BPSec Default Security Contexts
draft-ietf-dtn-bpsec-interop-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.
