Alissa Cooper has entered the following ballot position for draft-ietf-6lo-nfc-13: Discuss When responding, please keep the subject line intact and reply to all email addresses included in the To and CC lines. (Feel free to cut this introductory paragraph, however.) Please refer to https://www.ietf.org/iesg/statement/discuss-criteria.html for more information about IESG DISCUSS and COMMENT positions. The document, along with other ballot positions, can be found here: https://datatracker.ietf.org/doc/draft-ietf-6lo-nfc/ ---------------------------------------------------------------------- DISCUSS: ---------------------------------------------------------------------- I support Benjamin's DISCUSS point about large antennas. RFC 2119 specifies the keywords "RECOMMENDED" and "NOT RECOMMENDED." This document uses these in verb form ("RECOMMEND" and "NOT RECOMMEND"). Please change these instances so that the actual 2119 keywords are used. = Section 4.8 = I think the Gen-ART reviewer's question about fragmentation is unresolved. How is interoperability achieved if some nodes implement MIUX and not FAR, and some nodes implement FAR and not MIUX? It seems as though IPv6-over-NFC needs to be restricted to nodes that support one or the other (presumably MIUX). = Section 5.1 and 7 = Per the Gen-ART review, one of these sections needs to say something about how connecting to the Internet potentially changes the threat model for devices that were perhaps not originally envisioned to connect to the Internet. ---------------------------------------------------------------------- COMMENT: ---------------------------------------------------------------------- = General = I agree with Benjamin that the marketing-type language in the document should be removed. I wonder about the claims of security based on proximity in this document. Presumably attacks in which users are induced to tap their device against another node or terminal which has been compromised by an attacker are becoming more common as NFC becomes more common; adding IPV6 connectivity to the terminal stack surely broadens the potential damage done in such a case. This seems worth noting. = Section 1 = OLD It has been used in devices such as mobile phones, running Android operating system, named with a feature called "Android Beam". In addition, it is expected for the other mobile phones, running the other operating systems (e.g., iOS, etc.) to be equipped with NFC technology in the near future. NEW At the time of this writing, it had been used in devices such as mobile phones, running Android operating system, named with a feature called "Android Beam". It was expected for the other mobile phones, running the other operating systems (e.g., iOS, etc.) to be equipped with NFC technology in the near future. = Section 4.5 = Per the Gen-ART review, the use of the term "meet" is confusing in this section. Please re-phrase.
