Abstract:

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 single-level 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 single-level and secondary-level indirect recommended trust relationship is presented, meanwhile, the possible losses in the transfer process of trust relationship is analyzed.

Key words: Internetware, direct trust relationship, recommended trust relationship, trust transfer, trust measurement
