一种安全VM-vTPM迁移协议的设计与实现

摘要

Based on the existing migration protocols of the vTPM, give some security requirements about secure VM-vTPM migration. Then, develop a new secure VM-vTPM migration protocol, explain the detail contents of every phases of this protocol and give its security evaluation. Finally, discuss its realization and performance overhead based on Xen Hypervisor.%在分析现有vTPM迁移方案的基础上提出了安全VM-vTPM迁移的安全需求,并针对这些安全需求,提出了一种新的安全VM-vTPM迁移协议.详细阐述了协议各阶段涉及的具体内客,并对其进行了安全评估.最后,基于Xen讨论了其实现及性能开支.
