Calling time on DNSSEC part 2 of 2

In his regular monthly spot on PING, APNIC’s Chief Scientist Geoff Huston continues his examination of DNSSEC. In the first part of this two-part story, Geoff explored the problem space, with a review of the comparative failure of DNSSEC to be deployed by zone holders, and the lack of validation by the resolvers. This is visible to APNIC labs from carefully crafted DNS zones with validly and invalidly signed DNSSEC states, which are included in the Labs advertising method of user measurement.

This second episode offers some hope for the future. It reviews the changes which could be made to the DNS protocol, or use of existing aspects of DNS, to make DNSSEC safer to deploy. There is considerable benefit to having trust in names, especially as a "service" to Transport Layer Security (TLS) which is now ubiquitous worldwide in the web.
