                        draft-ietf-dtn-bpsec-00

Abstract

   This document defines a security protocol providing data
   authentication, integrity, and confidentiality services for the
   Bundle Protocol.  Capabilities are provided to protect blocks in a
   bundle along a single path through a network.
