Video: Emil Ivov about Jitsi, a VoIP softphone supporting IPv6 and DNSSEC

jitsi.jpgThe Jitsi audio/video softphone and messaging client supports both IPv6 and DNSSEC.  How did it get started with IPv6 support?  Why did it add DNSSEC? What value does DNSSEC add to VoIP and IP communications?   We first wrote about Jitsi’s DNSSEC support almost a year ago, but earlier this month at IETF86 I had a chance to sit down with Jitsi project lead Emil Ivov and ask him these questions and much more:

Jitsi is available for Windows, Mac OS X and Linux from:  http://jitsi.org/  It used to be called the “SIP Communicator” but when they added support for XMPP (Jabber) and XMPP/Jingle back in 2011 they changed the name to be Jitsi.

Given my own personal interest in VoIP / IP communications, I’m planning to write a bit more about Jitsi as I get a chance to do so.  If any of you use Jitsi and create any screencasts about its IPv6 or DNSSEC support – or write up any articles about those capabilities – please do let us know as I’d like to include more on our site about this great project.

Video: What are “Negative Trust Anchors” for DNSSEC?

What are “negative trust anchors” for DNSSEC? What function do they perform? Why do we need them? In this video, Dan York interviews Jason Livingood about his Internet-Draft on this topic and answers these and other questions:

The Internet-Draft can be found at:

http://tools.ietf.org/html/draft-livingood-negative-trust-anchors

Jason and his co-author are seeking comment and would appreciate feedback from people about this draft – does it make sense? Would you use it? Do you see any ways to improve their ideas? Their email addresses can be found at the end of the document and they are definitely open to feedback.

Jason Livingood is Vice President of Internet & Communications Engineering at Comcast and is one of the co-authors of this draft.

More information about DNSSEC can be found at the Deploy360 website at:

This interview was recorded at the 86th meeting of the Internet Engineering Task Force (IETF) in March 2013 in Orlando, Florida, USA.

Slides: DANE, the next big thing after DNSSEC

What is the DANE protocol all about? How does it protect Internet communication? How does it relate to SSL/TLS certificates? What is wrong with the Web’s public key infrastructure (PKI), anyway?

At a recent cybersecurity conference in the Netherlands, Marco Davids of SIDN gave a presentation titled, “DANE, the next big thing after DNSSEC,” that covers these and other questions – and does so with a good degree of detail. His slides are available:

DANE presentation by SIDN

We, too, agree that DANE has a great potential to make the Internet much more secure by marrying the strong integrity protection of DNSSEC with the confidentiality of SSL/TLS certificates. We would encourage you to look at our DANE resources and start looking at what you can do today!

Video: The Mobile Business Case for IPv6

At the World IPv6 Congress in Paris last week, Cisco’s Mark Townsley gave this great interview about the business case for IPv6 in mobile networks:

It was great to hear his mention that Verizon is sending 30% of its traffic to Google over IPv6 as well as the mention of IPv6 growth on other mobile networks.

Hat tip to Cisco’s blog, where we first spotted mention of this video.

Google Clarifies DNSSEC Support – Opt In Now, Full Validation Coming Soon

Google logoAfter Google’s announcement earlier this week of DNSSEC validation support in their Public DNS service, there was some concern and discussion in various DNSSEC mailing lists about the fact that DNSSEC validation was not being performed by default and required a client to request validation.  Folks at Google clarified that this was just part of their initial rollout and that providing full validation is in their plans.

They have now also updated their FAQ about DNSSEC support in Google Public DNS and most importantly updated these two questions (my emphasis added):

Does Google Public DNS support the DNSSEC protocol?
Yes. Google Public DNS is a validating, security-aware resolver. Currently this is an opt-in feature: for queries coming from clients requesting validation (the AD and/or DO flag is set), Google Public DNS verifies that response records are correctly authenticated. Validation by default (i.e. for all queries) will be enabled soon.

Which client resolvers currently enable DNSSEC?
Unfortunately, most standard client stub resolvers do not enable full DNSSEC checking and cannot be easily reconfigured to do so. We have decided to make our initial launch only cover resolvers that explicitly ask for DNSSEC checking so that we become aware of any problems before exposing our users to possible large-scale DNS failures due to DNSSEC misconfigurations or outages. Once we are happy that we can safely enable DNSSEC for all users except those who explicitly opt out, we will do so.

It’s great to see Google responding to questions and adding these clarifications – and from the point of view of advocacy for DNSSEC deployment, it is great to have Google out there endorsing and promoting DNSSEC as a way to increase Internet security.

(And you can easily get started with DNSSEC if you haven’t already.)

For those of you who enjoy listening to audio, I recorded some audio commentary on our SoundCloud channel about why I view this news from Google as incredibly important:
