Abstract
In this paper, we discuss a general methodology for analysis and modeling of trust relationships in
distributed computing. We discuss the classification of trust relationships, categorize trust
relationships into two layers and provide a hierarchy of trust relationships based on a formal
definition of trust relationship. We provide guidelines for the analysis and modeling of trust
relationships. We review operations on trust relationships and relative types of trust relationships in
our previous work. We provide a set of definitions for the properties of direction and symmetry of
trust relationships. In order to analyze and model the scope and diversity of trust relationship, we
define trust scope label. We provide some example scenarios to illustrate the proposed definitions
about properties of trust relationship. All the definitions about the properties of trust relationships
are elements of the taxonomy framework of trust relationships. We discuss the lifecycle of trust
relationships that includes the analysis and modeling of trust relationships, trust relationships at
runtime, and change management of trust relationships. We propose a trust management
architecture at high level to place the analysis and modeling of trust relationships under the
background of trust management.
