Evaluation of Encryption and Decryption Data Packet Delivery Performance in Smart Home Design using the LoRaWAN Protocol

LoRaWAN was built to allow long distance communication with a low bit rate and an encrypted system using the 128bit key of Advanced Encryption Standard (AES) algorithm for the messages encryption and decryption. With the various advantages offered by LoRaWAN. However, some features of LoRa technology also bring new security weaknesses. Therefore, we propose an integration encryption method between a mobile application for IoT monitoring system and the LoRaWAN server. With this method it is able to answer security challenges in the application of IoT, but due to limited use and devices, an analysis of the performance of the LoRaWanprotocol is needed for the data encryption process carried out on an integrated smart home system based on the Android-based application. Therefore, this research is focused on analyzing the performance of the LoRaWAnprotocol for data transmission in smart home systems by considering the security of the data information sent. So as to create an IoT-based smart home system that is more efficient and remains safe when used. From the results of this study, it was found that the LoRaWAN protocol still has a vulnerability in the security of its data payload packet because it is not encrypted and this vulnerability is proven in data monitoring tests.
