虚拟机动态迁移远程属性证明简

随着互联网和企业提高资源利用率，其基础技术虚拟化技术发展迅速。同时虚拟化的动态迁移，是实现资源调度灵活性和可行性必要条件。动态迁移涉及方面广，导致安全问题突出。在Xen虚拟化的平台下，引入了虚拟PCR（vPCR）和属性的概念，利用可信属性认证协议将数据与系统安全属性封装起来保护,同时保护多个虚拟机系统中数据的安全，不受虚拟机系统配置变化的影响，保证虚拟机动态迁移安全性。

Virtual machines Live migration Remote property Attestation

With the improvement of Internet and enterprise resource utilization, the basic technology of virtualization technology is developing rapidly. At the same time, the dynanfic nfigration of virtual, is the realization of resource schedulingflexibility and feasibility and necessary condition. Dynamic migration involves awide, cause security problems. In the Xen virtualization platform, the virtual PCR （vPCR） and attribute concept, using trusted attribute authentication protocol the data andsystem security attributes encapsulated protection. While protecting the data in muhiple virtual machine system of safety, not is influenced by the virtual machine system configuration change, ensure thesecurity of the migration of virtual machine dynamic
