-Everyday operations of modern enterprises heavily depend on their information processing capability, and the costs and overheads of managing them bring about the serious challenges. In order to relieve the burdens of IT resources and of maintaining them by professionals, cloud computing is introduced. CLOUD computing is a new computing paradigm that is constructed on virtualization, aligned and circulated computing, utility computing, and service oriented architecture. The advantages of cloud computing include decreased charges and capital expenditures, expanded operational efficiencies, scalability, flexibility, immediate time to market, and so on. Cloud storage is a basic service which has been widely used today. However, due to network security or trust to Cloud Storage service Providers (CSP), and other security incidents, many individuals and businesses are afraid to upload their own important or private data to the cloud storage servers. Thus, the access control security of cloud storage has become the focus of research in cloud storage filed. In this paper we propose a deployment model (SB-CP-ABE) for ABE which enables management of access rights as well as efficient key refreshing and revocation.
Cloud computing is one of today's most exciting technologies due to its ability to reduce costs associated with computing while increasing flexibility and scalability for computer processes. Cloud computing is set of resources and services offered through the Internet. The rapid growth in field of "cloud computing" also increases severe security concerns. Lack of security is the only hurdle in wide adoption of cloud computing. Distribution and sharing of File is one of the most critical service of cloud computing. This paper examines security for "big data" environments, reviewing built-in protections and weaknesses of these systems. In this paper, we use the Hadoop based file system and secure it using a highly secure algorithm based on ciphertext policy attributes based encryption with pairing (CP-ABE-WP with pairing). The solution aims at providing optimal performance in cloud environment and also ensures security by using a session based approach. The proposed method has maintained a hierarchy of users to ensure that files are used by their appropriate users.
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.
