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. This draft proposes an experimental extension to the LoST protocol to add additional information to the data being exchanged. While the LoST protocol exchanges raise significant privacy and confidentiality concerns, it does not appear to me that the additional data proposed raises different or additional concerns. It is thus appropriate for this document to refer back to the original protocol document which in turn considers the privacy issues in considerable detail. -- Website: http://hallambaker.com/
