Title : Parent's SIG over child's KEY
Author(s) : M. Gieben, T. Lindgreen
Filename : draft-ietf-dnsop-parent-sig-00.txt
Pages : 4
Date : 25-Jan-01
When dealing with large amounts of keys the procedures to update a zone and to sign a
zone need to be clearly defined and practically possible.
The current idea is to have the KEY RR and the parent's SIG to reside in the child's
zone and perhaps also in the parent's zone. We feel that this would lead to very
complicated procedures for large TLD's. We propose a alternative scheme in which the
parent zone stores the parent's signature over the child's key and also a copy of the
child's key itself.
The advantage of this proposal is that all signatures signed by a key are in the same
zone file as the producing key. This allows for a simple key rollover and resigning
mechanism. For large TLD's this is extremely important.
We further discuss the impact on a secure aware resolver/forwarder.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
