A Simple Secure Auditing for Cloud Storage

Cloud storage is a common service for users to store their important data in the cloud. It provides a dynamic, scalable storage place for any sort of user on-demand. From small businesses to corporations, the cloud is convenient as well as cost efficient so businesses won’t need to pay for their own hardware. Hardware for storage is updating so rapidly that it is difficult for companies to keep up with the maintenance and cost. The cloud can store vast amounts of data which becomes a target for people who want sensitive data. Some cloud service providers have been known to manipulate data that has been stored into their servers. This paper searches an efficient way to test audits for data integrity. A SOA model is introduced, including owners of data, the cloud server, and a TPA to test audits. The proposed method specially uses public cryptography in its framework. A signature is added to the method to increase validity and security of the communicating parties. This method not only solves the problem of the traditional method of checking for data integrities, but also improves current proposed methods.
