A Futuristic Work on Distributed Storage and Multiple Audition in Cloud Computing

A flexible distributed storage enhances integrity auditing mechanism, utilizing the homomorphism token. The distributed erasure-coded data also enabled. The proposed design is concentrated mainly to audit the cloud storage with very lightweight communication and computation cost. The auditing result not only ensures strong cloud storage correctness guarantee, but also simultaneously achieves fast data error localization. The fast data error localization is nothing but the identification of misbehaving server. However the cloud data are dynamic in nature, the proposed design further supports secure and efficient dynamic operations on outsourced data. The operation includes block modification, deletion, and append. Analysis shows the proposed scheme is highly efficient and resilient against Byzantine failure. It is nothing but the malicious data modification attack, and even server colluding attacks.
