Abstract: Cloud computing started a new era for IT enterprises. It allows the movement of application from local to remote location, massive data storage. Owner has access to centralized or decentralized data storage server, where data management handled by remote vendor. But, the heterogeneous and dynamic nature of cloud introduces security challenges. Among them, access control and integrity checking are most important which incur high consideration. Attribute-based encryption is one of the access control technique which allows integration of access policies, attributes, and encrypted data. In this paper, a new fine-grained decentralized data access control technique with user revocation has been proposed. Here, service provider is responsible for verifying the user authenticity. The proposed schema supports integrity checking and user revocation. The integrity checking proof validates that the user data is intact and revocation mechanism will help to revoke the user in linear time. Moreover, the proposed access control and authentication schemes are decentralized and comparable to other approaches.
