At the DNSSEC Workshop earlier this month at ICANN 47 in South Africa, I gave an introductory tutorial about the DANE protocol and how it can be used to secure Internet communication such as that through a web browser. I explained how DANE works, outlined some use cases and provided a series of links for people to learn more. The slides are now online:
I did record a video of the presentation and hope to get that uploaded in the next couple of (busy!) weeks.
More information about DANE can of course be found on our page about the DANE protocol.
