IOT BASED SECURE AND SMART FARMING SYSTEM

Abstract

Internet of Things (IoT) smart and secure farming solutions are made to monitor agriculture fields by automating irrigation systems and utilizing sensors. It refers to managing farms using contemporary information and communication technologies to grow to maximize the amount of human work needed while increasing the number and quality of products produced. An IoT-based smart and secure farming system helps farmers save costs in several ways. Field programmable gate array (FPGA) boards and ESP8266 were used on the transmitter interfaced with the DHT11, soil moisture sensor, PIR motion sensor, and buzzer and communicate wirelessly using the sender and receiver sides equipped with ESP8266 to send the data without the internet. After collecting sensor data from the DHT11 and soil moisture sensor, the FPGA uses the secret key to encrypt the data before sending it from the transmitter side using the multiple ring oscillator-based TRNG architecture, which consumes only 2 LUTs and 2 DFFs and an exclusive-OR (XOR) function. After being decrypted at the receiver, the sensors' values were appropriately displayed and transferred to the ThingSpeak cloud for real-time monitoring. The proposed TRNG-based IoT system is low-power and highly secure, making it ideal for standalone applications.
