Secure Deduplication of Data using ABE with Hybrid Cloud

The technique Attribute-based encryption has been widely used in cloud computing where a data provider outsources his/her encrypted data to a cloud, and can share the data with users who satisfies the possessing credentials. Unfortunately the standard ABE system does not support secure deduplication, which is important for eliminating duplicate copies of identical data in order to save cloud storage and the network bandwidth. The term deduplication of data in cloud refers to the elimination of duplicate or redundant data or file especially from the cloud. The paper is a variant of the paper proposed by Hui Cui and Robert Hdeng that focuses on the concept of ABE. Though method is secure for data and save storage space in the cloud, it is not efficient and effective in its performance. In the proposed system, encryption is performed using the combination of AES and CPABE. It enhances the performance of secure storage using hybrid cloud.
