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 cipher suite results and associated meta-data, but does not
   define a common set of supported cipher suites.  This document
   extends BPSec and defines an integrity cipher suite and a
   confidentiality cipher suite suitable for populating BPSec Block
   Integrity Blocks (BIBs) and Block Confidentiality Blocks (BCBs),
   respectively.

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

   The intent of these cipher suite definitions is to provide a
   mechanism for interoperability testing.  There is no claim that these
   cipher suites are suitable for operational deployment in any
   particular networking scenario.  Further, there is no requirement
