摘　　要：针对目前在云计算环境中用户虚拟计算环境不可信的问题,利用可信平台模块虚拟化技术,在云服务器端为用户构造一个虚拟可信平台模块,然后以虚拟可信平台模块为基石,为用户在云服务器端构造了一个虚拟的可信计算环境,从而使现有的云计算用户中虚拟计算环境的可信情况获得了有效保障。通过与现有的可信平台模块虚拟化方案作对比发现,所提方案不仅周全地考虑了在云计算中虚拟机效率损耗的相关问题,而且相较显著提高了它的安全性和执行效率,更加适合被应用于用户虚拟计算环境。Aiming at the problem that the user’s virtual computing environment is untrusted in the cloud computing environment,a trusted platform module virtualization technology is used to construct a virtual trusted platform module for users on the cloud server side.Then,based on the virtual trusted platform module,a virtual trusted computing environment is constructed for users on the cloud server side,so that the credibility of the virtual computing environment among existing cloud computing users is effectively guaranteed.Compared with the existing virtualization solutions of trusted platform modules,it is found that the proposed scheme not only considers the related issues of virtual machine efficiency loss in cloud computing,but also significantly improves its security and execution efficiency.It is more suitable for being applied to a user’s virtual computing environment.
