Preserving Confidentiality through Public Auditing In Secure Cloud Storage
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 10
Abstract
Now a day users no longer have physical presence of the outsourced data which makes the data security stronger. Moreover, users should be able to just use the cloud storage as if it is local, without worrying about the its integrity. Therefore several critical security challenges are occur and motivate the researchers for further investigations. Because of this critical issues users can resort to a third party auditor (TPA) to check the integrity of outsourced data. To securely introduce an effective TPA, the auditing process should bring in no new vulnerabilities towards user data privacy, and introduce no additional online burden to user. In this paper, we propose a secure cloud storage system supporting privacy-preserving public auditing. We further extend our result to enable the TPA to perform audits for multiple users simultaneously and efficiently. Extensive security and performance analysis show the proposed schemes are provably secure and highly efficient.
