Minimal Security rekeying mechanism for 6TiSCH
draft-richardson-6tisch-minimal-rekey-00
Abstract
This draft describes a mechanism to rekey the networks used by 6TISCH
nodes. It leverages the security association created during an
enrollment protocol. The rekey mechanism permits incremental
deployment of new sets of keys, followed by a rollover to a new key.

1. Introduction
2. Terminology
The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
document are to be interpreted as described in [RFC2119]. These
words may also appear in this document in lowercase, absent their
normative meanings.
The reader is expected to be familiar with the terms and concepts
defined in [I-D.ietf-6tisch-terminology], [RFC7252],
[I-D.ietf-core-object-security], and
[I-D.ietf-anima-bootstrapping-keyinfra].
3. An approach to rekeying
TBD
4. A YANG model for keys
It optionally also contains an IEEE 802.15.4 short-address
[IEEE8021542015] assigned to pledge by JRC.
5. Rekey of master connection
TBD

6. Privacy Considerations
TBD
7. Security Considerations
TBD
8. IANA Considerations
This document allocates a SID number for the YANG model. There is no
IANA action required for this document.
