Sealed storage for trusted cloud computing

In cloud computing, cloud user´s sensitive data is in the control of a third part, which will lead to considerable risk on the privacy and security of the data. To address this problem we propose a trusted cloud computing platform with sealed storage ability (TSSC). TSSC enable Infrastructure as a Service provider (IaaS) such as Amazon EC2 to provide remote attestation to the IaaS user by an attestation delegation server and seal the IaaS user´s sensitive data with their desired integrity of the IaaS configuration. We implement our solution on Xen, and present a simple prototype based Nimbus. Our evaluation results show that the performance overhead of the solution is acceptable.
