چکیده انگلیسی

Cloud Computing has been emerged as a prominent technology where users can upload their data and do their processing using shared resources. But there always exist a tradeoff between the performance and security of a system. The same is applicable for cloud systems also. One of the major drawback associated with Cloud computing is related to its data privacy concerns, because the service provider can access the user data on the cloud at any point of time. Hence they could accidentally or intentionally distribute, modify or even delete our information. Hence the owner should have implemented mechanisms for preventing unauthorized access to his information. This paper proposes a secure cloud environment for storing user's files which is also capable of granting fine grained access control to data. Basic cryptographic schemes along with bivariate λ-degree, symmetric polynomials are utilized for achieving this. A flexible user access revocation scheme has also been proposed.
