Last Call Review of draft-kuegler-ipsecme-pace-ikev2-
review-kuegler-ipsecme-pace-ikev2-secdir-lc-hanna-2011-04-14-00

I have reviewed this document as part of the security directorate's
ongoing effort to review all IETF documents being processed by the
IESG. These comments were written primarily for the benefit of the
security area directors. Document editors and WG chairs should treat
these comments just like any other last call comments.

This document defines a password authentication protocol for IKEv2
based on PACE (Password Authenticated Connection Establishment).

I am neither a cryptographer nor an expert on IPsec or IKEv2.
Given these limitations, I will say that I found the Security
Considerations section of the document to be thorough. All of
the security issues that I could come up with and more were
addressed in a credible manner. Overall, the document is clear
and well-written. Personally, I do not have any concerns with
this document becoming an RFC. However, it might be wise to
wise to have a cryptographer or expert in authentication protocols
provide an independent review of the document, if that has not
already been done. If it has been done, I have no concerns.

Thanks,

Steve Hanna
