Remote data integrity checking is a crucial technology in cloud computing. Recently, many papers focus on providing data dynamics and / or public verifiability to such protocols. Existing protocols can support both features with the help of a third-party auditor. Cloud storage data has become a trend. Increasing numbers of customers store their important data on remote servers in the cloud, without leaving a copy on their local computers. Sometimes, data stored in the cloud is so important that customers should make sure that it is not lost or damaged. While it is easy to check the integrity of the data after completely downloading the data to be checked, downloading large amounts of data just to check the integrity of the data is a waste of communication bandwidth.
