Model-based security verification and testing for smart-cards

Model-Based Testing (MBT) is a widely used methodology for generating tests aiming to ensure that the system behaviour conforms to its specification. Recently, it has been successfully applied for testing certain security properties. However, for the success of this approach, it is an important prerequisite to consider the correctness of test models with respect to the given security property. In this paper we present an approach for smart-card specific security properties that permits to validate the system with MBT from test schemas. We combine this MBT approach with UMLsec security verification technique, by using UMLsec stereotypes to verify the model w.r.t. given security properties and gain more confidence in the model. We then define an automatic procedure to generate security test from the UMLsec model via so-called "test schemas". We validate this approach on a fragment of the Global Platform specification and report on available tool support.
