LoRaWAN offers two future-proof layers of end-to-end security:
- For the network that ensures mutual authentication between a LoRaWAN end-device and the LoRaWAN network as part of the network join procedure. This grants that network traffic has not been altered, only comes for a legitimate end-device authorized to join an authentic network, is not comprehensible to eavesdroppers, and has not been captured and replayed by rogue actors.
- For the application that ensures the network operator does not have access to the end user’s application data. LoRaWAN is one of the few IoT network implementing end-to-end encryption for application payloads exchanged between the end-devices and applications servers. In traditional cellular networks, the traffic is encrypted over the air interface but transmitted as plain text in the operator’s core network, requesting the user to select and deploy an additional security layer (VPN or dedicated security layer encryption application).
