Hi, 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. Still READY. The Security Considerations section appears to be adequate. I found no nits in the document that will be published. In the Implementation Section, which will be removed prior to publication, s/tenefit/benefit. Best regards, Chris
