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
