+
+Description
+-----------
+
+The *scp03* command calls into a Trusted Application executing in a
+Trusted Execution Environment to enable (if present) the Secure
+Channel Protocol 03 stablished between the processor and the secure
+element.
+
+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.
