Enabling Data Security in Cloud Computing Using Third Party Auditing and Encryption Services
Cloud Computing is the next-generation architecture of computing. It moves the software and databases to the large data centers, where the management of the data and services can face a number of challenges. By outsourcing data, users are free from the burden of local data storage and maintenance. However, since the users does not have physical possession of large size of outsourced data makes the data integrity protection in cloud computing a very challenging task for users. So public auditability for cloud data storage security is important where users can entrust an external audit party to check the integrity of outsources data when needed. To securely introduce an effective third party auditor (TPA), the following requirements have to be met: 1) TPA should be able to efficiently audit the cloud data storage without the local copy of data, and should not introduce any additional on-line burden to the cloud user; 2) The third party auditing process should preserve user data privacy.
