Mime-Version: 1.0 Sender: owner-cryptography@c2.net (This is a note I posted on the PKIX (Public Key Infrastructure) mailing list. I would be interested in comments on this document -- the draft is <ftp://ds.internic.net/internet-drafts/draft-ietf-pkix-ipki3cmp-02.txt>
-----BEGIN PGP SIGNED MESSAGE-----
It seems to me that PKIX Part 3, section 2.2.2.1 "Centralised scheme" requires that a conformant implementation support the capability of generating the private key at the CA. This means that a conformant implementation essentially is required to implement key recovery.
I do not think that this conforms to IETF practice and I certainly do not want to require CA implementations to support this capability. If for some reason someone wants to implement this I can see it being an optional feature but I do not think it is an acceptable mandatory requirement.
