[ksk-rollover] ICANN board meeting result and the Current status of KSK-Rollover

[Eric Osterweil]

I think the setting of this discussion is missing some key elements: the DNS Root KSK is a global root of trust.  The extent to which we build on that is the extent to which software will need for this key to be well known, knowable, and learnable.  As the frequency of its rollover increases, so too does the probability that software will have out of date keys (especially I the context of hyperlocal roots).  If you factor DANE in, that root has even more importance to end-user perception.  I think it needs to be a top priority to ensure that DNS Relying Party (RP) software knows how to maintain the current key, keep up with rollovers, and re-bootstrap when it loses the correct key (a failure mode that software absolutely will experience).  As of now, I don’t think we have more than a few nascent ideas about how to handle this.

Just my 0.02,

Eric
