During the Kantara Plenary Ingo gave an update on what the group is currently doing. I used the presentation that can be found at our web site: http://kantarainitiative.org/confluence/download/attachments/64389214/20140217_IDoT_WF2014seoul_v1.0.pdf?version=1&modificationDate=1393341197000&api=v2
Among the white spots, unsolved und unstandardized problems in IoT IdM we have discovered a ratherr urgent ones. Before it comes to authentication, communication or security Things have to find each other. We took the “Farming Example”:
Every morning the cabin-harvester meets other trucks. The harvester uses “serial no.”. Trucks use the IMEI of their GSM-module other use the License plate number. DNS does not work here. How these machines find each other’s IP-addresses when they use different identifier? There is an urgent need for something like “Object – DNS”.
Object Name Service
In order to design a DNS for Things or an Object Name Service we have to consider several technologies including the advantages / disadvantages / challenges etc:
- CS1 (incl. the step back of France because of Privacy Issues with Neustar)
- XRI as a syntax allowing for putting different name spaces in one string (now maintained in XDI)
- A static namespace like RFC 4350 (New Zealand URN) describing how to construct a namespace
- DNS – Why is DNS not sufficient for IoT
- “WhoIs” lookup
- IETF Web link according to RFC 5988
- Why is IPv6 alone not sufficient
- Is there a role for Ontologies
- Resolution/indirection (first step e.g. results in personal cloud / a second step accesses the personal cloud …incl access control)
Colin raised another important question we have to consider in such a system:
How to ensure that the identifier is unique?
Once we have an abstract model there should be a translation to low power protocols to IEEE ; for TCP/IP protocols to IETF
Action point:
We will assign sub-topics from above to persons in the group. (If you read this and you want to volunteer you are highly welcome ;-)
Governance model for IoT data
Ingo discussed a very basic model to govern data in the IoT.
Action point:
Ingo describes the “governance model for IoT data” in a more detailed way as a concept /document combined with slides and pictures. Then Ask for feedback in Kantara:
- Information Sharing Group (Remark: getting Feedback is not critical later on we have to check the implications of their RAND policy)
- User Managed Access Group
Terminology
When we write our papers we should re-use and check for terminology / concepts of other standard groups like:
- IETF
- IEEE
- ITU-T
- Cisco
- IBM
