Hello, 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. IMHO, the document is  ready. Although the document is fairly small, there is a good security section that seems to me to address all the important aspects. I don't have any comment. Cheers,    Vincent
