Cloud computing is one of the today's most exciting technologies due to its abilities like ensuring scalable services, reducing the burden of local hardware and software management associated with computing while increasing flexibility and scalability. A major feature of the cloud services is that user's data are usually processed remotely in unknown machines. Though there are many conveniences brought by this new technology, there are some issues such as cloud computing servers can be easily compromised, data is no longer under the control of the data owner and cloud computing is not responsible for the access control of outsourced data desired by the data owner. To address these problems, we propose a new framework known as Secure Flexible Framework (SFF). This proposed framework allows data owner to achieve cloud data integrity, actual data usage tracking and fine grained access control of outsourced data. Through this paper, we strengthen the correctness and user's control of their own data in the cloud along with scalable, flexible and fine grained access control of outsourced data.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
