Cloud computing is an appealing paradigm that provide users to store large volume of data and to use application over cloud without any infrastructure investment. When processing such application will generate large volume of intermediate data set which is often stored in the cloud to save the cost of re-computation. For preserving those generated intermediate dataset encrypting all the dataset is handled but this is cost consuming process, and consume lot of storage space and maintenance cost. Among those intermediate dataset some may be used in future and some may not but encrypting all kind of intermediate dataset is widely adopted in existing approach.
