Abstract: Trusted computing platform develops rapidly in these years, but research on policy control system under trusted computing platform is not enough. To supply the gap, this paper represents a brand new policy control solution for trusted computing which uses XrML technology. The system is fit for the requirement of trusted computing platform and it also affords more ability of control, configuration and extension. How to applie the system on Microsoft NGSCB platform is represent.

摘要： 近几年可信计算平台发展迅速，但基于可信计算平台上的策略控制系统的研究相对落后，现有的一些策略控制系统无法满足新式的可信计算平台的需要。经过对可信计算平台关于策略控制需求的认真分析，结合最新的XrML技术，该文提出了一套策略控制系统，该系统的控制力度、可配置性、可扩展性更为优越，基本符合可信计算平台的需求，将其应用到了微软的NGSCB平台上。
