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. Surprisingly for a non protocol draft, this one actually is almost completely security requirements. Unfortunately I find it rather hard to tell if the security architecture meets the security goals because they are not separated from each other. I think the document should have a section stating the security goals or reference another document that states them. Presumably these are all derived from the Nomcom RFC. The document specifies creation of a public key but not the algorithm or strength. Given that this is an RFP, I think it would be appropriate to completely and uniquely specify the cipher suite to be supported. -- Website: http://hallambaker.com/
