摘　　要：分析信任链相关研究的当前发展水平,提出细粒度信任链和细粒度系统软件信任链的思想,阐明只有细粒度信任链才能描述现实应用的真实情况。根据问题空间的复杂性,提出细粒度信任链建模的问题分解方法。该方法通过逐步拓展的策略,首先建立细粒度系统软件信任链模型,然后在此基础上建立完全的细粒度信任链模型。The state of the art of relevant research on chain of trust is figured out. The concepts of fine-grained chain of trust and fine-grained chain of trust of system software are put forward. It is argued that only fine-grained chain of trust can describe the genuine scenario of real world application. According to complexity of the problem space in question, a two-step approach is proposed for modeling fine-grained chain of trust, in which the first step is to model the fine-grained chain of trust of system software,and the second step is to model the complete fine-grained chain of Trust.
