2.2.1.1 AES Key Storage

ATECC608B-LoRaWAN

2.2.1.1 AES Key Storage

LoRa Security is built around 128-bit AES symmetric keys. A wide variety of AES keys have been implemented to support the LoRaWAN specification in the ATECC608B-TNGLoRaWAN device. These include:

Network and Application parent keys
Application sessions keys
Various types of Network and Server encryption keys
Network and Server integrity keys

The KDF command in AES mode should be used to generate the necessary LoRaWAN session keys based on the AES parent keys stored in Slot 0. Optionally, these keys can be written as clear text. These keys are still considered secret and therefore can only be read via an encrypted read.
