The original presentation, written by Alan Clegg and as published on ISC's website, was DNSSEC in 6 minutes.
That article, along with a more recent presentation (taking advantage of improvements in automation and key management) are both made available here in PDF form.
The ISC DLV server is no longer active because it is no longer needed. See our blog post on the topic: DLV Replaced with Signed Empty Zone.
Other improvements have been made to ISC's DNSSEC implementation since these presentations were written, so although they cover the basic principles of DNSSEC very well, there are newer and better management tools available.
