Abstract: -Cloud storage allows users to remotely store their information and revel in the on-demand prime quality cloud applications while not the burden of native hardware and software system management although the advantages are clear, such a service is additionally relinquishing users’ physical possession of their outsourced information, that inevitably poses new security risks towards the correctness of the info in cloud. In order to handle this new downside and any deliver the goods a secure and dependable cloud storage service, we tend to propose during this paper a flexible distributed storage integrity auditing mechanism, utilizing the homomorphic token and distributed erasure-coded information. The proposed style permits users to audit the cloud storage with terribly light-weight communication and computation price. The auditing result not solely ensures robust cloud storage correctness guarantee, however additionally at the same time achieves quick information error localization, i.e., the identification of misbehaving server. Considering the cloud information are dynamic in nature, the projected style any supports secure and economical dynamic operations on outsourced information, as well as block modification, deletion, and append. Analysis shows the projected scheme is extremely economical and resilient against Byzantine failure, malicious information modification attack, and even server colluding attacks
