Description
-----------

The *scp03* command calls into a Trusted Application executing in a
Trusted Execution Environment to enable (if present) the Secure

This protocol encrypts all the communication between the processor and
the secure element using a set of pre-defined keys. These keys can be
rotated (provisioned) using the *provision* request.
