A scheme to ensure data security of cloud storage

Cloud storage offers great convenience to users. However, the data security concerns may impede cloud storage wide adoption. Although there are many schemes to solve the problem, they mostly focus on an aspect of data security. They have not a detailed discussion about the data security in cloud. In this paper, we proposed approach provides a scheme to allow users to check the integrity of their data in the cloud. We also present the performance criteria about the scheme, which can help the researchers to optimize their mechanism efficiently and effectively. The scheme is lightweight, efficient and robust.
