SABE: Efficient and Scalable-Filtered Access Control in Distributed Cloud Data Storage

Distributed cloud data storage is an advanced and empirical concept in present days for outsourcing of data in cloud. A new decentralized grained access control approach is required for privacy on data storage that supports anonymous authentication. In this paper, we introduce to propose and develop an approach, i.e. Scalable Attribute-Based Encryption (SABE) to achieve grained with flexible and scalable access control in cloud computing for secure distributed cloud storage. SABE not only is scalable due to its pyramid structure, but also shares effective and flexible access control in supporting on ABE; it also assigns for user expiration time and revocation efficiently than existing schemas. Protected data transmission among users should be effective as well as flexible in order to support access control policy models with secure team communication, selective and hierarchal data transfer control in sharing. So in this paper, we propose and develop Transmitted Team Key Management (TTKM), where each client (user) in group shares a secret trust key owner with subsequent rekeying for data sharing join or departure of users requires only broadcast message between data sharing in cloud. We analyze the privacy of proposed TTKM schema and compare with existing SABE security schemas in distributed data sharing. Our experimental results show effective data access control with authorized security considerations.
