An improved trusted cloud computing platform model based on DAA and Privacy CA scheme
Security and privacy are two prime barriers to adoption of the cloud computing. To address this problem on Infrastructure-as-a-Service model, a trusted cloud computing platform model has been proposed to provide a closed box execution environment that guarantees confidential execution of guest virtual machines. However this model has significant drawbacks that it relies on the trusted third party outside of the cloud circumstance too much. In this paper we show how to address this issue based on the neutral feature of the Trusted Platform Module. By moving the responsibility of managing trusted platforms from the trusted third party to the trusted platforms of Infrastructure-as-a-Service model, our improved TCCP model achieves higher availability, reliability and safety.
