Distributed computation systems have become an important tool for scientiﬁc simulation, and a similarly distributed replica management system may be employed to increase the locality and availability of storage services. While users of such systems may have low expectations regarding the security and reliability of the computation involved, they expect that committed data sets resulting from complete jobs will be protected against storage faults, accidents and intrusion. We oﬀer a solution to the distributed storage security problem that has no global view on user names or authentication speciﬁcs. Access control is handled by a rendition protocol, which is similar to a rendezvous protocol but is driven by the capability of the client user to eﬀect change in the data on the underlying storage. In this paper, we discuss the beneﬁts and liabilities of such a system1 . Categories and Subject Descriptors H.2.7 [Database Management]: Database Administration—Security, integrity, ...
