Abstract

A Multi-Organization Environment is composed of several players that depend on each other for resources and services. In order to manage the security of the exchange process the authors introduce the concept of trust. The authors show how adding this aspect of the cooperative work. In particular, the authors provide a framework where the concepts of trust requirement and trust evaluation play important roles for defining trust vectors. These vectors evaluate a set of requirements, under some conditions, and provide a degree of confidence. In the authors' framework they consider two different types of vectors. On the one hand a vector that relates a user to an organization and on the other hand a vector that links two organizations. Different simulations are presented in this paper in order to show this approach. Moreover, the authors show how these vectors are evaluated and shared among the different organizations. Finally, the authors propose a possible architecture to explain how to integrate their trust module in MOE in order to enhance the security.
