1.  Introduction

   The Bundle Protocol Security (BPSec) [I-D.ietf-dtn-bpsec]
   specification provides inter-bundle integrity and confidentiality
   features for networks deploying the Bundle Protocol (BP)
   [I-D.ietf-dtn-bpbis].  BPSec defines a set of BP extension blocks to
   carry security information produced under the auspices of some
   security context, but does not define a common set of these security
   contexts.

   This document defines two security contexts (one for integrity
   services and one for confidentiality services) suitable for
   populating BPSec Block Integrity Blocks (BIBs) and Block
   Confidentiality Blocks (BCBs).

   This purpose of the security contexts described in this document is
   twofold.  First, these contexts should be used to test the
   interoperability of BPSec implementations.  Second, this
   specification can serve as a template to be followed by other BPSec
   security context authors.

   The intent of these security context definitions is to provide a
   mechanism for interoperability testing.  There is no claim that these
