Protected Data Objects Replication in Data Grid
Secret distribution and erasure convention - based approaches have been used in distributed storage systems to provide the confidentiality, integrity, and availability of critical information. To achieve performance goals in data accesses, these data fragmentation approaches can be combined with dynamic replication. In this paper, the authors consider data partitioning (both secret distribution and erasure convention) and dynamic replication in data grids, in which security and data access performance are critical issues. More specifically, they investigate the problem of optimal allocation of sensitive data objects that are divided by using secret distribution scheme or erasure convention scheme and/or replicated.
