摘要：Generally the secret sharing and erasure coding-based approaches is used in distributed environmentsystems to ensure the confidentiality. To achieve this performance in data grid we provide data fragmentationapproaches and it is combined with dynamic replication. In this paper, we consider data partitioning (both secretsharing and erasure coding) and dynamic replication in data grids, in which security and data access performance arecritical issues. In a grid, effective way to improve data accessibility and data accessing efficiency is by data replication.This paper also propose an cryptographic infrastructure to protect privacy from users with administrative privileges.The cryptographic methods are done using the DES techniques. The replication is done using Dynamic replicationalgorithm. We use Simple Bottom-Up which is a method used for the dynamic replication. Data partitioning is doneusing IDA Algorithm and the encrypted keys are also partitioned for the security of the sensitive data in the distributedenvironment.
