Privacy Preserving in TPA for Secure Cloud- Survey

Abstract- Cloud users can remotely store their data and appreciate the on-demand high quality applications and services from a shared pool of configurable computing resources, regardless of local data storage and maintenance. However, the fact that users no longer have physical possession of the outsourced data makes the data integrity protection in Cloud computing a formidable task, especially for users with constrained computing resources. This paper study the the problem of ensuring the integrity of data storage in Cloud Computing. In particular, we task of allowing a third party auditor (TPA), on behalf of the cloud client, to verify the integrity of the dynamic data stored in the cloud. To securely introduce an effective third-party auditor (TPA), and determine various techniques and algorithms for strengthen the Security. Keywords- TPA, Cloud Computing, CSP, RSA
