Re: [Pidloc] draft-kjsun-ipwave-id-loc-separation

[<[e-mail]>]

Hi KJ,
thanks for your detailed information – and sorry for my delayed reply!
I agree that in the vehicular case it is not so much the (static) location privacy which could be exhibited, but a movement tracking privacy as mentioned also in Eriks draft https://www.ietf.org/archive/id/draft-nordmark-id-loc-privacy-00.txt.
Especially on highways with kind of predictable movement also a simple change of ID could  allow for derivation of a prior ID and mapping of all the modified ones – which may in the end even resolve the modification mechanism.
Do you think this is worth including in the planned use case based requirements analysis?
Thanks!
Kind regards
Dirk

Hello Behcet,

Thanks for giving me opportunity to introduce my draft "Considerations for ID/Location Separation Protocols in IP-based Vehicular Networks"
https://datatracker.ietf.org/doc/draft-kjsun-ipwave-id-loc-separation/

Purpose of this draft is to analyze applicability of ID/LOC protocols into vehicular network discussed in IPWAVE WG.

I considered LISP and ILNP as candidates protocols, and make use case based on vehicular network architecture described in IPWAVE PS doc (draft-ietf-ipwave-vehicular-networking)

In the Gap Analysis, I tried to follow issues described in PS doc, for each issue I referred d related ietf docs as possible solution.

Privacy issues in IPWAVE environment are well-described in PS doc. In that draft, they mentioned that tracking prevention should be supported with not only E2E continuity but also confidentiality. In my opinion, ID/LOC protocol may solve this problem easier since that ID information is not strongly bound to its location.

Honestly, I still have no idea for that and privacy issues were out of my interests. So, pidloc work could be helpful to analyze privacy issue and make solution for that.

I will more read related privacy documents and try to figure out for vehicular network use case. All comments and co-operations are welcome.

Regards,

KJ

Hello Gomjae,

Today, we had a Webex session with Dirk and discussed about your draft
draft-kjsun-ipwave-id-loc-separation



in this draft you introduced architectures for the use of IDLOC protocols in

vehicular networks.

We consider this one of the significant use cases in our pidloc activity.

We know you attended pidloc side meeting in Prague last week, thanks for that.



We would appreciate if you could introduce your draft to the list shortly in

your reply?



Also any ideas on the privacy issues that arise in the vehicular networking

from the use IDLOC protocols?



Regards,



Behcet & Dirk
