quorum sys...
