Thanks to everyone who has worked on this document.
I generally agree with Benjamin's discuss points, and in particular
agree with his comment that it's kind of hard to figure out how all
these pieces work together. I have an additional issue that is
somewhat related to some of the points he raised, but which is (I think)
not completely covered.
I'm really confused about what the purported privacy properties of
this protocol are. In section 4.3 (which I *think* talks about
globally- routable IP addresses, although this is a bit unclear), the
document says:
such an IID SHOULD guarantee a stable IPv6 address
because each data link connection is uniquely identified by the pair
of DSAP and SSAP included in the header of each LLC PDU in NFC
(Aside: this "should" is a simple statement of fact, not a described
behavior of the protocol, and so the use of RFC-2119-style all-caps
is not
appropriate.)
Agreed. I will fix it.
The presence of "a stable IPv6 address" inherently implies the
ability to track devices.
Agreed. I will change them with "a secured and stable IPv6 address".
This is ok?
I don't think this changes the issue. Your response below implies that the
address is stable only over very short periods of time, and that would
address my concern. If that's true, then the solution would be to add text
here that qualifies how long the address is stable (e.g.:
"...such an IID should guarantee a stable IPv6 address during the course
of a single connection, because...")
I got it. I will put the text. Thanks for your comment again.
Thanks! I'll clear my discuss once the new version is submitted.
