1. Directions for Release 3 Group Name: SEC Source: Mihai.Moraru@neclab.eu, NEC Europe Ltd. Meeting Date: SEC22, 2016-03-18 Agenda Item: Discuss directions for R3 and possible WI

2. Features MAS SEC TST Resources, Flows, Semantics ARC, PRO, REQ ESData, ESPrim, ACPs, Roles, Dyn AuthZ, Distrib AuthZ Implementation

3. Covered in Rel1 and Rel2 Resources – Confidentiality, Integrity (ESData) – Authorization (dynamic, distributed) Flows – Confidentiality, Integrity (ESPrim) Entities – Authentication © 2014 oneM2M Partners 3

4. Centralized application design ADN MN IN Infrastructure domain Field domain ADN MN …… Centralized data processing by AE-IN Sensors generate data which is drained towards the infrastructure

5. Extend security support MAS SEC TST Virtual resources, Availability requirements Etc. ARC, PRO, REQ Secure environment, Change of ownership

6. Support more flexible designs Focus on existing requirements Processing on the M2M Gateway – Mobile scenarios, intermediate processing Data security at rest – Big Data repository, outsourcing

7. Processing on the M2M Gateway

8. Problems with centralized design ADN MN IN Infrastructure domain Field domain ADN MN …… Centralized data processing by AE-IN Congestion, latency, inefficient bandwidth usage Connectivity loss Car Broken link Device mobility

9. Processing on MN – automotive example Sensor ECU … Infrastructure Sensor Compute speed Broadcast speed Following vehicle Vehicle Verify

10. Processing on MN – automotive example … Communication inside the automobile Communication outside the automobile Vehicle ADN-AE ADN ADN-AE ADN ADN-AE ADN MN-AE MN2 MN-CSE MN-AE MN1 MN-CSE IN-AE IN IN-CSE Possible mapping to oneM2M Compute Verify

11. Processing on MN – automotive example Clarifications, open issues – Node registrations are not represented – Tbd: How MN1 discovers MN2 – Communication paths are logical, they show information flow. Tbd: exact retrieval mechanism (i.e.: request or notify) This is only one example where processing on the MN is needed in a secure way Discussions are welcome – Gathering support for a new WI
