针对可信虚拟平台信任链的形式化分析问题,建立了包括虚拟机和虚拟信任根在内的可信虚拟平台完整的信任链模型,并详细定义其应满足的信任属性,通过扩展LS2,验证了可信虚拟平台信任链模型能够有条件地满足其正确性、唯一性。对实例系统分析表明本文所建立信任链模型的通用性及基于扩展LS2分析方法的有效性。
Considering the effective formal analysis for the trust chain of the trusted virtualization platform, a trust chain model which includes the virtual machine and the virtual root of trust, was proposed firstly with the detail definition of the trusted properties. Through extending the LS2, it verified the correctness and uniqueness of the trust chain formally under some conditions. Analysis for the photosystern-shows the generality of the proposed trust chain model and the va- lidity of the analysis method based on the extended LS2.
