Security

LoRaWAN devices encrypt their binary messages using AES128 CTR mode before they are transmitted over the air. Transport Layer Security (TLS) encryption is used further upstream between the LoRaWAN gateway and AWS IoT Core.

Refer to Data Security with AWS IoT Core for LoRaWAN for details on how data security is addressed between each component.
