The authors believe that data storage security in cloud computing, an area full of challenges and of paramount importance, is still in its infancy now, and many research problems are yet to be identified. They envision several possible directions for future research on this area. To ensure the correctness of user's data in cloud data storage, they proposed an effective and flexible distributed scheme with explicit dynamic data support, including block update, delete, and append. To ensure the security of data, they proposed to use DES (Data Encryption Standards) algorithm.
