A SECURE ALGORITHM FOR DATA DEDUPLICATION IN CLOUD STORAGE SYSTEM

Abstract

Data redundancy is a significant issue that wastes plenty of storage space in the cloud-fog storage integrated environments. Most of the current techniques, which mainly center around the static scenes, for example, the backup and archive systems, are not appropriate because of the dynamic nature of data in the cloud or integrated cloud environments. This problem can be effectively reduced and successfully managed by data deduplication techniques, eliminating duplicate data in cloud storage systems. Implementation of data deduplication (DD) over encrypted data is always a significant challenge in integrated cloud-fog storage and computing environment to optimize the storage efficiently in a highly secured manner. This paper develops a new method using AES, Blowfish and RSA algorithms over the cloud and fog environment to construct secure deduplication systems. The proposed method focuses on the two most important goals of such systems. On one side, the redundancy of data needs to be reduced to its minimum, and on the other hand, a robust encryption approach must be developed to ensure the security of the data. Our approach found the advantage of the RSA encryption algorithm over the existing Attribute-based encryption. Which makes the advantage of symmetric key encryption and performed the fast process over the existing work scenario to prove the efficiency of our algorithm? Our work is computed using the parameter computation time which is efficient than the existing attribute-based encryption algorithm.
