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 mandatory set of security
contexts.
This document defines two security contexts (one for integrity
services and one for confidentiality services) for populating BPSec
Block Integrity Blocks (BIBs) and Block Confidentiality Blocks
(BCBs).
The intent of these security context definitions is to provide a
mechanism for interoperability testing. There is no claim that these
contexts are suitable for operational deployment in any particular
networking scenario. Further, there is no requirement that these
contexts be used in any operational network deployments.
