Smart Home automatic protection system with mobile control

Abstract

Smart Home Automatic Protection System with Mobile Control. The article investigates the problem of ensuring the cybersecurity of Smart Home systems in the conditions of the rapid growth of the number of IoT devices and the intensification of network threats aimed at home intelligent environments. The aim of the work is to develop and experimentally study the architecture of the Smart Home automatic protection system with mobile control, in which cybersecurity mechanisms are integrated at all levels of the data life cycle - from sensor devices and microcontrollers to cloud infrastructure and mobile client applications. The proposed multi-level architecture is based on the use of ESP8266/ESP32 microcontrollers, the MQTT messaging protocol and a mobile control platform, supplemented by a set of protective measures, including encryption of transport traffic using TLS, user authentication and authorization mechanisms, broker access control policies, event logging systems and local algorithms for automatic response to security incidents. The paper presents the results of experimental studies of the prototype under different load modes of the Wi-Fi wireless network, within which the delays in transmitting MQTT messages, the stability of the video stream from the ESP32-CAM module, the response time of executive components and the reliability of telemetry data delivery were analyzed. The results obtained confirm the effectiveness of the proposed architecture and its ability to ensure stable operation of the automatic protection system in real time even under conditions of increased network load. The proposed approach can be used when designing practical Smart Home systems with increased requirements for cyber resilience and protection of confidential user data
