ANALYSIS OF DATA SECURITY IN CLOUD USING THIRD PARTY AUDITOR: REVIEW
Abstract
Cloud is kind of centralized database where many organizations/clients store their data, retrieve data and possibly modify data. Data stored and retrieved in such a way may not be fully trustworthy so here concept of TPA(Third Party Auditor) is used. TPA makes task of client easy by verifying integrity of data stored on behalf of client. In cloud, there is support for data dynamics means clients can insert, delete or can update data so there should be security mechanism which ensure integrity for the same. Here TPA can not only see the data but he can access data or can modify also so there should be some security mechanism against this. Cloud Computing has been envisioned as the next-generation architecture of IT Enterprise. It moves the application software and databases to the centralized large data centres, where the management of the data and services may not be fully trustworthy. This unique paradigm brings about many new security challenges, which have not been well understood. The introduction of effective TPA eliminates the involvement of the client through the auditing of whether his data stored in the cloud is indeed intact, which can be important in achieving economies of scale for Cloud Computing.
