4. LEADING COLLABORATION
IN THE ARM ECOSYSTEM
Trust
is not
security

5. LEADING COLLABORATION
IN THE ARM ECOSYSTEM
Key trust enabler: Confidential computing
● Arm has extensive experience with TrustZone and OPTEE
○ Mobile handset non-brickable device
○ Set top box: digital rights verification
● Usages
○ Non repudiable logs
○ Attestations (software or information)
○ Obfuscation (regulatory compliance…)
○ Key management: TPM as a Service
● New programming paradigm: OpenEnclave
○ Multi-architecture
○ Simple to have per service confidential part (Netflix)
○ Arm: available before OS boot stage

IN THE ARM ECOSYSTEM
Authentication
is not
authorization

7. LEADING COLLABORATION
IN THE ARM ECOSYSTEM
Building trust
● Problems to solve
○ Trust hardware
○ Trust measurement up to cloud
○ Authentication = authorization : car key dupplication
○ Authentication and authorization by same entity: 2 factor
● Solution elements
○ Device onboarding:
○ Sensor/device OPTEE/OpenEnclave/TPM
○ OPTEE/OpenEnclave, block chain?
○ Device authentication, cloud authorization

8. LEADING COLLABORATION
IN THE ARM ECOSYSTEM
Call to action
● Application level modeling: todo
● Edge stack APIs: todo
● Middleware: todo / in progress
● Hardware support: OK
