                    BPSec Default Security Contexts
                   draft-ietf-dtn-bpsec-default-sc-02

Abstract

   This document defines default integrity and confidentiality security
   contexts that may be used with the Bundle Protocol Security Protocol
   (BPSec) implementations.  These security contexts may be used for
   both testing the interoperability of BPSec implementations and for
   providing basic security operations when no other security contexts
   are defined or otherwise required for a network.
