Key Generation for Outsourced Storages in Clouds

Sandeep.S, Vijayakumar.P, Anand.V

In this paper we proposed a key generation and third party audit algorithm for verifying the integrity of untrusted and outsourced storage in cloud. Our audit service is developed according to these techniques, splitting and merging, random sampling, dynamic auditing, and index hash table, supporting provable updates to outsourced data and timely anomaly detection. In addition to that we proposed a method based on periodic verification for improving the audit service performance. Our experimental results not only validating the effectiveness approaches, but also show our audit system verifies the integrity with lower computation overhead and also requiring less storage for audit meta data.
