Trust of a software system (i.e., the degree of confidence that a system conforms to its specification) can be defined in terms the composition of trust values for each individual software component (or service) used in the creation of that software system and their interaction patterns. This paper therefore presents the different composition patterns, and the common associations between various quality-of-service (QoS) properties of the composed system for the identified composition patterns. It also presents composition rules for deriving systemic trust values for each composition pattern. Lastly, results from applying the composition patterns to a case study show our trust composition model can predict trust of a composed system with 55% -- 70% uncertainty that increases with system complexity.
