Abstract : Service-oriented Computing (SOC) has appeared recently as a new software engineering paradigm. The very purpose of this reuse-based approach is to build applications through the late composition of independent software elements, called services, which are made available at run-time by internal or external providers. SOC brings properties of major interest. First, it supports rapid application development. Using existing, already tested, services is likely to reduce the time needed to build up an application and the overall quality of this application. SOC also improves software flexibility through late binding. A service to be used by an application is chosen at the last moment, based on its actual availability and on its properties at that moment. The service orientation has also to face thorny problems, as in any reuse-based approach. In this work, we focus on two major issues: the integration of heterogeneous service-oriented technologies and the management of security aspects when invoking a service. Security is actually a major concern to SOC practitioners. SOC technologies have allowed companies to expose applications, internally and externally, and, for that reason are heavily used. However, in some distributed environments, software services and process engines can be alarmingly vulnerable. Service-based processes can expose organizations to a considerable amount of security risk and dependability degradation. We propose to use a model-driven approach for solving this problem. During system design, paradigms such as abstraction, separation of concerns and language definition are used to define a model of the service composition with security properties. This model is transformed into an execution model. We present a generative environment applying these principles for service composition. This environment has been built as part of the SODA European project and validated on several industrial use cases.
