IETF 102, Day 3: DNSSEC, DPRIVE & IoT

Kevin Meynell
By Kevin MeynellManager, Technical and Operational Engagements

This week is IETF 102 in Montreal, Canada, and we’re bringing you daily blog posts highlighting the topics of interest to us in the ISOC Internet Technology Team. And today’s topics include DNS Security & Privacy, along with more IPv6 and IoT.

The first DNSOP session will start at 09.30 EDT/UTC-4, and will continue on Thursday evening. Topics of interest include a draft on Algorithm Implementation Requirements and Usage Guidance for DNSSEC, which updates current algorithm implementation requirements and usage guidance for DNSSEC (obsoleting RFC 6944). Another draft on Multi Provider DNSSEC models describes how to deploy DNSSEC in environments where multiple DNS providers are in use, whilst Delegation_Only DNSKEY flag introduces a new flag for DNSSEC keys that can address a potential attack.


NOTE: If you are unable to attend IETF 102 in person, there are multiple ways to participate remotely.


Alternatively, the relatively new working group SUIT will also be meeting at the same time. Vulnerabilities in Internet of Things (IoT) devices have raised the need for secure firmware updates that are also suitable for a constrained environments, and this group aims to develop an interoperable update mechanism. There are three drafts up for discussion, including the description of the firmware update architecture, a specification for the firmware update metadata model or manifest, as well a specification for the firmware manifest format. The next steps will also be discussed.

In the first afternoon session starting at 13.30 EDT/UTC-4, there’s a choice of DPRIVE or 6TiSCH.

DPRIVE will kick off with an analysis of RIPE Atlas probe data relating to DNS Privacy, before discussing some recommendations for DNS Privacy Service Operators. There’s also some new work on Oblivious DNS that introduces an additional layer of obfuscation between clients and their queries, and there will be some discussion about how to add privacy to the communication between recursive resolvers and authoritative DNS servers. The latter is beyond the scope of the current Working Group charter and so the group will consider whether to ask to expand their mandate.

6TiSCH has a busy agenda with the 6top protocol that enables distributed scheduling being targeted for an IETF Last Call, whilst the IESG feedback on the security functionality will be discussed. Two other drafts are aiming for Working Group adoption including a description of a scheduling function that defines the behavior of a node when joining a network and a mechanism for carrying important information in infrequent network broadcasts. Another new draft defines a secure joining mechanism for enrolling devices into an 802.15.4 TSG network using 6TiSCH signalling methods.

In the second afternoon session starting at 15.20 EDT/UTC-4, Homenet will continue to discuss the Homenet profile of the Babel routing protocol. There are also two updated drafts on the agenda, relating to third party provisioning of naming services for home networks and defining DHCPv6 options so that naming services can be outsourced.

Rounding off the day is the IETF Plenary starting at 17.10 EDT/UTC-4.
