Abstract

Service composition and related technologies have provided favorable means for building complex Web software systems. It may span multiple organizational units requires particular considerations on trustworthy issues. However, the distributive and heterogeneous characteristics of services make it hard to guarantee trustworthiness of service composition. This paper presents a method for analyzing dynamic trustworthy service composition according to the characteristics and requirements of service composition. Petri nets are used to precisely describe the composition process in order to describe the logic relation between different components. Based on this, the concept of trust matrix is given to represent the relationships between states. A trustworthy service composition strategy and its enforcement method are proposed. A case study of Travel Service demonstrates the feasibility of proposed method.
