ABSTRACT
Cloud computing hasbeen thegenuinesolution tothe rising storage costs of IT Enterprises.The costofdatastorage devices is too high rate at which datais being generated, where the enterprises orindividual users to frequently update theirhardwareor software. The data outsourced tothecloudwould help inreducing themaintenance.Theuser’s dataare moved from cloudto large datacenters, which are located remotely which does nothave control over it. Hence there is a securitybreech which has to beresolved. To address thisissue, we proposeaneffectivemethodtoachievesecureand dependable cloud storageby usingdistributed storage integrityauditingmechanism,which incorporatehomomorphic token anddistributed erasure-coded data for dynamicallystoring data.The proposed design allows the userwith lightweight communication and computationcost. To maintainreliablecloud storage correctness,and to locatethemisbehaving serverinwhich thedata arefrequently changingincloud. It isanefficient method for dynamic operation whichinclude erase, append, and block modification and itvery effective in fighting against server colludingattacks, byzantinefailure, maliciousdata blockmodifications.
