Abstract

Cloud computing is an internet based computing which provides different users an opportunity to store their data in the cloud While data outsourcing relieves the owner of the burden of the local data storage and maintenance but as they have no longer physical possession of outsourced data makes data integrity protection a very challenging task This paper explores the secure cryptographic hash function along with some other techniques that can be used by TPA to ensure the integrity of data stored in the cloud at regular intervals or on user request
