Provisioning Service Driven Interaction
3.6.10.2 XML Data Exchange: Secure Mode, No PIN
1. As step 1 start-up is described already in Section 3.5.1.2, "XML Data Exchange", only the
subsequent steps are demonstrated here.
2. As the device is configured to Secure Mode without PIN, the provisioning service sends a
request to switch to Secure Mode (bootstrapping) including certificates and secure-port
number.

3. Device responses to default provisioning server port and confirms that the action has been
accepted.

5. Device sends start-up request to secure port (18444) of provisioning service using the cli-
ent certificate received with bootstrapping message (2).
6. The provisioning service verifies the client certificate and proceeds with standard message
flow, here responds with action ReadAllItems.
