Context Based Access Control in Pervasive Environments

As current trends show, the Semantic Web is the future interaction environment used in data exchange and integration among homogenous applications. This trend raises new challenges in security models used for access control, and the only acceptable model is to take into account the semantic relations of the interacting entities. In this article we present the access control module used by the Mobile services framework presented in our previous paper: "Web services applied to mobile environments". Finally we present results obtained in the implementation of this module and our conclusions.
