LoRaWAN Sensors (Part 2): Join and Bi-Directional Network Demonstration

LoRaWAN allows for bidirectional networks, meaning that crucial data, diagnostics and messages can be transmitted from sensors to application servers, and vice-versa. Uplink messages communicate from the sensor to the application server, while downlink messages communicate from the application to the sensor.
In order to connect to the network, devices need to go through join and activation processes. Once provisioned by a network server, join accept is indicated by an LED light. As an example, the myDevices Caynne platform offers the ability to track sensor data in a useful dashboard via a connected IoT application.

Can i get the complete joined success process in simplified way ?As i know in OTA joined process no Key sharing/communication between server and device, so fair enough as i can assume very good on security aspects. However if device and server generating key and matching then there should be some references key, is not it ? If this is the case then where is that and how can device or server will get this as nothing shared between device and server ? Is that MIC, if yes then it carries/forward to device at the end of join accepts; hence something is sharing between device and server ofcourse. I am confuse little here....
