摘要：Now-a-days, there is a revolutionary trend to use cloud services, so more customers are attracting to use public cloud storage. Data storage outsourcing to cloud storage servers is an emerging trend among many firms and users. To relieve from the burden of storage management, broad data access with independent geographical locations and economizing of expenditure investment on software, hardware and maintenance, most of the organizations are outsourcing their data management operations to external service providers. The most attractive part of the cloud computing is the computation outsourcing with its uniqueness, which is becoming the major research area and also getting paid more attention and interest from both academia and industry. As research is progressing day-by-day, obstacles of cloud computing are getting into the focus of vision, simultaneously few challenges are getting solved, and few solutions are better optimized. Among the new born or existing, the challenge which is in most limelight always is security of the outsourced data. Consequently data owner neither have any control on hosted data nor on hosted data centers. Number of techniques addressed this problem, to ensure data security and integrity hosted in cloud. But all of them have their own limitations. In this paper, we propose a new model of CP-ABE, which uses hardware parameters such as cloud instances, server configurations are used in the setup, key generation, encryption and decryption phases.
