Today, building control systems are becoming a common part of modern life to provide easier management of large-scale buildings and to make all systems work more efficiently. In building control systems, various systems such as control panels, PLC, KNX, and BACnet protocols are used for process control. Building automation includes the building's heating, ventilation, air conditioning (HVAC), electricity, lighting, security camera systems, doors inside the building, elevators, and many more processes involved in control systems. However, all these systems cannot be managed from a single platform. As the demand for advanced automation systems increases, existing control systems become insufficient. In order to construct an effective automation control system, all these devices must easily communicate, integrate, and exchange information with different subsystems. The centralization of device management and the interaction of these devices with various subsystems to form an Internet of Things (IoT) ecosystem lead to the emergence of multiple security vulnerabilities. Consequently, the IoT ecosystem becomes highly susceptible to external threats, particularly cyberattacks. In this context, the integration of additional security protocols into these systems is essential to ensure the protection and reliability of the ecosystem. In this study, the design of a cloud-based smart home automation system with adding a novel security protocol has been carried out based on MQTT protocol. A prototype has been developed to test the operability of the system, and this product has been integrated into the system for operability and analysis. The system also controls and monitors the home and its surroundings through a system that works on all platforms and a mobile app.
