SECURED AND DEPENDABLE STORAGE IN CLOUD COMPUTING USING HOMOMORPHIC

Abstract

Cloud storage allows users to remotely store their knowledge and revel in the on-demand top quality cloud applications while not the burden of native hardware and software system management. Although the advantages area unit clear, such a service is additionally relinquishing users’ physical possession of their outsourced knowledge that inevitably poses new security risks towards the correctness of the info in cloud. so as to deal with this new downside and any win a secure and dependable cloud storage service, we have a tendency to propose during this paper a versatile distributed storage integrity auditing mechanism, utilizing the homomorphism token and distributed erasure-coded knowledge. The projected style permits users to audit the cloud storage with terribly light-weight communication and computation price. The auditing result not solely ensures sturdy cloud storage correctness guarantee, however additionally at the same time achieves quick knowledge error localization, i.e., the identification of misbehaving server. Considering the cloud knowledge area unit dynamic in nature, the projected style any supports secure and economical dynamic operations on outsourced knowledge, as well as block modification, deletion, and append. The projected theme is very economical and resilient against Byzantine failure, malicious knowledge modification attack, and even server colluding attacks.
