Highly dynamic ad hoc radio networks are the key technology for future military and crisis management operations but also raise additional challenges for secure communication between networks with higher security levels attached to mobile nodes. The authors propose an efficient solution to the currently not satisfactorily handled task of providing a mapping between node identifiers in the radio network and reachable addresses in the attached secure networks while separating security domains and supporting the nodes' ability to leave and join different radio networks, for example IP-based ad hoc or non-IP radio links.
