Third Party Public Auditing For Shared Data InThe Cloud Using ECC
Journal Title: International Journal of engineering Research and Applications - Year 2017, Vol 7, Issue 8
Abstract
A Third Party Auditor audits the shared data in thecloud without any modification of the data content.To provide thesecurity for cloud data a TPA can check the integrity of shareddata.The third party auditor can be able to audit the integrity ofdata without accessing the entire data from the cloud.The filesare divided into blocks and allow the TPA to audit the data witha specified block.If a new user wishes to join the group, TPAapproves the user and added to the group.A public auditingmechanism that verifies the integrity of data stored in the cloudwith the help of a digital signature, which can be aggregatedto each block of data.The proposed scheme provides an efficientuser revocation mechanism i.e. when a user revoked from thegroup, to resign the blocks that are signed by that revokeduser.The proposed scheme also supports dynamic operations suchas update, delete and insert operations.The TPA handles multipleauditing tasks at a time with batch auditing protocol.
