Abstract: Cyber physical systems (CPS) is a ubiquitous concept where objects are connected to the internet and equipped with an ability to sense physical medium and transmit data through network. In recent years, smart home applications have gained popularity due to their various benefits like time-saving, low cost, optimised electricity use. The main component of the CPS is a low-capacity sensor node. Due to resource limitations like low storage space and limited processing power, the well-known security mechanisms used in desktop devices fail to run on these systems. For secure smart home systems, this research paper proposes a lightweight key agreement and authentication mechanism. It protects against various cyberattacks. It also provides communication security, privacy protection for end-users, and a low-cost system for sustainable production. The system's proof-of-concept prototype has been implemented, demonstrating the system's feasibility. The real-world experiments show the system's effectiveness and efficiency in various scenarios.
