Research of Fine Grit Access Control Based on Time in Cloud Computing

As the wildly application and rapidly development of cloud computing, the security of cloud technology has been raising more and more attention. The technology of access control in cloud plays the key role in the whole application system. This paper introduces the traditional theory and models of access control. Then, the unique challenges in cloud access control and the corresponding solutions are analyzed. On the basis of these researches, the Time-restrained Fine-grit Access Control Model in Cloud is proposed. The features of this model are analyzed in the following. In the final of this paper is the summary of the whole research and the expectation in future research direction.
