Improving Key Generation Performance on Public Cloud Storage Along with User Legitimacy Verification

Abstract

in the cloud storage systems, data management is very difficult to the service providers as well as data owners. To manage the stored data, we used Ciphertext-Policy Attribute-Based Encryption (CP-ABE) & it has been followed as a promising method to offer flexible, fine-grained & secure records get entry to manipulate for cloud storage with honest-but-curious cloud servers. However, inside the present CP-ABE schemes, the single attribute authority ought to execute the time-consuming consumer legitimacy verification and secret key distribution, and therefore it outcomes in a single-factor overall performance bottleneck when a CP-ABE scheme is adopted in a big-scale cloud storage device. In this paper, we recommend a novel heterogeneous framework to do away with the problem of single-factor performance bottleneck and offer an extra efficient get entry to manipulate scheme with an auditing mechanism. The proposed scheme can not only eliminate the single-point performance bottleneck but also be able to present a robust, high-efficient, & secure access control for public cloud storage.
