Security has always been an important aspect for any wireless technology. LoRaWAN utilizes two layers of security: one for the network and one for the application. The network security ensures authenticity of the node in the network, while the application layer of security ensures the network operator doesn’t have access to the end user’s application data. AES encryption is used with the key exchange.
An added bonus is that low-power Chirp Spread Spectrum signals are very difficult to detect and intercept.
