摘　　要：为了保证网构软件系统运行中的安全,文章提出一种对构件之间的信任关系进行分析与度量的方法。在网构软件中,构件之间信任关系包括直接信任关系和间接信任关系,间接信任又分为一级间接推荐信任和多级间接推荐信任。直接信任关系建立在构件交互基础上,可通过对交互过程中的行为进行统计分析获得,从而建立直接信任关系网。通过关系网中构件的前驱和后继确定信任推荐构件集,进而确定构件之间的间接推荐信任关系的级数,并对一级、二级间接推荐信任关系给出了对应的信任度量方法。同时,对信任关系在传递过程中可能会有的损失情况进行分析。In order to ensure the security of the Internetware system, this paper propose a method to analyze and measure the trust relationship among components. In Internetware system, the trust relationship among components can be divided into two types: direct trust relationship and indirect trust relationship. Indirect trust relationship includes singlelevel and multi-level recommended trust relationship. On the basis of original interaction among components, the direct trust relationship can be measured depending on the expected behavior in the interaction process. Direct trust relationship net can be built based on the relationship of direct trust. The trust recommendation component set can be found based on the precursor node list and successor node list in the net. At this time, the level of indirect trust relationship among components can be determined. The method to measure the singlelevel and secondary-level indirect recommended trust relationship is presented, meanwhile, the possible losses in the transfer process of trust relationship is analyzed.
