Abstract [en]

In emergency situations such as natural disasters the emergency personell should be able to establish communication fast and reliably. Depending on the nature of the disaster one cannot rely on existing communication infrastructure, or access to centralized administration. Additionally the established communication needs authentication in order to handle access control so only trusted parties can partake. A suitable medium for such communication is wireless ad hoc networks, but their flat structure make authentication a very challenging task. In this thesis a system design for an ad hoc routing protocol combined with access control is proposed, and implemented extending a popular routing protocol called BATMAN. The proposed authentication scheme relies on special public key certificates called proxy certificates, and combined with a neighbor trust mechanism both authentication and access control are managed in a secure manner. Tests using mobile nodes running this implementation shows that the performance of the proposed design is comparable to the original routing protocol (BATMAN) used, and that the authentication process is manageable even for mobile ad hoc networks.
