Which of the following is an example of over-the-air (OTA) provisioning in digital rights management?

Over-the-air (OTA) provisioning, especially in the context of digital rights management (DRM), frequently involves securely transmitting cryptographic keys or shared secrets to a device to establish or rebuild a trust relationship. This secure key exchange allows for the reliable delivery and management of digital content and associated rights, ensuring only authorized devices can access it.

Using software to meet deployment goals is a broad statement and not specific to the secure trust provisioning aspect of OTA in DRM. It describes a general objective rather than a mechanism for establishing trust.

Use of concealment to avoid tampering attacks is a security tactic (security through obscurity) but is not a direct method of OTA provisioning for trust establishment. It does not explain how a device gains initial trust or is re-provisioned.

Using device properties for unique identification is a method for distinguishing devices, not the process of securely provisioning or re-establishing trust over-the-air. Identification precedes or complements provisioning, but is not the provisioning itself.
