云计算可以让公司根据需要外包计算来降低成本。但是，就目前看来，云计算对其客户

提供的服务并不核实保密性和数据计算的完整性。

为了解决这个问题，我们提出了一个值得信赖的云计算平台（TCCP）设计，TCCP 使得

基础设施即服务（IaaS）能够提供像Amazon EC2 那样的封闭环境，保证客户虚拟机的保

密性。此外，它还允许客户在启动他们的虚拟机前，向IaaS 提供商证明服务是安全的。-Cloud computing allows companies to outsource calculations needed to reduce costs. However, the current view, cloud computing services to its customers does not verify the calculation of confidentiality and data integrity. To solve this problem, we propose a trusted cloud computing platform (TCCP) design, TCCP makes the infrastructure as a service (IaaS) to provide as a closed environment like Amazon EC2 to ensure the confidentiality of client virtual machines. In addition, it allows customers to start their virtual machines prior to the certification service provider IaaS is safe.
