Designing a Secure IOT data Encryption algorithm for Smart Environmental Monitoring System

Abstract

There are many applications where it is required to smartly monitor the environmental parameters. Therefore in this paper a smart IOT based environmental data monitoring system Transceiver is designed. The Humidity of the air is responsible for the various chemical and biological properties of the environment. Therefore humidity and temperature data sensors are used for environmental air monitoring. A secure key based AES encryption standards is used at the transmitting end. The cipher data is uploaded over IOT cloud. At the receiver end a smart decryption algorithm is designed. The NodeMCU based ESP8266 Wi-Fi router is designed at the transceiver end. Paper present the secure environmental monitoring system, which is applicable in air conditioning, ventilation and weather monitoring. The data is stored over ThingSpeak cloud server.
