With LoRaWAN OTAA end devices are provisioned with root keys. In OTAA activation, an end device performs a join procedure with a LoRaWAN network, during which a dynamic DevAddr is assigned to an end device, and root keys are utilized to derive session keys. Hence, DevAddr and session keys change as each new session is established.[1]
