Abstract
Ad hoc networks for first responders in emergency situations have some unique characteristics that differ from general ad hoc networks, since it is desirable to restrict who can participate in the network without relying on a predeployed infrastructure. In this paper we present security requirements elicited for a first responder mobile ad hoc network in the OASIS project. The requirements have been identified in a structured manner, based on identification of objectives, assets and threats towards these assets.
