Deploy360@IETF91, Day 2: UTA, DPRIVE, BGP in ARNP, 6LO and IOT, DNSOP

IETF 91 mic lineFor us at Deploy360, Day 2 of IETF 91 brings a heavy focus on DNSSEC and DNS security in general with both DNSOP and DPRIVE meeting. Today also brings one of the key working groups (UTA) related to our “TLS in Applications” topic area.  There is a key WG meeting related to using  IPv6 in “resource-constrained” environments such as the “Internet of Things” (IoT) … and a presentation in the Internet Research Task Force (IRTF) about BGP security and the RPKI.

These are, of course, only a very small fraction of the many different working groups meeting at IETF 91 today – but these are the ones that line up with the topics we write about here at Deploy360.

Read on for more information…


NOTE: If you are not in Honolulu but would like to follow along, please view the remote participation page for ways you can listen in and participate.  In particular, at this IETF meeting all the sessions will have Meetecho coverage so you can listen, watch and chat through that web interface.  All agenda times are in HST, which is UTC-10 (and five hours earlier than US Eastern time for those in the US). I suggest using the “tools-style” agenda as it has easy links to the chat room, Meetecho and other documents for each session.


In the morning 9:00-11:30 block we once again will be splitting ourselves across multiple working groups.  In Coral 2 will be the “Using TLS in Applications” (UTA) working group looking at how to increase the usage of TLS across applications.  The UTA WG is a key part of the overall work of the IETF in strengthening the Internet against pervasive monitoring and should be quite a well-attended session.  The UTA agenda includes multiple drafts related to TLS and email, a discussion of a proposal around “token binding” and what should be an involved discussion about the TLS “fallback dance”, i.e. what should happen when a TLS connection cannot be made at the requested level of security?

On the topic of UTA, I’ll note that one of the groups main documents, draft-ietf-uta-tls-bcp, a best practice document on “Recommendations for Secure Use of TLS and DTLS“, has a new version out that incorporates all of the feedback received to date.  This document should soon be at the point where it will enter the publication queue.

Meanwhile, over in the Kahili room the 6LO WG will be talking about using IPv6 in “resource-constrained” and low power environments. The work here is important for sensor/device networks and other similar “Internet of Things” (IoT) implementations.   Among the 6LO agenda items are a discussion of using IPv6 in near field communications (NFC) and what should be quite an interesting discussion around the challenges of using different types of privacy-related IPv6 addresses in a constrained environment.

Simultaneously over in Coral 4 will be the open meeting of the Internet Research Task Force (IRTF) and of particular interest will be the presentation by one of the winners of the Applied Networking Research Prize (ANRP) that is focused on BGP security and the Resource Public Key Infrastructure (RPKI).  As the IRTF open meeting agenda lists the abstract:

The RPKI (RFC 6480) is a new security infrastructure that relies on trusted authorities to prevent attacks on interdomain routing. The standard threat model for the RPKI supposes that authorities are trusted and routing is under attack. This talk discusses risks that arise when this threat model is flipped: when RPKI authorities are faulty, misconfigured, compromised, or compelled (e.g. by governments) to take certain actions. We also survey mechanisms that can increase transparency when RPKI authorities misbehave.

The slides for the presentation are online and look quite intriguing!

After that we’ll be spending our lunch time at the “ISOC@IETF” briefing panel that is focused this time on the topic of “Is Identity an Internet Building Block?”  While not directly related to our work here at Deploy360 we’re quite interested in the topic.  I will also be directly involved as I’ll be producing the live video stream / webcast of the event.  You can join in and watch directly starting at 11:45 am HST (UTC-10). It should be an excellent panel discussion!

As I described in my Rough Guide post about DNSSEC, the 13:00-15:00 block brings the first meeting of the new DPRIVE working group that is chartered to develop “mechanisms to provide confidentiality to DNS transactions, to address concerns surrounding pervasive monitoring.”  The DPRIVE agenda shows the various documents under discussion – there are some very passionate views on very different perspectives… expect this session to have some vigorous discussion!

In the last 15:20-17:20 meeting block of the day we’ll focus on the DNS Operations (DNSOP) Working Group where the major DNSSEC-related document under discussion will be Jason Livingood’s draft-livingood-dnsop-negative-trust-anchors that has generated a substantial bit of discussion on the dnsop mailing list.  The DNSOP agenda contains a number of other topics of interest, including a couple added since the time I wrote about DNS for the Rough Guide.  The discussion about root servers running on loopback addresses should be interesting… and Brian Dickson (now employed by Twitter instead of Verisign) is bringing some intriguing new ideas about a DNS gateway using JSON and HTTP.

After all of that, they’ll let us out of the large windowless rooms (granted, in the dark of evening) for the week’s Social event that will apparently be a Hawaiian Luau.  After all the time inside it will be a pleasure to end the day in casual conversations outside. Please do look to find us and say hello… and if you are not here in Honolulu, please do join in remotely and help us make the Internet work better!
