This specification is work in progress and should be considered to be in a beta stage. There is ongoing work to implement this interface in Mbed TLS, which is the reference implementation of the PSA Cryptography API. At this stage, Arm does not expect major changes, but minor changes are expected based on experience from the first implementation and on external feedback.

If the driver has an [`"allocate_key"` entry point](#key-management-in-a-secure-element-with-storage), the core calls the `"allocate_key"` entry point with the same attributes on the same key buffer before calling the key creation entry point.
