Enabling Public Verification and Prove Shared Data Consistency in Cloud

  R. Jayaraghavan,  A. Selvakumar

The cloud service allows users to store and share their data with relative ease. Unfortunately these data are stored in untrusted servers and maintaining integrity of these shared data is skeptical, also the system hardware and software failure also affect the data integrity. There are several mechanisms defined to allow the public auditor to verify the integrity of data, but these existing mechanisms reveal identity of data owners. By using ring signature mechanism, the public auditor can audit the shared data without compromising user identity. The athos (AuTHenticated Outsourced Storage) is a platform independent architecture that allows authentication of outsourced data in untrusted storage. In this paper we utilize both ring signature and athos architecture for efficient public auditing and ensuring data freshness (latest version of stored data) of shared data.

Keywords- Ring signature, athos (AuTHenticated Outsourced Storage), Data freshness, public auditing
