Device Assignment (DA) is the method which allows a device to be uniquely assigned to an individual Realm, and to allow the Realm to attest the device before granting it access to the Realm’s contents. This session will cover the overview of Device assignment feature, the high level design aspects in RMM and how RMM manages the lifecycle of assigned devices to the Realm using TDISP (TEE Device Interface Security Protocol). We will finally cover the current status of work and future plans.
