An App key needs to be preconfigured in the Network Server and is used to
validate that the device has permission to communicate with the network.
These values are user configurable and devices can be supplied pre-
configured with alternative values as part of Service Bureau customisation
service.
Once Network Server accepts join request, the device then generates
following session keys based on App Key,
•
NwSKey (Network Session Key): To be shared with Network server
•
AppSKey (Application Session Key): To be shared with Application
Server, this ensures end to end encryption of pay load data.
Beacons are then received by LoRa gateway and forwarded to
Network Server which will push data to the end application server.
