Today, the smart home is one of the main and growing applications of the Internet of Things, which brings comfort, security, reduced energy consumption and cost of living. In addition to the benefits and advantages that this technology has brought, the issue of security and privacy has become one of the major concerns that needs serious attention. The IoT-A reference architecture is based on examining existing protocols and resources, ensuring the compatibility of objects and communication protocols, and providing a comprehensive solution for various IoT applications. This paper seeks to provide a general framework for improving security at all levels of design, implementation, and use of equipment and protocols, using the IoT-A reference architecture to address the security challenge of the Internet of Things and smart homes. In this article, the term security framework is used to identify the set of technologies, mechanisms, software and components needed to provide a set of security needs. After examining and mapping vulnerabilities and threats in the architectural application model, this paper presents an improved security framework compared to the standard reference architecture framework. Based on the theoretical evaluation, the new framework, which was formed by adding two components of threat and vulnerability management and field management and making some changes in the licensing component, meets the security requirements of the smart home to an acceptable level and provides an appropriate degree of security and protection. Enhances IoT-A-based smart home privacy.
