Abstract


Cloud data security and privacy protection is generally considered to be the two major cloud computing development, So far, however, no means can prove to upload their own data and the integrity and confidentiality of the application, resulting in customers with cloud services The question of trust between providers, which will become one of the biggest obstacle to hinder the development of cloud computing. Combination of trusted computing technology and cloud computing is one of the direction to solve this problem of trust, this infrastructure as a service (Infrastructure-as-a-Service, IaaS) model proposed by trusted cloud computing platform (Trusted Cloud Computing Platform, TCCP) solution in 2009. The trusted cloud computing platform model certified by an external trusted coordinator (Trusted Coordinator, TC) built-in credibility chip server, and then manage active trusted server list, and start to participate in a virtual machine (Virtual Machine) dynamic migration process. Monitor or trusted node (server) built-in the credibility chip and safe operation by trusted virtual machine monitor (Trusted Virtual Machine Monitor, TVMM) management to guarantee running inside the virtual machine data from hackers or privileged modified. However, because of the excessive dependence of the trusted third party, trusted cloud computing platform model can only remain in the theory in the exploratory stage, there is no practical feasibility. Depth study of this paper, the limitations of trusted cloud computing platform model, the proposed an improved based on direct anonymous attestation (Direct Anonymous Attestation, DAA) and Privacy Certification Center (Privacy Certification Authority, Privacy CA) strategy TCCP model, better way to solve the bottleneck problem in the performance and security of trusted third party. This article is mainly through the introduction of DAA strategy and designed according to the trusted chip neutral characteristics a part of the internal trusted node (Trusted Nodes, TNs) Privacy CAs (internal the small trusted third party) protocol, which within the Privacy CA assumed the TC the TNs management duties with the part of the certification responsibilities. Inside the cloud computing platform for each area (Zone) has a number of Privacy CA Privacy CA manage their own trusted area, take such a quarantine measures to improve the security of the platform, a Privacy The CA management area was broken to reduce losses to a minimum. These different management area Privacy CAs the internal trusted contacted elected by (Internal Trusted Coordinator, ITC) to contact, the ITC election of secure multiparty computation (Secure Multi-party Computation, SMC) algorithm, which guarantee the ITC election not be manipulated by a few rogue Privacy CAs affected. Privacy CAs elected ITC to completely replace the TC trusted node management function, and to participate in a virtual machine created with dynamic migration process. The difficulty here is how to make the the Privacy CA with ITC substitute TC most of the functions at the same time does not weaken the security of the platform. In the original trusted cloud computing platform model, the concept of virtual trusted platform directly from the introduction of the trusted platform architecture based on virtual technology inside, not explore the suitability of cloud computing platform. Virtual trusted platform architecture research, and the changes to the trusted platform architecture based on the the TCCP model of demand. This article taken cloud platform architecture based on open source Eucalyptus virtual trusted platform architecture based on vTPM, credible standard TPM 1.2 chip must comply with (DAA strategy under in TPM1.2 standards to be able to be used). Trusted cloud computing platform model credible chip to support this specialized security hardware, is one of the best way to solve the problem of the cloud computing privacy and security, especially in research and application of trusted computing technology is relatively mature. Has high reference value for the design of a trusted cloud computing platform model, this paper improved the original trusted cloud computing platform design ideas for the future platform design help, concerns about data security is no longer a cloud calculate one of the obstacles to the development.
