Dear all,
as announced already last year we plan to have a side meeting in Prague next month.
As soon as the room situation is clear and we have agreed on an agenda we let you know.
Please feel free to share your ideas on this here!
Thanks!
Kind regards
Dirk

Dear all
Last week we had the call announced and I would like to let you know what we talked about.
Presumably the major outcome is that we should focus more on general topics of security and privacy assurance in Id-Location mapping systems – especially for new applications raising more critical scaling issues than we currently assume.

Please have a look and comment - for clarification or in case of differing views!
Thanks and best regards
Dirk (also on behalf of Behcet)
Thanks also to Roland for helping with his memory ;-)

participants in the webex call on Thur Dec 13, 5 pm UTC:
Roland Schott, Dirk v. Hugo (DTAG), Tom Herbert (Quantonium), Behcet Sarikaya (Denpel Informatique)

Behcet presented the slides on ‘Privacy Issues in Identifier Locator Separation Protocols’
Tom pointed out that the use cases 1/3 just require a secure mapping system to not expose identities and locations to outside world, while UC2 on geolocation is a handled on application layer – simply don’t expose location!
Main problem he sees is the correlation between IP addresses (same prefixes of different flows from a device) and an identity. Identity correlation  problem needs work on back-end, not on protocol.
Id/location security system is the main problem to work on
Tom mentions a draft on the mapping system he is currently writing – not referring to 3GPP.
Industrial IoT may need optimized Routing to nearest edge cloud for low latency (anchored routing). Here handling of privacy in combination with scale of routing at the Edge (Routing System) is worth working on.
Id/Loc split protocols and ILA (as well as GUE and GTP) are only examples/technologies and use cases (not actually required/to be focused on) for (same) bigger privacy problem to solve – that would attract people to work on. ILA is only an encapsulation format; in case 3GPP wants to keep GTP, although it has drawbacks, this might be also an option
SEC area does handle a variety of issues – but INT area is related to IP addresses and mapping systems (Tom prefers latter AD)
Toms advice: to address the bigger problem – independent of technology.
It’s all about Routing and correlation between IP address and identity.
People will try to meet in Prague for a side meeting.
