Title : Security Considerations for RFC5011 Publishers
Authors : Wes Hardaker
Warren Kumari
Filename :

Pages : 14

Abstract:
This document extends the RFC5011 rollover strategy with timing
advice that must be followed in order to maintain security.
Specifically, this document describes the math behind the minimum
time-length that a DNS zone publisher must wait before signing
exclusively with recently added DNSKEYs. It contains much math and
complicated equations, but the summary is that the key rollover /
revocation time is much longer than intuition would suggest. If you
are not both publishing a DNSSEC trust anchor, and using RFC5011 to
update that trust anchor, you probably don't need to read this
document.
This document also describes the minimum time-length that a DNS zone
publisher must wait after publishing a revoked DNSKEY before assuming
that all active RFC5011 resolvers should have seen the revocation-
marked key and removed it from their list of trust anchors.
