Examining the Security of a File System Interface to OceanStore

To support existing applications, global-scale storage systems of the future will require a file system interface. Such an interface must be carefully designed in order to maintain the secure, fault-tolerant properties of the underlying system. In this paper, we develop the OceanStore File System, a file system interface to OceanStore. We examine many of the security issues that arise in designing such an interface, focusing especially on information exposed through traffic analysis and denial...
