CLOUD STORAGE WITH LIGHT-WEIGHT COMMUNICATION AND COMPUTATION PRICE
N. Naveena, M. V. Panduranga Rao, Adeel Ahmed Khan · 2013
Cloud-based outsourced storage releases the client's burden for storage management and maintenance by providing a comparably low-cost, scalable, location-independent platform. 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 bow out users' physical possession of their outsourced information. In order to handle this new snag and any deliver the goods a secure and dependable cloud storage service, we tend to propose during this paper a novel distributed storage integrity reviewing mechanism, utilizing the homomorphism token and distributed erasure-coded information. The proposed style permits users to review the cloud storage with very light-weight communication and computation price. The reviewing result not solely ensures robust cloud storage correctness guarantee, however additionally at the same time achieves quick information fault 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 deceitful failure, malicious information modification attack, and even server colluding attacks.
