Service oriented environments are computer network systems that are highly dynamic and change with time. Entities in such environments have different security needs from services. Management of security information in dynamic environments with multiple entities, each with its own changing needs, is a complex task. The complexity mainly arises from a lack of trust to security information collected from entities and services. Therefore, the trust assessment about services, which is a crucial task, depends on the propagation of security information. In this paper, a new model of security information flow over entities is proposed for trust computation about services. The model is presented together with a simple scenario to clarify the proposed model.
