A framework for enhancing the security of IoT-based Smart homes using IoT-A Reference architecture

Nowadays, smart home is considered one of the most important applications of the Internet of Things (IoT) which provides efficiency, home security, energy & cost saving to everyone’s life. Despite the advantages of this technology, privacy and security concerns require more considerations. IoT-A is considered in this paper as a reference architecture that follows evaluating protocols, making sure from the consistency of things and protocols, and providing a comprehensive solution for different applications of IoT. This paper works on IoT-A and targets this challenge in IoT and smart home, and proposes a security architecture to improve security in all levels including design, implementation, and protocols. This paper uses the term Security Framework as a way to identify all technologies, procedures, software, and other components for providing security in smart homes. At first, this paper studies all vulnerabilities and threats of the reference architecture, and then propose an improved model to satisfy all security requirements. The proposed model reasonably satisfies all security and privacy requirements of smart homes based on IoT-A.
