Cloud computing, a type of computing paradigm that highly depends on shared data resources rather than local data resources which allow the devices to handle the applications. With the rapid development of cloud data services, the data in cloud was stored and shared across numerous users. Since the shared data can be accessed and modified by multiple users, this new paradigm poses huge challenges in keeping the integrity of the shared data. Several studies about the secure data retrieval focuses heavily on providing strict security for the data stored in the third party domain. However, strict security on third party domain will requires stupendous cost and security issues on cloud service provider which inevitably affects the efficient data retrieval in clouds. In this paper, we propose an effective scheme that supports the efficient retrieval of data stored in clouds. This paper is a survey of specific issues brought by the use of attributes based encryption system in a cloud computing system. © BEIESP.
