"Allowing first responders to access emergency-support information for which they are normally not authorized can save lives and property. A trusted emergency management solution was developed at the Naval Postgraduate School to provide transient access to sensitive information during an emergency. This document provides a high-level design analysis for performing distributed emergency signaling for this system over a tactical IP [Internet Protocol] network. We describe how the protocol supports the emergency management concept of operations. The document specifies requirements pertaining to emergency signaling and includes an analysis that describes the system response to all possible emergency state transitions. We also review various communication protocols and evaluate their merits with respect to their suitability for use on emergency networks. Detailed design analysis supports the commencement of an emergency management implementation phase."
