[secdir] draft-ietf-ipsecme-ikev2-null-auth-06 SECDIR review

[Donald Eastlake <[e-mail]>]

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 should be treated like other last call comments.

This draft provides a null authentication method and a null identity for
use in IPsec, specifically the Internet Key Exchange Protocol version 2
(IKEv2).

Overall this is an excellent draft and useful in countering pervasive
surveillance in IKEv2.

The Security Considerations section is quite thorough. I did notice one
small thing: Section 3.1 is labeled "Audit trail and peer identification".
But the content of that Security Considerations section is about not
trusting identification when null authentication is used. It seems to me
that a few words to the effect that some clear indication should be present
in audit/log trails when a purported identity has not been authentication
should  be included, as I expected them to be from the section heading.

Thanks,
Donald
