Abstract:

As a kind of storage service that ownership is separated from administration authority, cloud storage facilitates user data management and access. However, in the cloud storage services, when the data are uploaded to the cloud, the data owners may lose the physical control of the data. How to ensure the integrity of the cloud data proposes an important challenge to the cloud storage. Existing data integrity verification schemes are based on the third-party verification, which gives the third-party too many authorities. If the third-party fails to verify the integrity of the data, and claims that the data are stored in cloud integrally, data owners will be deceived. In view of the above problems, this paper proposes a data integrity verification scheme for cloud storage based on the basic idea of bilinear mapping. The most important feature of the scheme is the ability to strengthen the control on the third party auditors which improves the ability of independent verification of data owners. At the same time, it can reduce the computation time of data owners.

Key words: cloud storage, integrity, independent verification, privacy protection
