Abstract

LoRaWAN is one of the emerging Low Power Wide Area Networks being developed for IoT applications which can be applied to Industrial Control System (ICS). The latest LoRaWAN release v.1.1 uses Advanced Encryption Standard Electronic (AES) with 128 bits key for encryption and authentication. The release has a security framework which covers the end devices, LoRaWAN gateways, network servers and application servers. In its key management part, the key generation is recommended, but not clearly specified. However, the key generation is a very important part of the security key management scheme, as it will affect the soundness of the whole security framework. In this paper, a new key generation scheme for LoRaWAN is proposed. The scheme has been shown that it not only has high computing efficiency but also meets the randomness requirement of the security key. The proposed scheme can enhance the LoRaWAN security framework if it is adopted in its future release.
