Securing the Smart Devices in Home Automation System

Security is the major concern in every infrastructure such as offices, banks, hospitals, etc. Due to lack of security in the existing home automation system, hackers can easily access and collapse the system. Hence, in this research work, we are providing security to the remotely controlled home infrastructure and to reduce the energy consumption of smart devices. The smart device consists of the appliances such as four lights and two switches operated using the web-based application. This application allows only authorized users to remove these smart devices which are not in use for longer time and also the hacked devices. Thus, we are reducing energy consumption and securing our smart devices from hackers. Adding to the benefit of the user, through this application we can change the status of the devices either to on or off state. The status of the devices is stored in the cloud in the encrypted form (ciphertext) using the encryption technique such as the AES algorithm. Through the server using Wi-Fi module, this ciphertext can be accessed by the user credentials and decrypt it through web-based application. In this research work, major security issues like authentication and verification are taken care, and this work focus is on reduction of energy consumption by removing unnecessary devices and protecting the smart devices from hackers in the existing home automation system.
