[Mip6] [issue87] Comment by Sam Hartman on I-D draft-ietf-mip6-location-privacy-ps

[admin <tracker-mip6 at mip4.org>]

New submission from admin <roundup-admin at mip4.org>:

Discuss:
>Even when the binding between a user
>    identifier and the Home Address is unavailable, freely available
>    tools on the Internet can map the Home Address to the owner of the
>    Home Prefix, which can reveal that a user from a particular ISP
>    has roamed.  

If the above is in scope, then the discussion of the problem is
incomplete.  Sending an esp packet from ISP B to one of ISP A's HAs
really discloses as much information as the above paragraph implies.


I think this draft does a bad job of explaining its scope and
convincing me that the problem being solved is important to solve.
For example why are IIDs out of scope?  Why is the ESP corrilation I
discuss above out of scope?  If those attacks are out of scope, what
real benefit remains to hiding roaming from onlookers?


Finally, I do not understand what work is left to do in this space.
This draft describes the problem and points out that encrypted tunnels
and not using RO are a solution.  What additional problems are being
solved beyond that?  What work is there for the IETF to do in this
space?  A problem statement should clearly articulate these points.

Comment:
I agree with Lisa that this document is unclear--not quite
to the point of earning a discuss for lack of clarity--but unclear
enough that if you haven't been reading mip6 documents for a while,
you won't understand what is going on.  It conflates profiling and
location privacy,  and describes more than supports its conclusions.
