Data Link Bridge (DLB) - A Coding Algorithm for Security Enhancement in Cloud Data Storage

Sheik Khadar Ahmad Mnoj, D Lalitha Bhaskari

Cloud storage model has become a widely accepted solution for the increasing demand for online storage and ubiquitous access. Cloud Service Providers (CSP) offers cloud services to the cloud customers (CC). The security and privacy still remain a major concern for the CC to upload data to the cloud. The advancement in cyber-attacks and insider attacks are enforcing CC to doubt the efficiency of the existing encryption algorithms being adopted. The present paper attempts to make customers adhere to cloud storage by introducing a coding-based encryption algorithm named Data Link Bridge (DLB), which is implemented on the client-side. The proposed DLB algorithm not only assures data security but also produces a lesser size of cipher in comparison with other encryption algorithms resulting in a faster data transfer to and fro from cloud servers. Furthermore, the DLB algorithm does not require any key for encryption rather it produces a key that can be retained at the client premises bestowing control over the cloud data. Experimental results have demonstrated that the proposed method works satisfactorily for encrypting and decrypting the data efficiently.
