                    draft-burleigh-dtnwg-dtka-00.txt

Abstract

   Delay-Tolerant Key Administration (DTKA) is a system of public-key
   management protocols intended for use in Delay Tolerant Networking
   (DTN).  This document outlines a DTKA proposal for space-based
   communications, which are characterized by long communication delays
   and planned communication contacts.
