Bài viết này trình bày đến nghiên cứu ứng dụng thuật toán mã hóa đối xứng AES 128 bit trong mạng cảm biến diện rộng LoRa để bảo mật truyền dữ liệu giữa các thiết bị IoT và web server thông qua thiết bị LoRa Gateway. | Journal of Mining and Earth Sciences Vol. 63 Issue 1 2022 105 - 114 105 Applying AES algorithm for secure data transmission between Sensor node and LoRa Gateway to Web Server Chi Van Dang 1 Khoat Duc Nguyen 1 Luc The Nguyen1 Dung Ngoc Le 2 Quan Hong Luu 2 Son Thanh Huynh 2 1 Faculty of Electromechanics Hanoi University of Mining and Geology Vietnam 2 Dong Nai Technology University Vietnam ARTICLE INFO ABSTRACT Article history Lora Gateway is an intermediary device that can connect devices in the IoT Received 1st Sep. 2021 system. IoT is the Internet of Things consisting of a system of interrelated Accepted 20th Dec. 2021 digital and mechanical devices and machines capable of transmitting data Available online 28th Feb. 2022 over a network without requiring human-computer interaction. Lora is a Keywords long distance wireless communication technology that enables AES algorithm communication over a wide range between devices. Through this device the Sensor nodes in the IoT system can transmit and receive data by LoRa Data transmission waves to the Gateway and by Wifi 3G to the web server via the Internet. Internet of Thing IoT Data communicates in the internet environment so important information Security LoRa Gateway needs to be protected by data encryption. This paper presents research and Web server. application of 128-bit AES symmetric encryption algorithm in LoRa wide area sensor network to secure data transmission between IoT devices and web server through LoRa Gateway device. The research team has designed and built models for testing sensor stations with integrated humidity and temperature sensors LoRa Gateway integrating Lora module and wifi 3G module developing the interface on web server with decoding monitoring and data storage features and proposing a solution with AES encryption algorithm and architecture applied in the development of embedded software for LoRa module. The research results are tested on the model to test the encryption data .
