IoT Based Home Automation System: Security Challenges and Solutions

Smart homes entail the integration of wireless communication and sensor technologies to enhance traditional homes by incorporating Internet of Things (IoT) enabled smart appliances. These appliances offer automation and convenience to homeowners. However, unauthorized usage of appliances remains a significant concern in smart homes. This paper explores various approaches and technological advancements in the field of smart homes. It also addresses the security challenges faced by home automation systems and proposes a practical solution to mitigate unnecessary system utilization. The solution involves the utilization of an Arduino micro-controller paired with an Ethernet shield unit, enabling monitoring of the house and its appliances. An authentication mechanism employing username and password authentication is implemented to verify the legitimacy of users, thereby preventing unauthorized access and the subsequent unauthorized usage of smart home appliances.
