Secure and Efficient Deduplication Scheme based on Ownership Challenge for Mobile Cloud Environment
Cloud Computing plays a vital job in providing storage, infrastructure, and processing services. The demand for storing data in cloud is increasing day by day due to the large number of users. To protect the data stored in the cloud, data is often stored in an encrypted form. Cloud storage includes a large amount of duplicated data under different encryption schemes by different users. Existing solutions that deal with encrypted deduplication do not support controlled access, ownership revocation and file modification require uploading the entire file in encrypted form. In this paper, a scheme based on Incremental Proxy Re-Encryption (IPRE) scheme for deduplication with ownership challenge integrated with improved file modification operation in mobile cloud environment is proposed. The proposed scheme is compared with Proxy Re-Encryption (PRE) scheme based on turnaround time and energy consumption. During file modification operation, the proposed scheme shows remarkable improvement in results using the restricted storage and processing speed of mobile devices.
