Smart home devices are increasingly used to automate daily tasks and provide enhanced comfort and convenience. However, as these devices become universal, their security risks also increase. These risks are caused by a lack of implementation of secure safety methods embed ded within these devices and the nature of the data generated by these devices that could be used for malicious activities. In this paper, we propose an innovative approach to improve the security of smart home devices by combining Blockchain with “Vazka” Authentication. Our solution involves creating a decentralized system for managing and verifying device interactions that stores all data on the blockchain. In addition, we introduce our new authentication mechanism that uti lizes a new technique that makes two offline devices work together to decrypt a dynamic password generated instantly and get authorized access to read the data saved on the server. This provides an extra layer of security, making it more difficult for malicious actors to gain unauthorized access to smart home devices or reach collected data. We also discuss the practical considerations of using this approach, such as the need for a reliable, unique, and advanced authentication system, as well as highlight areas for future research. Overall, our proposed solution has the potential to significantly enhance the secu rity of smart home devices, providing users with more peace of mind and enabling the continued growth of this emerging market.
