LoRaWAN Security
What is LoRaWAN Security?
LoRaWAN SecurityThe end-to-end key, join, and message-protection model defined by the LoRaWAN specification for low-power wide-area IoT networks.
LoRaWAN security is defined by the LoRa Alliance specifications (1.0.x and 1.1) for long-range, low-power IoT networks. Each device is provisioned with a unique DevEUI and either pre-shared session keys (ABP) or a root AppKey/NwkKey used during over-the-air activation (OTAA). After joining, two AES-128 session keys protect traffic: a Network Session Key (NwkSKey) for MIC integrity at the network server and an Application Session Key (AppSKey) for end-to-end payload encryption to the application server. LoRaWAN 1.1 strengthens the model with separate forwarding and serving network keys and a Join Server. Real-world weaknesses include weak or reused AppKeys printed on devices, ABP devices with static keys and counters vulnerable to replay, and operators that combine network and application server roles, eroding payload confidentiality.
● Examples
- 01
An asset-tracking device using OTAA with a unique AppKey to derive fresh session keys on each join.
- 02
An attacker recording an ABP uplink and replaying it because the frame counter is not enforced.
